<html><head></head><body><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;"><div>Hi Jon,</div><div>Thank you for your advice! I've not looked at the motor pod drawings of the K250 in more than a decade because when I first started out I bought two 40# thrust motors from the Kent Corporation and figured I would just use those. Looking at the drawings now I can't seem to see the details I think I would need build (or tell my nephew how to build) such a part. 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.</div><div>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. Thanks again!</div><div>God bless, Jim</div><div id="yahoo_quoted_5642602902" class="yahoo_quoted">

If I'm understanding your need correctly, won't the K-250 motor pod drawings work for you since they employ a mechanical seal.

years now. Long before now I’ve intended
on making my presents known to the whole group (I’ve contacted several members
off list over the years) but have always seemed too busy to do so… Well, now
I’ve pretty much got all the time in the world and am using much of it to
finish building my sub…</div>

15 years now…</div>

blueprints) but morphed into something of a money pit since the day I saw and
bought a “real bargain” (a giant pressure vessel) at a wrecking yard. The pressure vessel that I’m using for my
hull is 12.5’ long, 5’ in diameter and 5/8” thick. It would have cost about $15K new, but I got
it for $300! My boat will be named
“Pipedream” when it’s done because my original idea called for the hull section
being made from a piece of pipe. I don’t
plan on going deeper than 100 feet and will likely stay above 60 feet most of
the time.</div>
<div id="yiv2107503489yui_3_16_0_ym19_1_1535383452172_6032">One of the reasons I’ve finally surfaced on this list is to
ask for help. Does anyone have a working
plan / blueprint of a through hull connection for a drive shaft? Or can someone direct me to one? I’ve got a 10 horsepower motor for propulsion
that I plan on using to turn a 1 inch diameter, 5 foot long shaft with a 12”
propeller. I’ve read all I can find
about mechanical seals and watched all the youtube videos on them that I could
find…. Can anyone recommend specific mechanical seals and bearings
(manufacturer / source or catalog number)?
My nephew in Texas works at a machine shop and assured me that with the
equipment he has, that he can make anything I ask for if I can only get him a basic
blueprint or plans for a part with the seals and bearings that I need inside. I need to wrap up the issue with the through
hull ASAP as the guy who has done most of my welding is moving next month and I
don’t want to get someone new to put that part in (the welder I have is VERY
good at what he does). I would be very
grateful if someone could help me with this particular issue.
