Thanks Mark. Yes, I believe that there are many different parts between the 3jh4 and 3jh5 models. When ordering parts one needs to know they are the correct ones. Sometimes we are away from Internet
contact so a copy of a parts catalogue for our engines is an important resource to have on the boat.
I'm really surprised that this sort of basic information is not readily available or was even supplied at purchase
. Especially as spare parts are sooo expensive. Perhaps Yanmar
don't want owners to order parts? Just find a service
agent and say "fix it".
It seems to me that the small marine diesel
industry, read "Yanmar and Volvo" are using the same business model as do computer printer companies; sell an engine at a competitive price
and then hope to sell subsequent products ie. Spare parts and service
items at huge markups.
