Looking at it again, were you saying the old pod was 57&3/4" long & not 57" long with a wall thickness of 3/4" as I interpreted it. If so then what is the wall thickness of the old pod thanks.

Originally you said your new pods were 6ft long ( 72") In the latest email I am reading that you are now saying they are 57 & 1/4" long! Or is this the old pod length. Once I get the dimensions right I'll calculate your old pod thickness at 1/4". We will get there eventually.

They both have the same power and have four channels available.? You'll notice that to get the SSB-2010 configured for land use (conversion kit) it will cost you about the same money as the STX-101 although it represents a savings of $200 or so. The only "advantage" of the STX-101 that I can possibly see is that if you want more than one person to listen in on the conversation, it has a built in speaker.? However, after experience with two different STX-101 units I will say the audio clarity between the STX-101 speaker and the SSB-2010 headset is dramatic, in favor of the SSB-2010.? I have found the audio from the STX-101 often to be difficult to understand and very sensitive to minor volume/squelch changes.? By contrast, the SSB-2010 in Cliff's R-300 had very clear audio.? I am hoping the difference is because the speaker in the STX-101 has some plastic over it to protect it from water splashes which is interfering with good transfer of speaker vibration.? I will be very interested to try the headset with the STX-101 surface unit to see if the audio is better. The SSB-2010 does have some advantages on it's own in my opinion.? It is waterproof to 500 feet so if water does get on it or it goes overboard by accident there's no loss from water infiltration.? It's pretty aggravating being in a small dinghy trying to keep water from splashing on the much larger STX-101 and also concentrating on communications.? I am probably going to mount my STX-101 in the submarine for that reason.? However if I had it to over again I would just go with two SSB-2010.? In fact, I'll sell you my STX-101 if you want it.? :) Jon From: Alan via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Wednesday, August 1, 2018 7:17 PM Subject: Re: [PSUBS-MAILIST] Comms for the SeaQuestor Sub Thanks David,I have to go through this process so anything you can tell meis helpful.I presume you will be buying this conversion kit for the SSB210.http://oceantechnologysystems.mwrc.net/en/product.php?product_id=44774I believe Scott has this setup.OTS says you can convert the SSB210 in to a surface unit with the?conversion kit, & I am wondering what advantage the standard surfaceunit has over the converted SSB10.

One of my friends who helps out with the sub is an electrical engineer and some time ago took on, as a special project, figuring out how we might use a generic head set and mic with the SSB-2010. It was just to save money and make replacement readily available given how much OTS charges. He managed it, and it consists of a little bit of circuitry in a small enclosure with plugs for the headset and mic, and a push-to-talk button. The connector from the enclosure to the OTS unit we had to get from OTS, but luckily they sell that as a spare part.

Or $189- for the shorter cable at http://oceantechnologysystems.mwrc.net/en/product.php?product_id=44912 The conversion kit I mentioned is $729- & only has the headset & transducer. So if that $189- transducer plugs in to the SB 2010 you could do the conversion for under $250 using Alec's piece of electronics on an alternative headset. Double the savings in my case if I go for a converted SB 2010 for a surface unit. Alec, If that electronics is just the push to talk function would it be something like a single pole double throw momentary switch. That would mean you push the button & there is a connection to the mike & a break in connection to the headset. Or is it more complicated than that? Don't want to get you to pull your unit apart. Jon, thanks for that info. I am now leaning heavily toward 2 x SB 2010. If anyone knows what depth the transducers are rated for I would be interested.

We already know we can get the connectors that attach to the SSB-2010 unit. The interesting part would be how the audio quality from a $50 "walmart" unit matches against the $500 OTS unit.?

