I'm amazed at the disparity of replies to this thread. It seems that everyone has a unique POV on the history of the Yanmar inboard power for the J30. It would be a great project to research this from
J/Boats, and post the engine model spec for each year/ hull number to the class page.
Anyone want to place odds on finding this easily in the
J/Boats production archives?
I just purchased hull #517 (1985) and have no idea which power plant it has. I have a hold back on the purchase price, awaiting sea trial of the diesel, so the diesel subject is of some interest to me.. any recommendations on what I should look for specifically when powering up in the trial? (I'll have a yard mechanic on hand for this)
