Trying to identify our motor.The pan has 2TM15 stamped on it.It does not appear to be a 2GM as I originally thought.Pushrod length's are 6.42"+\-.
Is this a marinized tractor Yanmar?
I had a boat with a tractor engine in it and I really can't say I could tell you the difference except that in the older boat (which I own now) the engine is cooled by salt water - most of the parts look the same. The boat with the older engine is still running after 25 years at sea. It's also a 2 cyl.
