I have a M-265 from 1969 (serial#46812 9). The engine generally runs well but lately I have some smoke and unburned oil in the exhaust. The shop that has worked on the engine in the past says it probably needs a ring job and complete overhaul, but no parts are available so there's no point getting into it.
Is this true or are there parts available out there somewhere? |

This is actrually an Internatial Truck Engine.
Parts should still be available for the basic engine. However Marine stuff like the manifold are very hard to find. If your engine was used in fresh water or was fresh water cooled it should not be an issue to rebuild it.
There is a manual available on Marine engine.com with IHC refrences.
It is located here.

Joe here is free advice and you know what that is worth. Palmer converted IHC truck engines for marine purposes very sucessfully as the engines were really IHC manufactured and Palmer simply bolted on the parts they designed and made or had made to convert to marine operations. The critical items today are the exhaust manifolds. If they were fresh water cooled and not rusted out the engine is a good candidate for rebuilding. For example you could possibly get a rebuilt IHC short block from Valu-Bilt tractor parts. WWW.VALU-BILT.COM Save all your M-265 marine parts to bolt up to the IHC rebuilt block.
Keep in mind that Palmer supplied cast iron crankcase oil pans not the steel truck engine pan so don't lose your marine parts. Watch out for the method Palmer chose to drive the reverse gear. Make sure the crankshaft is identical on both ends with the truck crankshaft if not use your marine engine crankshaft in the rebuild. The point I want to make here is in the case of the IHC CUB LoBoy tractor conversion the marine crankshaft was ground on the end opposite from the flywheel/ring gear to take a spline to drive the reverse gear. The crankshaft was a standard crankshaft and any crankshaft grinder can regrind that marine crankshaft and it will bolt right up in a new or rebuilt Cub-LoBoy tractor block with all the standard IHC oversize bearing inserts fitting perfectly. I am not familiar how the M-265 crankshaft mates with the marine reverse gear but that you could easily figure out once you have the engine appart. It may be like my 455 Olds which I converted in 1973 to marine operation in that you just used a Barr bell housing and bolted the drive damper to the flywhee/ring gear and then bolted the reverse gear to the bell housing. Didn't even need gaskets. Starter bolted to the bell housing and I used the steel crankcase oil pan plus Barr engine mounts on the forward end of the engine.
You could even have a IHC engine rebuilder take your old block and if it is fresh water cooled basically have a new engine when you get done. I don't know if the pan gasket for the cast iron pan is different from the truck steel
pan but I suspect it is the same as Palmer tried to make as few changes as were absolutly necessary. By the way Larry I understand from my son Jon who is an IHC truck engine parts guy IHC has gone back to the IHC name from the Navistar name. Thats all I know about the name change. The places to look for IHC parts are the truck parts people and the tractor parts people. They are both IHC but check with both if you run into trouble with part/gaskets ect. In anycase it will be a rare IHC guy who ever heard of Palmer so don't talk Palmer talk the IHC engine model. And that is my short free advice. Have at it and good luck. Think IHC. No I don't own any stock in IHC and remember all IHC truck parts dealers and all IHC tractor parts dealers are not necessarily colocated or even have the same owners |

Recieved from Joe for posting:
quote:Richard and others-
thanks for your help.
Yes, the engine is fresh water (coolant) cooled. What is the IHC engine I am looking for? Is it IH Cub LoBoy?

It is not repeat not a IHC Cub Lo-Boy tractor engine. That is a 4 cylinder about 20 Hsp engine that Palmer converted to a marine engine. I only mentioned it to point out that at least in that one case there was a slight change in the crankshaft. What Palmer did on the truck engine conversions I have no information. Perhaps Larry can help you nail down which IHC block the M-265 used. |
