in 11 years the guy put 670 hr on it. I was only worried that it didnt run enough. At least untill I met the mechanic . he fired it up weekly and did a run through of everything. The guy laughed about it.

Curious ?

11 years, 670 hours. Did the mechanic ever take the aftercooler off the engine and service it? Disassemble, clean and put it all back together with a good coating of marine grease where the dissimilar metals meet and then pressure test it overnight?

Remember, on the 6B/6C the bottom 1/3 of the cooler sits in sea water 24/7/365. An annual zinc change is not enough.

IHMO the "service" should be done after every 4th season regardless of hours. Helps prevent the possibility of the engine breathing highly compressed salt air. :(

Curious,

Can't tell you when and how frequently this was done without going through my records, which are on the boat. I will put a call into the previous mechanic today. All I can honestly tell you is , my mechanic( A diesel mechanic for 25 years) said it was extremely well cared for motor. He went searching through the 2 foot stack of papers to get some info. And said he has never seen someone so anal , and realy just silly overkill.

With that being said I am a marine diesel idiot. I do what Im told by the profesionals , luckily ive got a friend thats a very qualified diesel mechanics thats remodeling his house.
Im a contractor ,and now that he constantly needs my help, I dont feel like an ass asking for his.

I will let you know asap.

Excellent !!!!!!
Every now and then a poorly maintained aftercooler takes out a very good engine !! ALL preventable !!;)

What do you think you are burning at that cruising speed of 19kts? Anyone roughly know for that engine.

Do you know what is on there for a prop? Typical Dynaquad? Be nice to throw a DQX or better on there. This boat seems to be teasing me...

I drilled out holes with a bi metal 3 1/4 inch hole saw, aboat 1/8 biger than holder diam. Then sealed inner walls of hole completely with 5200 sealant , along with sealing screw holes. Before dropping holders into place ,I applied a bead of marine gasket sealant to back side of holder flange. Although I had a machine shop fab me som 1/4 alluminum plates to extend the load on top of the holders backing plates, In the end I felt the LD backing plates ( although strong) had just enough give for me to crank tight and they somewhat formed to the slight contour of under rail.
I feel the ability to form to the rail was more importaint then extending the actual plate. After all the holder itself is only as strong as the actual rail its atatched to.
