Parts Help Needed

[jpock1976]

Update for pinion shaft in case someone else runs into this. While i was looking for part 909121 i found an image that specifies the difference between 909121 (M suffix) and 907738 (A11 suffix). Its attached. I pulled the lock nut and gear off of mine to compare. Mine was actually the A11 shaft. Lucky me. Lol so now i have discovered my model number as 990232A11 but still havent found it on the boat. Lol. Parts are on the way! Thanks again all!

The shaft with the short splines has a centering cone that had a press fit to keep the gear stabilized. All replacement gear sets came with the updated cone feature. The higher HP models were actually causing the splines to shatter. This was a running change sometime after 76. The seal surface on the pinion shaft is a chrome ring bonded to the steel shaft and sometimes rust will crawl under the ring and cause the seals to leak.
The seals are to be installed after the shaft is torqued to around 100 ft.lbs. An old water pump shaft can be used as a holding fixture. Without the seal guide tool you have to be careful to not reverse the seal lips when installing over the shaft. The seal installing mandrel “squares” the seal in the housing so just be real careful to get them as “square” as possible. If you are careful you should be able to get it right.
