Can anybody share a video link or shop manual link on how to replace the prop shaft seals on a dual prop 290 A2 outdrive? I've checked Google and YouTube and haven't found one. The manualslib.com site doesn't appear to have manuals for these older drives. I did find the write
-up below and it appears pretty straight forward, but I'd like to see a how-to vid to ensure I don't screw up the seal change that I'm contemplating doing myself. Thanks in advance.
"You need to take out the two hex bolts behind the round anode, then you can tap the bearing housing out of the leg, I use a paint scraper to get it started about 1/2" back here is a join, then you can get 2 screwdrivers in and work it out of the leg, the thin inner axle stays in the drive.
You pull the bearing housing of the outer axle and then you can remove the seals. The large outer seals just go in with the inner one facing in and the outer seal facing outwards, grease them well and pack the space between them with grease also.
The smaller inner shaft seals have a set of instructions with them, as the seals are different and the inner one only goes one way, grease these the same way.
I use a suitable socket to drift them in, a tip on reassembly is place the plastic bag the seals came in over the large outer shaft before you slide the bearing housing over it, it will protect the new seals from being damaged by the serrations on the outside of the large shaft, then pull it off when its fully on, you will see what I mean when its in front of you.
I always replace the 2 'O' rings behind the bearing carrier at the same time, grease them to aid reaasembly.
Then refit the bearing carrier complete with outer shaft over the long thin inner shaft and tap it home, rotate the outer shaft to make sure the gear teeth mesh or it won't go fully home and refit the twohex bolts."
