Re: $6,600 to rebuild Atomic 4? replace/rebuild
Have the A4 professionally rebuilt and professionally installed. Replace all the extras: alternator, starter, cooling stuff while you are at it. $6,600 is on the plane of chump change for re-powering a34 foot boat. Going to a new diesel would be three times that amount. I do not think you would get back even half of a diesel repower, but would get back most of the A4 repower (its just not much money...).
