Usually a plaque on the engine somewhere .. usually on the front gearcover ..

There should be a plate somewhere on the engine with the horsepower rating and model. There might be another one on the transmission with its model, gear ratio, and fluid type.

From the ~1987 general Hunter Legend owners manual... but considering the age, should still confirm the plaque in the engine... it could have been swapped at some point.

As i read the chart listed it say a 40 ft hunter should have a Yanmar 4 J H S E Diesel
I have tried to search for a manual an only come back with a Yanmar 4 J H 5 E Diesel

CAN IT BE THE SAME ??????

Don't think they are the same.

The JH family starts in the 80's... and has evolved JH2/JH3/JH4/JH5... with the JH5 starting in ~2010.

I'm not a Yanmar expert... but I think you'll be looking at 4JH-E manuals... I don't know why the "S" is there... perhaps it meant shaft as opposed to saildrive... don't know.

You really need to get a picture of the plaque on the engine to be sure.

sorry can't be more help!

As others have said - there will be a plate on the engine (somewhere). That is by far the most accurate way to find out exactly what you have, along with the serial number. For example - my 2009 Hunter 41DS has a Yanmar 4JH4AE.

Your transmission will also have a model and serial number as well. This is important to identify so you know whether it is recommended to keep it in neutral or reverse when under sail. And what kind of oil, etc ;)

In another post, you said it was a 3jh40 yanmar…


Have you looked at the engine?

You can also count the fuel injector lines to see if it is a 3- or 4- cylinder engine.
