For Sale: Yanmar 4JH-DTE $3000 obo

[Donahue]

Located in Yarmouth, Maine

Hours 5200ish (will update with the exact number)

77HP at 3800 rpm

Kanzaki KBW21 transmission

Has the Type C (I think) panel with tach and idiot lights. Wiring in one piece.

I removed this early 90s Yanmar from my boat today. I was going to rebuild but even the cost of peripheral rebuild and repaint was approaching a new Beta.

This engine was installed in a boat I purchased last winter. I had the engine surveyed and an oil analysis performed. It ran very well all summer over 100 hours or more. Starts immediately. Cruises happily and quietly at 2200 rpm. However, the turbo is a little stiff, the transmission appears to slip a little going into reverse, and there is more than normal smoking at startup (I think due to the stiff turbo). The mounts are also toasted.

So... I'm moving on. But this is a great engine for sometime with the time and skills.

If someone local buys, a good place to have the machine work done is Nasco Automotive Machine in Saco. They did the head and block for my 4JH2E (8000 hours) and I have been happy with the results, 1000 hours later.

That's good to know, thanks. I was going to go with casco bay diesel but good to know there's another good shop around.

Here is the oil analysis. The other one was for the transmission--showing some wear consistent with the slippage in reverse.
