OT: orange, I hooked a 17 lbs thrust trolling motor to my 5000 lbs sailboat several times last summer to move it around (when it wasn't windy).
My boat has an INBOARD 2 stroke (sail drive). And I hate it too. Hatehatehate. I'm either going to get a more powerful troller, convert an outboard, or convert the saildrive to electric.
