I am prepping my 29,000lb cruiser for a long distance voyage and am considering replacing my 25 year old Yanmar 4JHTE (5,000 hrs) with a new 4JH5E (non-turbo but similar hp to 4JHTE). Does anyone have experience with the 4JH5E? If I end up replacing, will the new engine be a "bolt in" (ie- how much modification, tinkering, etc). Would I be better off having a rebuilt 4JHTE in remote areas of the world considering its mechanical simplicity (fewer electronics=easier to work on....possibly more tolerant of crappy fuel?).