Not taking the batteries into consideration as they stay the same. Old pod is 61.85 lb buoyant. New pod is 151.62 lb buoyant. You need 89.77 lb x 2 = 179.54 lb to get back to your original neutral buoyancy. So you weren't far off with the 150 lb you added. Hank said 166 lb so we are only 13.5lb different in our calculations. If you can't put the lead under the sub, & you have a small section of the new pod pipe, you could clamp a wall at either end & cast lead in to it so that you have lead in manageable sections contoured to your battery pod that can fit under your batteries. You could use wooden spacers between sections of lead to adjust your subs trim.

Or $189- for the shorter cable at http://oceantechnologysystems.mwrc.net/en/product.php?product_id=44912 The conversion kit I mentioned is $729- & only has the headset & transducer. So if that $189- transducer plugs in to the SB 2010 you could do the conversion for under $250 using Alec's piece of electronics on an alternative headset. Double the savings in my case if I go for a converted SB 2010 for a surface unit. Alec, If that electronics is just the push to talk function would it be something like a single pole double throw momentary switch. That would mean you push the button & there is a connection to the mike & a break in connection to the headset. Or is it more complicated than that? Don't want to get you to pull your unit apart. Jon, thanks for that info. I am now leaning heavily toward 2 x SB 2010. If anyone knows what depth the transducers are rated for I would be interested.

The headset looks reasonably cheap but easy to upgrade. What I can't find anywhere is a Watt rating for any of the Ocean Reef units. When I'm comparing Ocean Reef with OTS, all other things being equal, the Watts is what will give me the longer range.

In reverse there is no thrust bearing to take the axial load, just a circlip against a washer, against the face of a bush. So you would get less thrust in reverse because of this. I am not sure whether the prop is as efficient in reverse as it is forward. It makes sense to orient it so that reverse is used least. However unless you are going to be positively buoyant you would be using it the same amount in both directions. Orientation might be dictated by where you can mount it, as it would be a foot higher or lower depending on the rotation. Do you want to keep it slightly further away from the bottom to avoid stirring sediment or entanglement, or further under the water so you can thrust down sooner when descending. Am also interested in what peoples preferences are here. Thanks for the Nuytco post. Wonder how big that tank is. It must be small enough to be transported.

I'd hate to run the thrusters in reverse the whole time during a dive. I orient them so they push the sub down, and dive slightly buoyant. That has two advantages. The prop wash is directed away from the bottom, so you don't ruin visibility. And if something malfunctions, the sub surfaces as a fail-safe.

Without them, if one of my horizontal thrusters, or more likely motor controllers failed, I would go around in circles. I imagine it would be easier to drop a rotating thruster than a fixed thruster. Having said that I am now having 2 fixed & 4 horizontal thrusters, reason being it will give me more room inside my one person sub not having the rotating mechanism & because I am making my thrusters, adding extra isn't too expensive. One of my thoughts on the rotating thruster was to have it operated by a motor. There are some incredibly powerful & inexpensive geared motors about that could handle that.

At least for a conventional Kittredge-type sub. Shackleton has two 100lb Minnesota?s for vertical thrust. That?s nominal and I recall actual thrust being a considerably less. They?re angled to enable crabbing, which takes away some from vertical efficiency. Their prop wash goes through a grated deck, losing some more. The net vertical force is probably well under 100 pounds between them - compared to 900 lbs from the MBTs and close to 200 from the drop weight. I?ve come to think of thrusters as tools for maneuvering, but not really for solving an emergency with brute force.

At least for a conventional Kittredge-type sub. Shackleton has two 100lb Minnesota?s for vertical thrust. That?s nominal and I recall actual thrust being a considerably less. They?re angled to enable crabbing, which takes away some from vertical efficiency. Their prop wash goes through a grated deck, losing some more. The net vertical force is probably well under 100 pounds between them - compared to 900 lbs from the MBTs and close to 200 from the drop weight. I?ve come to think of thrusters as tools for maneuvering, but not really for solving an emergency with brute force.

