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.
