    1991 FS 175 shift shaft seal help

    I think there is an o ring that seals the shift shaft but the problem is getting to it, can anyone tell me how? Thanks

    You need to remove the shift rod housing. There are actually two O rings there an upper and lower. To install them lube the outside and inside with TCW-3 then lube the shift rod with triple guard grease.

    Im sorry guys, the lower unit (i was told) is a 96 150 FS, the original lower unit seized up a couple years ago so i bought a used one. I have the shift rod disconnected and the housing removed, but there seems to be a brass cover over the o ring, how do i remove that, or do i need to. Thanks

    Flip the housing over you'll need 2 318372 O rings $1.00 each.

    You'll need to make a "puller" out of a piece of coat hanger to reach in behind the O ring. By bending and grinding the end of @ a 6" piece, you'll get it out. It can be tricky so hang in there.

    I wondered what those fat little o-rings were for.