I won't be doing this and the reason is that when I first designed my boat, I had lots of buttons on my joystick. I could execute MBT blow and flood, VBT blow and flood, correct trim in boat as well as several other functions. What I found from using it was it was hard to use the buttons. I would have to take my eyes off where I was going and look down to the joystick to use the buttons which were kind of small. The joystick was also located between my legs lake like in an old style airplane. This made it hard to get in and out of the seat. I ended up ripping out this joystick and replacing it with a 3-Axis joystick that has no buttons that is mounted along the hull on the starboard side. My boat is small and this helps getting in and out of the boat. Buttons are now on panel on the starboard side of the boat. This has worked better for me. I think the joystick orientation and function are more important to 'flyers" as apposed to 'K-boats" because of the sensitivity of joystick movement given the widely different GC-GB spreads between the two design philosophies. For example in my boat, slight movements to the starboard or port sides with the joystick, can cause the boat to roll +/- 30 degrees. This is Ok if you want to roll but if you are just trying to punch a button on the joystick, it's kind of unsettling.

I'd hate to run the thrusters in reverse the whole time during a dive. I orient them so they push the sub down, and dive slightly buoyant. That has two advantages. The prop wash is directed away from the bottom, so you don't ruin visibility. And if something malfunctions, the sub surfaces as a fail-safe. >>> >>> Best, >>> Alec >>> >>>> On Thu, Aug 9, 2018 at 8:35 PM Jon Wallace via Personal_Submersibles wrote: >>>> >>>> For those of you using fixed thrusters for vertical diving and ascent, I am curious if you orient the normally "forward" thrust to propel your vessel upwards or downwards. My assumption is that there is less thrust produced in the "reverse" direction of a minn-kota than the "forward" direction. I have been thinking that I probably want to orient my motors to produce maximum thrust for surfacing rather than diving, but not sure it matters.

I might leave my planned screen scrolling buttons off the joystick. Was going to be hard work putting them in. Glad to hear you are getting enough roll to make that function worth while. I had been talked in to incorporating roll & have a rotating 3rd axis on my joystick that can be used for that. I have a small sliding top hat sized joy stick that I am adding to my main joystick for the vertical thrusters, but aren't sure that I will have enough range of movement on it to get enough sensitivity to hover. In case you guys aren't familiar with the radio control World; you can program in an exponential movement from the joy stick. Ie. For an 80% movement of the joystick you could have the motor only going at 40% of it's speed ( instead of 80%) giving twice the sensitivity for the range where you need to hover off the bottom.

It allowed me to look out the port side and see the bottom while moving forward. I wonder the difference with your acrobat mode in open water.

I won't be doing this and the reason is that when I first designed my boat, I had lots of buttons on my joystick. I could execute MBT blow and flood, VBT blow and flood, correct trim in boat as well as several other functions. What I found from using it was it was hard to use the buttons. I would have to take my eyes off where I was going and look down to the joystick to use the buttons which were kind of small. The joystick was also located between my legs lake like in an old style airplane. This made it hard to get in and out of the seat. I ended up ripping out this joystick and replacing it with a 3-Axis joystick that has no buttons that is mounted along the hull on the starboard side. My boat is small and this helps getting in and out of the boat. Buttons are now on panel on the starboard side of the boat. This has worked better for me. I think the joystick orientation and function are more important to 'flyers" as apposed to 'K-boats" because of the sensitivity of joystick movement given the widely different GC-GB spreads between the two design philosophies. For example in my boat, slight movements to the starboard or port sides with the joystick, can cause the boat to roll +/- 30 degrees. This is Ok if you want to roll but if you are just trying to punch a button on the joystick, it's kind of unsettling. >> >> Cliff >> >>> On Sun, Aug 5, 2018 at 3:06 PM, Alan via Personal_Submersibles wrote: >>> David, Cliff, >>> just had the thought that if you are using a flight controller style >>> joystick you could wire up your push to talk button on your coms >>> to that.

