Freshwater Flushing Attachment
Your outboard features a fresh water fl ushing system. After linking up
to a fresh water hose at the fl ush port, water can be pumped through
the engine’s raw water cooling system to fl ush out all salt and debris
that may be left behind. Normally there is a hose thread fi tting on
the side of the engine. After the connection is opened a garden hose
is connected to the fi tting and the engine can be fl ushed. It is best to
connect the fl ushing system up when the engine is warm since the
thermostat is open at this time to allow water to circulate through the
entire head rather than bypassing the cylinder head areas.
ENGINE ELECTRICAL SYSTEM
Your engine utilizes a great deal of electronic equipment. Some
equipment sends signals between the engine and the Garmin, while
other systems set off alarms, and still others are used by the engine
to generate a spark and ignite the fuel. The battery switch controls
electrical power distribution to the boat systems.
To regularly maintain your DC electrical system, inspect the battery
charge before each trip. Test all gauges and control equipment prior
to departure, and replace as necessary. Spark plugs should be replaced
according to your engine owner’s manual maintenance schedule.
When a fuse blows, investigate the problem before replacing fuse
