I'm not quite sure if this is the right section of the forum to post this question, but I would like some advise from the techs that work or have worked on a variety of motors and drives. I am looking to buy a speedboat for a restoration project. Anything from the 60's to possibly the early 90's. My question is what engines and drives(I/O or outboards)should I say away from? I know this is a very broad question but I figured there are enough people on these forums that I could get a good general idea. Any help would be appreciated. Thank you.
