Yamnar 3GM Engine Info

Looking for information regarding a 1984 Yanmar 3GM engine, model tag on valve cover is missing, we have narrowed it down to what we believe is the 3T72HLE engine, can anyone tell me the final determination as to specifications or other ID type marks, numbers, etc.? If further info is needed please write. thanks in advance

Two things:

You maybe confusing the 3T72HLE number with the engine model. I am not a Yanmar expert, but my engine is vintage yours and don't recall theat number as a 3GM model. The 3 GM models that I am aware of are that 3GM30 and 3GM30F. One is sea water cooled and the other (3GM30F) fresh water cooled.

You could call a authorized Yanmar dealer and give them the serial number off of your motor and they would be able to tell you what you have.


If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
