That is right, Minn Kota nor Kipawa do give figures. I mailed Kipawa for info so sustain their claims but the only thing they said was that a 105 increasy in speed could be expected. That proved to be true.
When I had both props I measured the angle at a given diameter of the propblade and did some calculating.
The info on Torqueedo came from their publications as any serious company should do.
I also try to avoid any carrepairshop where they would not let me enter there workplace, you should never heve something to hide. And when customers watching make you nervous you are not sure of yourself.

You're right that it would be nice to put the resistors in the pod where they are cooled by the water. The problem is that you would THEN have to add relays to switch the leads, or at least run extra wires down the tube.If you did a "full out", "med", and "slow" speed, you could then just have two resistors in the pod. The motor would have a neg. terminal, and the pos. terminal would go to the two resistors in series, with taps running up to the control handle. This would just give you two additional wires up to the conrol head. Is there space in the pod for two resistors?I saw the web page for Kipawa props - but don't see any specs for them... Is there a page anywhere that has specs for the Kipawa props?
