Re: Have these Yanmar Diesels a good reputation for reliability

I may be making too big an issue of the model designation but I do know that many 4JH2 parts are specific to a single model.

A Yanmar parts dealer website does contain the note, under "Yanmar Engine Identification Help" that a (C) in the model number indicates the engine was intended for a saildrive application;

https://shop.toadmarinesupply.com/ma...entification++

The YanmarHelp website contains the same information about the (C) designation:
ENGINE MODEL CODES

I don't know what differences there are in a saildrive and prop shaft engine and it may be of no consequence but I sure would want to know before buying a boat with (C) engine connected to a prop shaft.

If its in a saildrive configuration, the engine won't be your primary concern, the saildrive will be.

Are you sure about this?
I have only had two new Yanmars and both came with explicit instructions on how to operate them during the break-in period!

That is what he told me. I have no idea for sure. He's been delivering boats for close to 30 years, but also liked to talk a lot. Could have been a rumor he had heard and just stuck.

Just realised this is your first / second post so a big welcome aboard to CF and hoping to hear much more from you in the future!

Or could be an excuse for hammering a new engine on a delivery

Anyway it might be true for some of their engines or it might be "new" thing but I wouldn't put too much faith in it's veracity in a universal sense

Yanmar assemble engines in various parts of the world and ship party assembled to various countries for final assembly and sale. For instance, some Yanmar engines sold in Australia are partly assembled in Europe (The Netherlands I believe) and final assembly in carried out here, some come direct from Japan (AFAIK) completely assembled. I dunno about the USA although some Yanmars sold in USA are from Europe - these carry an "e" prefix in the serial number.

So as you see, it probably isn't a universal truth and perhaps not true at all

Re: Have these Yanmar Diesels a good reputation for reliability

John Deere used to sell, and very well might still sell, tractors with Yanmar engines in this HP range. My 48 HP tractor engine is a Yanmar. JD should be able to get parts for at least some engines. My JD dealer was cheaper for oil, oil filters, air filters, etc than the local auto part store, so I would buy JD branded filters and oil for my Ford truck.

I would certainly compare prices for Yanmar parts at JD and maybe other tractor and equipment dealers.

Later,
Dan

I finally got a chance and go check what JD is selling today since I was curious if they had changed that much in 16 years. JD is still using Yanmar engines in the compact and subcompact tractors with up to 65ish HP.

Years ago JD had a less expensive tractor line that I think were built by Yanmar.

Later,
Dan

Re: Have these Yanmar Diesels a good reputation for reliability

Any early reports about the new Yanmar 4JH common rail engines? Have posted other threads.
Anyone know about reliability?
