Just wondering if this is a good Motor or not. I think it is a 1981 model. Is it easy to find parts for? It is a straight 4 cylinder. It runs smooth with the muffs. How warm should the water from the pee hole be when running it with the muffs? Go out on the boat this weekend for a test drive before buying. What should I look for to make sure there is no hidden damage with the motor? Sorry for being so stupid about this I just want to make sure I don't get screwed on the buy.
