Rebuilding gearbox on 60 HP...issues with parts

Hi,

I have a 60 Hp Chrysler where the lower end had water in the gear oil. I want to rebuild the lower end, but I am having trouble with part numbers. It is a 609HA, which i understand would have been built between 1974-76. Its gearbox is a one-piece casting and the seals, bearings and one pinion gear needs to be replaced ( as well as the impeller of course). It seems like this 60 must have been a low production run, as it hardly exists on catalogs.

Any advice on how I might find what the parts numbers are ( eg is the gearbox equivalent to 55 HP number XXX, or 75 HP number XXXX ????? ...and does an exploded view of that box with part numbers exist somewhere?

The 74-76 60 IS a rare one!!!
The lower unit from the 55 is the same as the 60.J

Thank you Jerry...that info should make life a little easier!
Wondering about the top end...which parts will match that...is it a tuned 55 or a detuned larger engine?

I'm sending you a P.M.

The parts are usually the same until the carb jets. Maybe the bore/stroke. Have to know serial#s? Try looking at boats . net and entering your and compare to the other motors. Good luck.
