    Impeller shaft replacement

    I am pulling my pump for maintenance. The ski has about 190 hours on it. I am going to replace the seals and bearings. Is replacement of the of the impeller shaft necessary if it isn't damaged? Everything turns fine and it doesn't make any noise.

    As long as the shaft is not damaged, there's no need to replace it.

    I tend to change it on a full pump rebuild specially on salt water the shaft has a tendency to flake off on the surface the seals ride on, cheap Insurance in my book .

    Thanks everyone. The manual says to run your fingernail on the shaft where the seal lip is and if it isn't perfectly smooth, replace it. I was just trying to get ahead on my parts order and didn't want to buy a $95 part if I didn't have to. Pulling the pump this weekend to inspect it.