(.38 ft lbs) So you would probably have to gear it anyway, or buy a motor controller that could handle a lot of amps. They sell motor controllers for that motor. The only thing that can be a bit problematic with the brushless motor controllers is that if they are designed for the hobby market they are normally operated via a transmitter & receiver not a potentiometer. There are electronics to get round that. I just bought a pressure sensor / temperature sensor & underwater switch off Blue Robotics. I am sure that actuator motor will be DC. I will be interested to hear how you get on with it.

The linear actuator is just a turning threaded rod; if we used an exposed underwater motor like the blue robotics item & corrosion resistant gear box to drive a threaded stainless shaft, you wouldn't need to oil compensate & seal the actuator & could have as much travel as you wanted. You could even have enough travel to push the 400lb weight off the end of it's track, making it a drop weight.

Would it not be better to try & get under the water & check that you don't topple over? If you are unstable you can always add flotation up high & lead down low. If you do that shell you may be forced to destroy it in the process of rectifying stability issues.

The initial fabrication is almost complete and I was thinking that I might want to have the parts sand blasted prior to welding them all together. Maybe even a light primer seal coat to slow flash rust as it may be at the welders for a couple of weeks. Any thoughts or advice would be appreciated.

They should be prepping the joints just prior to welding so that's shouldn't be an issue, plus the heat is going to discolor and/or burn any surrounding paint.? When you get it back, sandblast and prime the whole thing. However...given the difficulty of both prepping and painting the interior, I think I would take the opportunity to get as much of that done first, as possible.? You can touch up afterwards any burn marks from welding but at least the bulk of it would be finished.

This seal will see the salt water & crut that is forced passed it by the propeller, & wear first.

I would consult your sand blaster to see if he is going to have problems getting in to the nose cone area. And also whoever is going to paint it to check that the intended primer doesn't have a set time by which it needs to have the next coat applied & that it is compatible with your intended marine paint system. If they specialise in marine paint application they should be able to give you advise on when to prime. I painted my sub with marine epoxy but had to buy specialised equipment to apply the extra thick paint. Started to get expensive. You may have a lot of attachment brackets you want to weld in for seats coms, scrubber, piping etc that you position at a later stage & that might burn your external primer. Another thought is that if you are getting it blasted professionally you don't want to do it twice. You want them to do it once just before painting & clean up around the welds for you.

There is some advice below, but again I would sought your paint system first & see if the method is compatible. https://www.americandrystripping.com/protect-metal-abrasive-blasting/ recommends..... For short-term surface protection ? and to help paint adhesion ? newly media blasted parts should be washed with metal prep ? a dilute phosphoric acid solution available from auto parts stores as a painting preparation product under a variety of names.

And to honest, we chased the loads and added additional steel and reinforcing, and then the load stress moved somewhere else, and we would chase it again. Ultimately the initial design parameters were exceeded in the weight of the sub, and we never could hit the 1000ft mark. So after a conversation with Cliff, who brought me back to my senses, I put my ego in my back pocket, and settled on the 500ft mark, as we were able to achieve all of my initial design parameters on the first run of the FEA. I know that my design is not the standard k boat, but having been in a few I found that I wanted a bigger sail diameter to accommodate all of my instruments, and my shoulders. This decision I believe was the main reason we could not hit the 1000ft mark. But I'm ok with the depth. Our main pilot sail is 32"od, with a 30"od acrylic dome. The forward sail is 27.5"od. with same dome size. Plenty of room for looking around. I think were forming the forward sail today. So I may have an updated photo soon.

So what I'm saying, is that the tongue could go up another couple of inches but I can't raise the ball because the coupler is already cocked on it instead of level.?

Here's an example: https://www.ebay.com.au/itm/50A-wireless-DC-volt-AMP-power-meter-Battery-Monitor-capacity-Coulomb-counter/302719224914?hash=item467b78cc52:g:UvwAAOSw8Pda4xI7 They typically come with a sensor module you install in the power line, and then a display (usually with a lot of information) to install within bluetooth range and power separately. It's a great way to avoid running signal wires and get diagnostics. Getting the bluetooth sensor to talk to something other than the display that comes with it may or may not require some hacking and code.

