Re: how often do you change your impeller?
I have changed my OMC Stringer water pump impeller 2 times since new in 1980. Each time the impeller look great. The first time the houseing the impeller runs in was pretty bad, most likely from salt water use at ramps that did not have a wash station. Second time every thing looked great but there to replace the spline short shaft so just made since to change it.
My 1975 15 HP Johnson Outboard has also been repalced twice since new in 1975.
Again the first time it needed it and the aluminum houseing was bad. I replaced with the stainless steel housing. Second time I was in there because I was changing motor from a short 15 inch shaft to a long 20 inch shaft. When your in there just makes since to change water pump and shaft seals. Second time I changed if I had not marked it with a red majic marker I would not have been able to tell the difference.
I never turn over either motor with out water.
