At present I have the wires running through a clear hose up to a manifold.</div><div>I say manifold but it is a modified brass T plumbing fitting. The hose is hose clamped</div><div>to one end & the wires are silicone sealed coming out the other end. On the T I have</div><div>a plug that I can remove to fill the tube & thruster with oil. This is okay for experimental</div><div>purposes but will need to add pressure to the system & a through hull fitting</div><div>when I mount it on the sub.</div><div>Alan</div><div><br><br>Sent from my iPad</div><div><br>On 3/10/2016, at 9:28 pm, hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px"><div id="yui_3_16_0_ym19_1_1475458034925_22070"><span>Alan,</span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1475458034925_22069"><span id="yui_3_16_0_ym19_1_1475458034925_22068">That is great! well done..

The propeller was a 3 bladed 7&1/4" x 4" with no kort nozzle.<br>I was getting 30kg (66lb) thrust from 30 amps off 52 volts (1560W) with the thruster<br>oil filled. This seems comparable to what Cliff was getting from his Minnkota 101.<br>The difference is this is a much smaller unit. I have been keeping a file on<br>performance statistics of commercial thrusters & trolling motors & this is slightly <br>above average.<br>The manufacturer told me not to run the motor more than 40 amps continuosly,<br>so I am being conservative with the 30 amp draw. I could bump it up by putting<br>on a bigger prop.<br>Next step is to use it as a boat motor & notch up 100 or so hours, then build<br>another housing with a mechanical seal.<br>Added a couple of photos to the project page, but they loaded upside down for<br>some reason.
