Hello, my name is XXXXX XXXXX I will be helping you today.


I do Yanmar engines and here is what I can tell you. If you shorten the numbers you gave me of 4T954E-SM to just 4T95, 4T95 is a Yanmar tractor engine. For like a Yanmar YM7000 tractor. These are agricultural tractors, bigger ones, like Yanmars version of a John Deere. And they are older, late 70's early 80's engines.


Whatever your looking at is one of a kind. And somebody pulled the engines out of an old Yanmar tractor, did lord knows what to them, and stuck them in a boat.


Other than that, did you have any questions about them? (I would probably pass on the boat, it already sounds like it would be a headache/project)


I already knew they were probably tractor engines. I did however give you the wrong model number, it should have been "4T95LE-SM". "L" instead of "4".

I already knew they were probably tractor engines.

You didnt' say that to me. And you didn't mention that in your question.

What is it you want to know then? I don't understand.

Would you prefer I see if we have any tractor mechanics here?

I suppose a tractor mechanic may have more info. Yes.

Okay, I will see if I can get this sent to a tractor category.
