I wish I had as many choices as you do. I'm envious. Yes, actually those Honda 20's have the highest HP per weight, of any small four strokers on the market ! I'd almost go with one, except I want to go with the max HP, for my V-hull, plus it would be kind of strange to have a Honda motor on a Yamaha (G3) boat. Either way, I'm almost sure your mod-V with a 20 hp Honda, would blow away my deep-V with a 25hp Yamaha.

Peace,
Fish
