Years ago I used an Evinrude 55hp two cylinder on a 16ft whaler. It had plenty of power, but was awful when I used it for trolling. It would vibrate so much it would numb your tiller hand. It wasn't miss firing, it was just because it only had two cylinders and was not smooth. I switched to a three cylinder 60 hp Yamaha Enduro and for the first 15 years it idled and trolled like a champ. Now though it is getting worn and tired ( I might get one more season out of it) I am now shopping for a replacement, weight is a consideration, so I am leaning toward a two stroke Evinrude, but if they won't idle down and troll I will look elsewhere. I don't see any around here in Campbell River, so I was hoping someone with practicle knowledge could let me know their opinion of Evinrude's e-tech two cylinder engines.
