As I am now starting to put my Outdrive Back together in preperation for my new Sea Trials set for late August I wanted to share with all here the different parts I found and the year they were first or last used. This Sterndrive was attached to a 1974 SkipJack FB with a 1998 Mercruiser 5.0 Powerplant.

Now, if you had to tell some Mechanic or Parts House what year model was your Drive, what would you say?

Upper Gearcase 225 First Used 1972
Grounding Cable Upper Gearcase First Used 1972
Exhaust Housing Last Used 1971 Have since changed to Model First Used in 1976
Bearing Housing Extended Last Used 1970
Pivot Caps First Used 1975
Upper Gearcase Gears 21/17 First Used 1978. Have since changed to 21/16
True-Coarse Steering First Used 1974
Rudder Last Used 1971
Swivel Bearing Housing 2 Zirk Fittings First Used 1971

Tell them it's a Frankenstern-drive.

I would just give them the range year.. From my experience OMC seems to work from 1964-1977 for yours. So I would say yours is a 1972 with 21/16, what year is the lower?

The Upper Gearcase had a 21/17 on it and I changed it to a 21/16. The Lower Gearcase was changed out before I agreed to buy the boat. I still have it. It only has one Zirk fitting on the Swivel Bearing Assembly which was used in 1971.

Since it does have Tru-Coarse Steering which started in 1974, could a prior year Upper Gearcase be retro-fitted with it or is it likely the Uppercase is a 74-77?

Mongrel's make better pets than pure breds, according to my vet. :D
