A friend of mine has a Mercury Optimax 150 HP saltwater outboard 2000 model year and he told me he has never changed the impeller. I'm not really up on outboards, but I would have to assume that there must be a water pump impeller that should be changed every year or two.
Am I correct? and how diffulct a job is it? I change the impellers on my US Marine 454's every other year, and it's pretty easy.
