OK, so I am not a good negotiator, but I will just walk away at some point. I also don't like to needlessly insult people that I don't know. This guy has had this motor, I guess in the boat, for 40 years. I have no desire for a boat.
I'd like to get it cheap, unless I see any of the usual red flags. Then the price drops dramatically. I'm wondering if it's ever been apart???
Boat issues: They see high RPM, especially when they go airborne(flat bottom boats). Also constant cold water supply can lead to cracks, you won't know for sure until you disassemble and mag it. Small cracks at valve seats is typical
