Hi everyone,

I did a survey on an older Hatteras 53 MY, and the engines showed "Blow By" (both), with increase in Crankcase pressure on both sides also (3.25, and 3.37).

Additionally tons of other things, but do these signs above mean Overhaul?

And if not then how do I go from here?

The port and Starboard engine cylinders were found to have minimal scuffing and scouring, cross hash marks are present. The surveyor told me that it means the engines have long way to go!

No compression test performed. he said that would be extra $$$.

The sleeves of few turbos were producing smoke on wide open throttle inside the engine room.

They have around 2300 hours.


Thanks for the advice. I appreciate your help. I am lost here.
