120 Force Outboard by Mercury
So I just bought this boat from a buddy and it has a 1996 120 HP Force. The problem is to get it to idle while it is in the lake... It will idle all day long on the water hose but when you put it in the lake it will not stay idling.. I checked the reeds and the reeds are fine I took the carbs off and cleaned them they didn't look bad at all. I put in new plugs but I haven't had a chance to take it back to the lake since I have done those things, so any ideas if I get out there and it is still doing the same thing?? Any help or advice would be awesome..
