RE: Johnson 4hp Impeller problem ? There are many different model 4 hp motors over that last 30 or so years. Some have a water "tell-tale" stream and others just mist water out of the small exhaust relief holes in the back of the midsection, just above the gearcase. As long as the motor is not getting hot, you should be OK.
The small motors have shorter life spans on their water pumps than the big motors do. IF it's been more than a few years, it's best to replace it before it comes apart at the wrong time and place. |
