    I need to replace my bent prop shaft, or at least remove and have it straightened, but for the price I think I will just go new. I've worked on top ends, but never done anything outside of a water pump or gear oil change on a L/U.

    What am I in for? What seals or parts do I need to replace while I'm in there? I have the service manual but I dont know what should be done as precautionary, "while-you're-in-there", type of stuff. Motor is a '92 Mariner 9.9 2 stroke.

    Thanks

    I like aluminum props just for that reason----u really have to hit rt. to bend the shaft on an alum.

    try bending it back straight with a pipe over the propeller shaft. May be a bad idea, but theoretically it should work. Worst thing that could happen is you have to get a new propellor shaft, and since its a 20+ year old motor changing the bearings and seals will probably be recommended.

    If you haven't already, search through youtube for some vids. I recently replaced lower unit seals on a couple big motors and it wasn't so bad after watching a couple of those videos. I've never done it but from what I've read, pulling the prop shaft seals and prop shaft are a higher level of difficulty for sure, with the motor being 20 years old. If you don't have the special tools ingenuity will be required.
