I think one of the very best motors you could get for your boat is the Johnson/Evinrude 3 hp. that began production about 1953 and the same basic motor was still oin production in 1968. These are a sweet motor smooth and easy to operate.Routine parts are still available some even at your local NAPA auto parts.(some NAPA branches don't know about their 600 page marine products catalog).You will pay more for these than say an Eska,Chrysler,Force,And some of the other off brands but you will be happier. In our area, Central NY,The J/E 3 sells for about $150 to $300 depending on condition.