Can't help you with the seals as my motors are external. I have been making my own thrusters & have contacted seal reps & even emailed the manufacturer for advice on a non standard mounting method I was proposing. Normally seals are used on pumps to keep fluid that is under pressure in rather than out as in our case. I did a quick calculation on your pressure vessel & it came out as a 600ft crush depth. Don't take that as gospel, but it may be worth looking at it in depth if you haven't already. If the 600ft is right you could dive to 300ft with that hull! For all the work that goes in to building a submarine you may find that it is only a relatively small amount of extra effort & cost to give you an extra 200 ft of diving capability. I would think about this first before choosing a seal as the added pressure may have bearing on your choice.

I was told the thrust bearings require more precise tolerances & the deep grove ball bearings would be fine. You mentioned you were using a 10hp motor; the link below is a 11.5hp motor & it is developing 254lb thrust https://www.max-power.com/product/18-electric-tunnel-thrusters/5115-electric-tunnel-thruster-ct-125 So choose a deep grove ball bearing that is rated for a 250lb axial load. If they don't state the axial load when you look at the bearing description it is generally a certain percentage of it's maximum radial load (forgotten).

It's not clear to me what kind of seal to use (many other parts Captain K. was spacific about, like o-rings and valves) or the size.Thank you for your recomendation for All Seals Inc.? I bookmarked their website some weeks ago and intend on paying them a visit next week (I've got to wait until I get paid on Saturday).? Fortunately, I live only a few miles from their Lake Forest location. I think I've seen a seal that will work for me in their catalog and a calculation that shows how much room I need (after compressing the spring) to firmly hold the seal in place inside the through hull connection.? Now I need some education in bearings.? There is another site that I may contact about those if no one on this list has a recommendation for me.?

However those results indicated that if you did some serious calculations you could go a lot deeper than you intended. There are some talented people in the group with regard to hull calculations & reinforcement etc. ( I'm not one of them) I am sure if you asked for an opinion on your pressure vessels crush depth you would get some good advice. Have you had a look at the "Guernsey Submarine" site? http://www.guernseysubmarine.com A great resource there, with supplier links. Anything you aren't sure of just ask.

The other suggestion is that where possible lengthen the wires from the speed controller to the motor rather than battery to speed controller. Below is a quote from a guy that has been designing motors & controllers for 30 years. Alan I will repeat the message previously given. I hope you heed some sound advice based on theory and practice. 1. wire resistance my rob you of a bit of power but will not destroy your speed control or motor. 2. wire inductance will not damage your motor nor will you be able to detect any effect even with 100 feet of wire. 3. wire inductance will kill the mosfets in your control and may even blow the caps I am a design engineer and manufacturer of motors and controls for over 30 years. you must keep battery wires as short as practical . short means 1 foot or less. brushed or brushless makes no difference. here are some example of problems some customer have had 1. blimp 30 feet of wire to speed control and steering motor in the tail. control voltage rating 60 volts 50amps motor load 12v 20 amps result instant smoke first run of motor. I replaced control at no cost . same result instant smoke. then i was told about long wires ran a test with 3 ft cord result 30 volt swithching spikes on 100 uf input cap. had customer put control near battery in gondola. 30 ft wire to motor end of problems. we have customers running very long wires to motors for industrial applications with no problems. hundreds of feet or more. on robots running two or more motors on one battery. 2 feet battery wires to non opto coupled controls will make motors hunt. no problem with opto coupled controls. with BEC controls keep battery wires short.

