Yeah I think the 4 cylinders were about 120 hp. Look the boat over real good. One problem you will find with older boats is the transom or very back of the boat will rot out or the stringers in the floor will rot out. What happens is they get wet and then dry rot. One way to look for bad stringers is to see if the floor has any give or is spongey. If you can pull the drain plug on the rear bottom of the boat and the plug housing and see if the fiberglass is solid through the transom. You can usually put your fingers inside the hole and see if its solid or not. Just some things to look for.
