I've only been around outboards before(and I only know the most basic things). I'm going to be looking at a 1969 Glasstron with an I/O. What should I look for on the engine?? Yes, I know there are the obvious things, but what else? Any advice would be appreciated. Unfortunetly I won't be able to see the engine running because the owner is in the 10th Mtn. Div., and his unit is in Afghanistan(his wife is showing me the boat, and she says she doesn't know how to start it.)
