I have currently just purchased a new boat with the mercury 90hp engine ( 1996) 6 cylinder and have since discovered it seems to be running on four cylinders only , it is off the last two cylinders 5 and 6 ! i have checked the spark plugs and it appears to be getting a spark ?! Anyone any ideas !! please help !
