Randy,

Are you loosing these impellers do to lack of water?
Maybe it is time to put in a manifold with a check valve for all the times you are flying through the air. You would have more of a buffer instead of running them dead dry as soon as the boat leaves the water...

We ran such a system on our triple engine outboard cat. The manifold kept water pressure to all 3 engines, even if one or two engines weren't picking up water from it's gearcases.

I don't know what your rules state in regards to water pickups.
But I can see a hull mounted pick up with a manifold and check valve maybe fixing your issue....

Do you know any plumbers ???

Another thing to look for...Casting slag in the housing. We have found in many of the housings, enough sharp edges to tear up an impellor instantly.
