I have found the answer. Globe impeller is BRC-06541!
Mind you this is for the o-ringed impleller.
Why the Globe? Well to get to my impeller:
1. Remove the stairs from the boat
2. I have to drain the anti-freeze
3. Disconnect the water
4. Remove the water
5. Remove the water pump
Now I can change the impeller. Only to reverse the whole procedure when putting it back on.
The regular impeller lasted 2 years without taking a set, so by upgrading to the nitrile, I might be able to streach that to 3. (I notice the difference in water flow as the impeller gets a set.)
I wish I could make the engineer
who designed the engine
compartment show me how he expected that to be done!
