2: Flushing an Outboard, How Water Gets into Diesel
What is the proper
method for flushing out an outboard? H. L., via e-mail
Open the water tap partially, shift your engine into neutral, and then start it, keeping it running at idle speed and no faster. Adjust the water flow so there is a slight loss of water around the rubber cups of the flushing device. Check your engine’s “tell-tale” nozzle to make sure water is being discharged. Flush the engine for at least five minutes to ensure it is completely clean and free of dirt or silt.
If you operate your outboard in salt water, you should flush it out after each use to prevent salt and deposits from accumulating inside the engine.
more water than usual in my diesel fuel/water separators. Where could
it be coming from? D.N., via e-mail
A second source is the fuel itself, which may contain water as part of the normal refining and handling process. Check with your dockmates, and if anybody else has the same problem, notify your marina manager.
Finally, water may be leaking into your fuel system. Be sure to check your filler cap and fill-pipe connections for watertight integrity.
