    This is the water pump after removing the lower unit.

    The spaghetti ring seal under the cup.

    The old wear plate, notice the scoring on the plate. Time to replace it.

    This is under the wear plate and the old sealer was cleaned off and a new gasket was installed.
    I use a brush on sealer by perma and I can remove gasket later without much trouble but still have a good seal.

    New wear plate installed. I installed the impeller at this time but forgot to take a picture. You can see how the impeller
    comes off when you remove the impeller.

    This is the new cup installed over the impeller. You can wet the inside of the cup with a little grease or as I prefer
    I use dish washing liquid and turn the shaft clock wise and push down on the cup while doing this, it will slide right on.
    Some worry about installing the impeller the wrong direction but it will right itself the Minuit you start the engine.

    The O ring seal for the drive shaft. If you will notice the grease on the splines. You put just a little but not on the end of the
    shaft. If you put to much on the end it can cause a preload on the shaft and do damage to the motor.

    I am going to change on on a electric shift here in a few days and I will post pixs of it from lower removal to the end of replacing it.

    Hope this helps someone on here.

    Great job Willard.
    That will help out a lot of people. Wish you had took one showing where that nice easy bolt is to turn the shifter linkage loose. Now that is fun.
