I am looking at a couple 27' Sea Sport Pilothouses. Both have the KAD 44. I have always owned gas boats, so the diesel thing is new to me. How many hours could one expect to get out of a well maintained engine? Do you guys have any comments for or against the 44? These are higher HP diesels, so I would expect them to have a shorter life than the slower turning, lower HP diesels, but what should I expect? I have always maintained, repaired or rebuilt gas engines myself, so I am a little reluctant going to diesel. The price difference buying a diesel/gas used in this market, doesn't seem to be as big of a factor as when they are new. The thing that IS appealing is the GPM difference. I realize that there is more maintainence and that diesel fuel is more expensive, but the diesel still seems more cost effective to run. Also, who would you suggest for a Volvo Diesel shop? Any comments would be greatly appreciated.
