I think I am going to chicken out on pulling my lower unit and trying to do some repair myself. I think I will call a mechanic and get an estimate. It is leaking water into the bilge when the outdrive is up and it stops when lowered. So, my plan was to remove the lower unit and replace everything that was rubber or considered preventative maintenance (like the impeller etc.) I know the information is vague, but that is all I know at this point. Can anyone tell me what kind of price range to expect to get rough estimates in?
