Re: Engine Repower for Super Maramu

I cannot speak for the 4jh4hte  - just the 4jh3hte.

Getting the components is easy, If you have a 175 amp alternator it is already isolated.


The time to change over the engine to an isolated ground should take less than a day if is wired similarly to the 4jh3hte.

Yes, Bill.  110 HP 4JH4HTE.  It was hard to find a mechanic/electrician who understood the issue.  I posted a schematic in the files section of the way it is done.

it can  be modified, but is a lot of work... or you can order an isolated version still.

For those of you who installed Yanmar engines, were they able to modify their standard engine to use an isolated ground return?
