I have an M60 with just under 7000 hrs on it that is losing significant compression in 2 cylinders.It had a valve job done on it at about 4000 hours. About half the engine hours were in salt water. Is it worth rebuilding the engine at this point? I am concerned that if I rebuild the engine I have no way to know if the exhaust manifold is going to still be good. Right now the engine is losing significant power. If I do rebuild it, where is the best place to get parts? |

Palmer M-60 AKA P-60 is the IHC Cub Lo-Boy C'60 engine. Not CUB Cadet engine. If you have a good exhaust manifold go ahead and rebuild. If you don't forget it is my opinion. Don't talk Palmer to the tractor dealers as they won't know what you are talking about all the basic engine block was IHC and all Palmer stuff was bolt on. Note Palmer cast iron oil pan and adapter housings for reverse gear, distributor and water pump drive are all Palmer add on item. You can get complete engine rebuild gasket kit from Gaskets to Go in Thailand. John Baker does excellent work and very reasonable. Don't try to use the IHC tractor head gasket in salt water. OK in fresh water. Save all Palmer bolt on items for the rebuild. None of the tractor parts like carb, mag, fan, clutch, reverse gear, flywheel distributor, generator. Palmer used the basic block and head but none of the tractor related trim except for the starter. The valve cover was modified by Palmer to control oil flow in the PCV system connected by a plastic pipe to the marine carb backfire trap. The tractor dipstick unmodified provides the engine oil level and intake air for the PCV system. |

The real issue is what is the best diesel engine to slip into the spot of the old Palmer and just give up on it. I've got an Islander 30 MK II and it's getting about time. I just dread changing out the gearing, connecting the cooling system to the old input and output lines. Anybody know if a Kobota or a Yanmar will fit in handily. |

Is there any way without tearing the engine apart to verify whether the exhaust manifold is still good? I have been quoted about $4,500 to rebuild versus $10,000 to $12,000 to repower with a diesel. The palmer has been a good reliable engine if just a little under powered for the last 44 years. My Allied Luders in mint condition other than the tired engine. |

Scott, much as I enjoy helping people maintain their P-60s, I can't see spending the money on an overhaul. Beside the inconvenience of dealing with an engine that is out of production with no after market support for some parts, there is the lost if and when the boat is sold. You are at that point in effect selling a boat without an engine. I suggest treating yourself to a new diesel. You deserve it. |

Scott: In terms of possible replacements for your M60, I am helping the owner of a 1970 vintage Douglas31 to replace his old M60 (i.e.P60) with a diesel motor. When launched this spring the boat sank alongside (freshwater) when the engine cooling water intake hose let go overnight at the through hull fitting. At this time, after some looking around it looks like the owner and the marine engine mechanic hired will go with a Beta Marine(www.betamarine.co.uk) diesel purchased through a Canadian supplier -(we are in Hamilton, Ontario). Delivery is quoted at 3 to 6 weeks and the manufacturer will supply custom motor mounts for a small fee. See website for info on these motors. We have no experience with these particular motors but the price is reasonable. Likely the prop shaft will have to be lengthened which is no big deal.
