    Differences between Polaris through-hull bearing assemblies

    What are the differences between the older 1341115 (1993-1995) and the newer 1341145 (1996-2004) through-hull bearings?

    Is it just the grease nipple, or are the seals/bearing also different?

    If it is just the grease fitting, can the
    1341115 needle type grease fitting be easily changed to the standard Zerk fitting?

    The 1341113 is listed just for 1992. Is it different again?

    I know the MSX through-hull is completely different.

    The older ones have the seals crimped in and are made from a casting. The newer ones you can replace the seals and are made from billet. Both you can change the grease fitting it is a standard grease thread.

    I thought that was visa versa? my 92 had a billet unit but one I scored later is just a crimped steel tube

    I was recently told that the early drive shafts were a smaller diameter where they went through the bearing/seals, and so are not interchangeable with the later years (post 1995).
    Edit: Apparently not - drive shaft seals are the same inside, but outside diameter differs a little. The older version is bigger around on the outside.

    Sorry...the info given to me was wrong...like that's never happened before...they are all the same size dia. opening and will work on your watercraft drive shaft. I just took one out of the unopened part bag to check the size. What is a little different is the outside dia...they are a little bigger so the plastic shroud on the newer models don't fit perfectly but can be made to fit...and the flex tube that fits on the other side of the housing will be a little tighter/snug to put on at first.

    You are likely correct as I assumed again
