Re: Going from salt water to Fresh water
agree that you should replace the impeller -- and check the housing for possible replacement as well (corrosion damage). It's also not a bad idea to replace bolts as you pull them out. I'm not suggesting you get paranoid, but salt water corrosion is an amazing thing. You still need to flush the motor to get out silt and debris (sand will destroy an impeller quicker than anything else) -- and rust is still an issue. If you trailer, make sure the wheel hubs a greased (bearing buddies are good at keeping out water and making it easy to add grease).
