I finally seem to have fixed the problem I was having with belt-slipping. I mounted an angle bracket on each of the plates that comprise the motor mount and put a threaded bolt through one which then presses against the other to tension the belt (the plate the motor is on basically pivots). I don't think the tensioning itself is actually what corrects the problem - rather the whole thing is now "stiffer" because of the dynamic tension of the system. That prevents the flexing that was occurring under higher tension.
Happy sailing!
