Doug King: Most of us like to look after our
boats. We polish them, wash them, change the oil,
have them serviced regularly. But what about the cooling system? It’s often overlooked, and over time, salt,
dirt, sand, mud, can build up and block the cooling system and restrict the flow of cooling
water. Flushing the cooling system on a regular basis
will ensure proper operation of proper temperatures, and give you longer engine life. Doug King: There are two ways to flush outboard
engines, the earmuff method and the built-in method. The way to use the earmuffs are to make sure
that they’re put onto the cooling intake firmly, and there’s no leaks. Plug the hose in, turn the water on. Wait till you have a good water flow, then
start the outboard engine and check that the water is flowing through the cooling system
by having a look at the outlet. After two or three minutes, turn the engine
off. Turn the hose off. Remove the earmuffs, and the engine has been
flushed with fresh water. Doug King: With the built-in system, engines
may have a connector where you connect a hose straight to the engine. The advantage of this is that you can flush
the engine while the boat’s in the water, or you can use it where you’re not allowed
to start the engine and make noise. To use this method, you just plug the hose
into the connector, turn the water on, leave it on for two or three minutes. The upper unit of the engine will be flushed. Then turn the hose off, re-secure the connection
on the engine, and the engine is flushed. Doug King: The key points for flushing engines
are, don’t flush your engine unattended. Always monitor the flushing process. Check that your cooling intake screens are
clear, and always check the telltale, to make sure that the water is circulating through
the cooling system. Flushing your engine, particularly after you
have been operating in saltwater, dirty water, or silty conditions, will ensure that your
cooling system is kept clean, and you’ll get a longer life and better operating temperature
out of your engine.
