Will a different gearcase work on my boat. Ebay has lots of them at a good price. If anything, I might be able to just take the driveshaft out of a different gearcase. ? ? ?





69 & 70 85 & 115, 71 & 72 85, 100, 115. The 85 will have a slightly different gear ratio, don't worry about it.
just to clarify:
1969 & 1970 are the years that the 85hp and 115hp are interchangeable?
and
the 1971 and 72 models (85hp, 100hp, and 115hp) will fit my 1970 motor too?

If you check the drive shaft P/N on http://epc.brp.com/default.aspx?brands=ej&lang=E&dealerlocator=no the only years your particular motor shares is 1970-71, 85 hp and up. I have no experience with interchanges of these parts, I can just read the schematics. There must be a reason for having different P/N's for the drive shafts. Remember "caveat emptor" when buying from Ebay. Nothing wrong with it, especially in your position; but just double check the interchangeability.
