Question about Boating
How to change a Berkeley jet pump impeller?
I own a 20 foot jet boat with a 455 cubic inch Oldsmobile engine. My engine's RPM's are norman (and even higher) but I'm down about 10 mph from 52 mph to 42-45 mph. I believe it may be my impeller that is starting to wear out.
This is a shot in the dark BUT check to see if there is a wear ring that would sit around the outside of the impeller.Its inside the pump but would be right where the impeller spins.Jet skis have them and I thought yours may also.Hope this helps
