Good morning everyone well here is another question you guys. I have a 1985 140 hp johnson that is finally on the water and running great thanks to so many of you guys helping me. Well here is another on for you. Had the Boat out on the lake for the first time ( out on the lake !!!!!!! so pumped) It was running great, peeing water,just perfect,i was told to change the impeller at least every 2 yrs. I was just wondering how you can tell if its the water pump or impeller. The reason im asking is just a few feet from the dock the alarm went off and stopped peeing. I was going to change the impeller after I knew it was worth fixing since it has not run in 2 to 3 yrs. Should I put a water pump in or would I be safe just putting the impeller on. Money is getting low and the wife is getting, well you know.
