yanamar 6lp-stp engine - pistons frozen - turbo rusted - everythign else works

Description

the engine had 1250 hours on it
ran great
i have a 2000 sunseeker - and one day, the middle engine alarm went off. all the guanges were good, so i shut it down, and ran with 2 engines for the day
turns out, i was supposed to close the sea cock, as the water went in through raw water, and back up through exhaust, and into 5th cylander, and when i went to start it, bent the rod (found out in hind sight)
and when the mechanic took it apart, he left the injectors out, after he tried to spin it, and it didn't (bent rod)
and then all the cylanders rusted up, as it took a while because of people not doing what they said/agreed
and so by the time i got the engine apart and saw the bent rod - the other cylanders had rusted also.
Was going to try and sell it as is
and if not, will strip it of parts and sell those seperately, and sell/scrap the core,core of the engine.
Is currently at the yanmar dealer in Ft Lauderdale - as he took it apart.
