can anybody recommend a 15hp outboard that is good . I looked online at tohatsu , mercury, evinrude , Yamaha, and Suzuki. it seems the Yamaha and evinrude are carb motors if that is bad or good?it looks like several of the companys are made in the same factory in japan for what I see online but who knows? can anybody recommend one brand over the other as I am looking for just a tiller motor with a 15" shaft, a 4 stroke motor, manual start. it will be use mostly fresh water and maybe a little salt water . thanks kully
