Question for those who have been there and done that. While inspecting pump impellor on 12JG pump I noticed a very tiny amount of movement of the inducer impellor on the shaft. Tiny as in being barley noticeable. I was told the pump was fresh when I bought the boat late last year. Boat is used mainly for pleasure. If I understand correctly the pump impellor seats against the inducer impellor, holds it against a shoulder on the pump shaft and is driven through a key. Any thoughts as to next step I should take?
