My son just acquired an older ski boat with an outboard Mercury motor on it and I have no idea on anything about the motor. I was hoping someone here could give me some advise. It is a late 70's or 80's ski boat. The engine is a Mercury 140HP. I know it is a two stroke, six cylinder. It is also marked Thunderbolt Ignition. The serial number is 3754838 if that helps anyone.
So I have no idea where to get any parts and don't even know what the oil ratio is. An internet search really did not help. Everything seems to default to a 150HP motor. If anyone can give me advise as to what model this is, where to find parts (Plugs, Impeller, ect.) and what the oil ratio is, I would really appreciate it. Oh yeah, it also has not run in about 5 years, but was told that it ran like a top when parked.
Thanks,
Travis