The unstiffened cylinder calculator and Cliff's hull spreadsheet are pretty close, the former at 315 feet and latter at 308 feet.? Both are based upon ABS rules but Cliff's spreadsheet does consider some of the finer and nuanced points of failure.? There is one section of Cliff's spreadsheet calculator (inertia requirement) that shows a cause of concern but I think it is due to the fact that his spreadsheet requires stiffeners for this section to be calculated correctly and I assume Jim's cylinder has none.? The spreadsheet will not accept "0" for a stiffener dimension to simulate a cylinder with no stiffeners, so I usually enter ".01" as a value with the distance between stiffeners the overall length of the hull to represent an insignificant stiffener effect.? Using .01 for stiffener values, the "inertia requirement" section shows max depth of 5 feet.? Using K-boat stiffener values the same section shows max depth of 101 feet, and using more appropriate stiffener values for this hull of .625 thickness and 2 inch flange the same section shows max depth of 227 feet.? Now, I'm pretty sure...would bet money on it...that Jim's hull will easily survive 5 foot of depth without collapsing so I don't know how to really interpret the inertia requirement section of the spreadsheet in this case. Sean's calculator doesn't seem to take into account cylinder length so I couldn't use it as a triple check on the other two calculators. At this point Jim, I would tread cautiously with max depth until you (or we) are comfortable with a figure.? Personally, I think your original max depth of 100 feet is reasonably appropriate.? An unmanned test dive when the sub is ready would be highly encouraged.

There wasn't enough material for a proper documentary, and arguably there isn't even a plot. But the goal of this short piece is to demonstrate how enthusiastic scientists get when offered an opportunity to dive in subs, and that we can offer such opportunities safely and professionally. For those of us lucky enough to have a sub, it's a lot more rewarding to use it for real purpose. For the scientists, it's an opportunity to finally see the subjects of their study face to face, and to go deeper than on SCUBA. I will be sending out a FB update too, so if you are on that I'd really appreciate sharing. If you are on any other sort of social network, I'd really appreciate sharing links to the website and/or video. The idea is to get the word out to the educational and research communities, as surely there are neat ideas for future expeditions within those groups. The video is accessible from either the Expeditions or Videos tab: https://www.innerspacescience.org/ Many thanks to everyone who pitched in on this initial expedition. Particularly to Cliff and Hank, who towed their boats half way across a continent. To Jon and Dan, who coordinated surface operations. To Ian, Brian, and David who were support divers. And to Shanee, who not only contributed an inflatable but jumped into the freezing water without a wetsuit to retrieve the glasses I so cleverly dropped off the dock.

I'd like to see Cliff and Sean respond. The unstiffened cylinder calculator and Cliff's hull spreadsheet are pretty close, the former at 315 feet and latter at 308 feet. Both are based upon ABS rules but Cliff's spreadsheet does consider some of the finer and nuanced points of failure. There is one section of Cliff's spreadsheet calculator (inertia requirement) that shows a cause of concern but I think it is due to the fact that his spreadsheet requires stiffeners for this section to be calculated correctly and I assume Jim's cylinder has none. The spreadsheet will not accept "0" for a stiffener dimension to simulate a cylinder with no stiffeners, so I usually enter ".01" as a value with the distance between stiffeners the overall length of the hull to represent an insignificant stiffener effect. Using .01 for stiffener values, the "inertia requirement" section shows max depth of 5 feet. Using K-boat stiffener values the same section shows max depth of 101 feet, and using more appropriate stiffener values for this hull of .625 thickness and 2 inch flange the same section shows max depth of 227 feet. Now, I'm pretty sure...would bet money on it...that Jim's hull will easily survive 5 foot of depth without collapsing so I don't know how to really interpret the inertia requirement section of the spreadsheet in this case. Sean's calculator doesn't seem to take into account cylinder length so I couldn't use it as a triple check on the other two calculators. At this point Jim, I would tread cautiously with max depth until you (or we) are comfortable with a figure. Personally, I think your original max depth of 100 feet is reasonably appropriate. An unmanned test dive when the sub is ready would be highly encouraged.

Thanks Allen for that hull calculation! I hope you're right! I thought it might be shallower than that without reinforcement.

