The engines can be rebuilt in the boat. Its not easy but it is the normal procedure. I would not take them out unless the oil was milky or the block, crankshaft, and or cam shafts were bad. Granted if..... |

MDS thanks for you feedback. If the re-build adds up considerably, what would be a suitable exchange option i.e. cats, cummins etc without changing shafts etc? |

IMO, Cummins QSC 550 H.P.
You stated the difference in annual service costs in your area for Detroits and Cummins. Just that difference alone would save you 45000.00 in 10 years if accurate. Shaft si..... |

Did you adjust the idle when the engine was already at operating temperature? Does it always drop back to 450 RPM even after all your adjustments? Try checking the throttle linkage for anything l..... |

Yes, I did the ajustments at operating temperature, and it drops only after a quick run, if I drive the boat for an hour at 800 RPM through small lakes there is no problem all day. |

No idea how much room you do or don´t have but can you get at part of it with an Olfa knife or similar very sharp blade. I´ve managed a few times to start a gasket off by slicing part way. Then p..... |

Second Clark on the fasterners. There are some sneaky bolts near the flywheel end.
Otherwise, a thin stiff blade hammered into the gasket gets things going. |

Thanks guys. We did finally get it and to your points it requires a sharp blade that is strong enough to hammer. |

There are places to pry at all four corners, but a couple putty knives driven into the gasket is usually what it takes. If getting the pan down is hard, wait until you scrape the petrified gasket. |
