Have these Yanmar Diesels a good reputation for reliability

[Cheechako]

I might wonder why it had to be rebuilt already...?
Is that engine a turbo? I have seen complaints on forums about those.
Pretty much all marine diesel parts are expensive, not just Yanmar.

There is no Turbo in the picture, and I assume 600 hours since overhaul, but I too wondered what tripped the overhaul

I bought my 4JH2ce new three years ago so there is no way of telling just by the model number what year it is. As far as reliability goes, they are about as good as it gets.

[a64pilot]

Serial number and call a parts house will get you the year, I believe.

The Yanmar 4JH2E were built between 1989 thru’ 1999.

I have owned 2 yanmars...a 2gm20 in a C&C27mk4 and a 3gm30 in a Hunter Legend 35.5. Both were excellent. Very solid and reliable. Yanmar is my preferred diesel. Yanmar dealers and parts are readily available in my part of the world (Canada). I can't speak about cost of parts, because I never needed anything besides filters and spares (which came with both boats).

I've owned two atomic 4 engines, a volvo B2002, and a bunch of outboards. Yanmar is the best.

I have two 52 Yanmars on my Leopard. They are quiet, efficient as to fuel, simple, and have been very reliable. They both have over 2,500 hrs. on them. They are the best as far as I am concerned. I would count it as a plus on your boat purchase! Have a nice day. Hector

This is great information! I just joined the forum a couple weeks ago....love the daily emails and I have learned so much! Thanks Chuck

I have had a Yanmar 4JH HtE Turbo, 66 hp on my sailboat c. 1989 and have 3300 hrs and it has been very reliable. Had to replace a water pump because the boat yard said it leaked? Replaced a Hitachi alternator last year. Bought it from an alternator shop for $156.00 whereas Mack Boring wanted $900 for it. I've found the most expense of the engine is the mechanics working on it. It's not a real complicated engine, but when you have mechanics charging you for travel to and from at the rate of $105/hr driving time...it will add up. You can also buy parts from Torrenson Marine in Michigan if you live in one of their authorized states they can serve. Would not have another manufacture in a boat if I had a choice.

Do you have any reason not to think the engine is the same age as the boat?

Any receipts or proof of rebuild?

My experience with Yanmar's has been fantastic. I have had such a good run out of mine I never really needed parts other than filters and water pump kits. And I have never had trouble getting parts anywhere in the world .

As for parts, with minimal effort you can often find the cross references for many common spares (ie. Starters, filters, water pump, impellers, etc) on other applications (and often non-marine) at significantly cheaper costs. For example, I bought a replacement Hitachi starter for about 1/3 the cost of the OEM part as they share that part with engines used in some Tohatsu and John Deere heavy equipment. That said, I'm not sure you'll find that Yanmar OEM parts are much differently priced than many of the other main marine engine manufacturers. Have you priced out Volvo parts lately?

Walking away from a potentially good boat because you don't like the potential price of an engine part doesn't make a lot of sense to me if you step back and look at the big picture.

Just my thoughts....YMMV

Agreed !! I've had a Yanmar 4JE for nearly 20 years and it has been extremely reliable both in Canada and the Tropics. I change Oils and Filters regularly and only repairs has been new starter motor, new air cleaner, new water pump">raw water pump impellers, new raw water strainer insert, new alternator, new coolant pressure caps.
Parts were always readily available in NA and Caribbean and I always used Yanmar Parts.
I did however remove the Turbo Charger when I first purchased the vessel figuring that if anything was to fail it would be the Turbo. Reduced HP from 65 to 46, but still able to obtain hull speed of 8.6 kts.
IMO Turbo's are a marketing gimmick.

The Engine Serial No gives the Year it was Built and the HIN gives the year the boat was built.

We are on our second Yanmar (4JH4-TE) and we are very satisfied, with the reliability, fuel economy, and parts availability. Granted, we are in the USA so maybe the parts are more available. I do not have any specific information, but I would bet money that in the past 15 years Yanmar has been installed in more sailboats than any of the other engine manufacturers, combined.

I've had a Yanmar on my LN35 since 1986, never a problem...bulletproof,and parts are not a problem here in the US