Still, this being my first boat I don't really want to go deeper than I could safely get up from on SCUBA (I've got a 2" flood valve if I ever need to get out while on the bottom).

Don't take that as gospel, but it may be worth looking at it in depth if you haven't already. If the 600ft is right you could dive to 300ft with that hull! For all the work that goes in to building a submarine you may find that it is only a relatively small amount of extra effort & cost to give you an extra 200 ft of diving capability.

Not sure if the 12.5' length is overall or SS (seam to seam). Also we need details of stiffeners including dimensions of the inner stiffeners and spacing. The ABS spreadsheet is for stiffened cylinders. As you note, you can trick the spreadsheet by putting some stiffeners in with 0.001 web and flange thickness. If you do this, then you need to ignore results (maximum allowable working pressures) associated with stiffeners and just look at the depth associated with overall buckling. With this diameter of a hull, even with 0.625" wall it really should have stiffeners to address the concern of overall buckling.

With that in mind, I used 150 inch length seam to seam since I didn't have info about the tank heads.? Those would have to be calculated separately anyway to determine which was weaker, the cylinder or the heads.? I also assumed no stiffeners, just a hollow cylinder with two tank heads. Using 150 for Line #12 (Ls) and Line #15 (Lc) in addition to .001 for stiffeners, the spreadsheet shows overall buckling (Line 63) is 842 psi with n=.5 which seems unreasonably high.? I think the inter-stiffener Pa result is still valid since ABS uses the same inter-stiffener strength calculations for unstiffened cylinders with the exception that F is not calculated but assigned a static value of "0".? However, I do defer to your expertise.

I would think about this first beforechoosing a seal as the added pressure may have bearing on your choice.All the best,Alan (New Zealand) _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles -------------- next part -------------- An HTML attachment was scrubbed...

Fortunately, I live only a few miles from their Lake Forest location. I think I've seen a seal that will work for me in their catalog and a calculation that shows how much room I need (after compressing the spring) to firmly hold the seal in place inside the through hull connection.? Now I need some education in bearings.? There is another site that I may contact about those if no one on this list has a recommendation for me.?

That's interesting that you are having 2 separate pressure vessels, I had always thought it was one! Never mind about Minn kotta, I am making some progress with my brushless thrusters. Received 11 motors that were made to my specs, with stainless propeller shafts. Have 3 different Vescs ( Benjamin Vedder designed speed controller) that I am testing & an amazing program called the Vesc Tool for setting the speed controller & it's input devices parameters. You can attach your Vesc & motor to a laptop via usb & dial a load & rpm in to it. The Vesc Tool displays temperature of the esc & motor as well as Amp draw, Voltage & motor rpm. So with this I can establish a maximum amp draw for the esc & motor then choose a propeller that will give me that load. Maybe I will do a video later!

The main reason is the base line thrust increased by 11% because of more power. My boat is already set up to handle 60 amps per motor so this increase current is not an issue. I can use the same ducted nozzle I am using now but will have to redesign the supports. Because the body is a large diameter (4.5" OD vs 4" OD), this means that the aftermarket prop makers like Kipawa have already come out with a 3 bladed prop (Kipawa 112). Because the motor diameter is larger, their 3- bladed prop diameter is larger. This means I can take this cheap $35 prop and turn it down to fit in my existing nozzle. This solves one of my problems which is having an inexpensive blade that is wide at the tip to minimize pressure leakage from the high pressure side to the low pressure side cause by putting an open water prop in a ducted nozzle. This should boost the performance of this cheap prop both from being a better match with the nozzle and the 11% baseline improvement in power of the motor. As to seals, I am not sure what changes they have made (MK 101 have two lip seals) but since we pressure compensate these motors, the load on the seals in low anyway. All in all, I think this good new for psubbers that use the MK lower units as thrusters. I can see another R-300 project in the works which would be to upgrade to these lower units and repeat the bollard thrust test to see how they perform.
