<div>I was thinking that they were the Minn-Kota size rigs.

I still want to throw an amp meter on each of the motors so I can balance the output to each. Rick, not a lot of expansion when you consider how much oil I have in the pods ! I have close to 8 gallons per pod ! Yes I know it's a lot but just as well, more heat dissipation and contaminants will likely fall to the bottom of the pod. </div><div> </div><div>Brian</div><div> <br><br>--- <a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a> wrote:<br><br>From: Alan via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>><br>To: Personal Submersibles General Discussion <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>><br>Subject: Re: [PSUBS-MAILIST] motor pod testing<br>Date: Tue, 3 Apr 2018 16:29:40 +1200<br><br></div></div><div style="font-family:Arial,sans-serif;font-size:10pt"><div>Hi Brian,</div><div>you should get a lot more cooling in the water.

Had about 8 feet of 1/2" vinyl tubing coming from the top of the motors going straight up into the air and hanging from my overhead I beams. Had the vinyl tubing connected to small inner tubes that had the air evacuated out of them. It was a cool day ( overcast, 60 degrees) . I ran the motors for over an hour, by the end of the hour the wd40 had climbed the whole 8 feet of tubing to the base of the inner tube. The motor pods were warm. If the sub had been in the water I don't think I would have had as much expansion of the oil. So I think that is going to work pretty good. Gives me a chance to run the batteries down significantly to see how my battery charger works with drained batteries, and how long it takes to bring them back up.</div><div> </div><div>Brian</div><div> </div><div> </div></div></div></blockquote><blockquote><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org" target="_blank">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote>_______________________________________________
