Renovation OM 606
A few questions. Are using the boat in fresh or salt water? If salt, that aluminum exhaust manifold will be very short lived. Also, did you keep the engines cooling separate from the sea water cooling loop? Did you add any sacrificial anodes to the engine?
I don't know what alloy the 606 pistons are but typically marine diesels use hypereutectic pistons since the engine loads tend to produce greater thermal transients than standard pistons can tolerate- possibly causing clearance/longevity issues. The thermal loads on marine engines are far greater but are easily dealt with since there is an abundance of cool water around a boat to dissipate the heat. Heat exchanger design becomes very important though. Most (not all) marine turbos are water cooled. Overloading a marine diesel is easy and is the leading cause of premature failure.
There is a great website - (boatdiesel)- (I hope this doesn't violate any site rules??) but there is/was a resident expert there named Tony Athens that is likely the most knowledgeable marine diesel guy I've ever seen. There is wealth of information on properly setting up a boat and marine engine and I highly recommend a lot of reading before going too far. Tony has many articals on the site most dealing with maintenance, exhaust design and NOT killing a good engine by overloading. He's a Cummins guy but knows all marine diesel engines and has likely forgotten more than I'll ever know on the subject.
I found the manual in .PDF. Send me your email address and I'll email it to you.
