[Electric Boats] Re: Torqeedo prop on Minnkota 30?

Fairing the downshaft will help.
Installing an anticavitation plate coupled with running the motor shallower will help.
Installing a three blade prop and turning it down about 1/8 inch at a time until you quit gaining speed will help.
My Prindle 16 achieves 4.3 mph by GPS with these changes.

I've got a Minnkota 30 here that performs in a mediocre fashion with its standard high thrust prop on a 2 man 17' kayak, or a 17' Harpoon 5.2 sailboat, and only marginally better with a Kipawa prop. Assuming it could be adapted mechanically, I guess the issue would be the motor designed for high rpm, high thrust being used in a lower rpm application. Might be interesting to try, though! (If I could get 1/2 to 1 mph more at same amp rate without burning out the trolling motor I'd consider it a worthwhile improvement for the $75 prop cost.)
