My Detroit's use Johnson water pumps. On this last outing I replaced my third impeller on my starboard engine in two years. That makes four impellers for the two engines in two years plus one for my Northern Lights generator. Replacement Jabsco impellers all except the Northern Lights which is a Northern Lights replacement part. Since this is the first impeller for the Northern lights in two years and the first I've installed I don't know the history of the old impeller. However I think I'm burning through the Jabsco impellers at a alarming rate. I'm using Jabsco as replacement as they are easy to come by. Has anybody got a better type or brand of impeller. I understand there are impellers made from a better rubber, has anybody had any experience finding better impellers?
