Re: [Electric Boats] Trolling motors ==> electric outboards

 

Ya, I wish these people would cut the "#s of thrust" nonsense and
tell us the watts, or at least volts _and_ amps so we'd have some
idea and a basis for comparison. I think they want to hide it from us
so we don't realize how little power they have.
