Just changed mine last week. This is my 2nd year with the boat and first time changing it but since it was so easy I think I will do it every year to be safe.

Hey,

I inspect mine in the fall as part of my winterization process. This past winter I saw cracks in the rubber at the base of the vanes so i replaced it. Since I motor about 50 hours a year, I figure I can easily get 4 -5 years from an impeller.

The impeller for my oberdorfer pump is about $50 by the time you add shipping and tax, so I feel that it would be needlessly expensive to change it every year.

I do carry spares with me, so I can change it if required.

I have never had to change the one on my outboard in the water and I don't intend to.

It's every year for me, buy a new one and install the old 'new' spare one and then put the new one in the plastic bag for next year or just in case.

Nothing, but nothing angers me more than things that break unexpected when they could have been prevented.

I say when.

Every 200 hrs, so that's about once a year.
