Just want to say the guys over at Brandon Automotive are top Notch.Drove the boat over to Daybreak Monday and they pulled the motor out.2500 lbs of diesel was pretty heavy.Loaded it on the trailer and took it to the shop.Spent today pulling the motor down and removing the sleeves.Just like we suspected the O rings on the sleeves were completely gone.You could see where the water was getting into the crank housing.All i need now is a complete gasket set and O rings and will have it all back together.Everything looked really good other than the gaskets and O rings.Sucks having dumped so much into this boat and never really got to use it but at least Ill have 1 rebuilt motor.The other Motor runs like a champ but at least after doing 1 doing the other in the future wont be half as bad.Should have the motor back in and runnin like a champ in 2 weeks.Stand by for reports.

UPDATE.... Got all the parts cleaned up and ready for primer today.Took all day cleaning and using power brushes and what not.Got my price quote on the upper and lower gasket and seal sets including the O rings for the sleeves.300 dollars.I spent that on a replacement solenoid the size of 2 quarters on my old outboards and here it only cost me 300 for a complete gasket and seal set for a diesel.Am i missing something.People say that the bigger the boat and stuff the more money pit but my experiences so far is my old boat with outboards everything was tripple cost what it has been on these diesels.Ill take some pictures tommorrow and post em up.

Lookin good Will. Question:Are your engines raw water or fresh water cooled? Liner 0-rings don't just go,theres a reason why they failed. Cavitation in the cooling passages are notorious for o-ring failures and even corroding liners to the point of making holes in them.

They are fresh water cooled.use the normal heat exchanger.The O rings failed when the Motor severely overheated.The thermostats were shot.There was alot of little things that added up.I dont think the O rings have ever been replaced on the sleeves.It actually wasnt all of them it was one cylinder and the piston has some serious scars on it on the one that was leaking.Im replacing the liner and piston on that cylinder.I already acid cleaned the heat exchanger and cleaned the whole cleaning system.Replacing all the hoses and impellars and zincs also
