Turn on the garden hose all the way, and wait for water to come out
of the exhaust pipes.
Start the engine corresponding to the valve you just set up to flush,
and run the engine (at idle) the desired time to flush out the engine.
Continually monitor the engine gauges while flushing to verify engine
temperature.
When finished flushing, shut down the engine first, and then turn off
the garden hose. Return the engine flush valve to the run position
(turn the ball valve to the off position, perpendicular to the valve
body, open the gate valve by turning counterclockwise).
Repeat the procedure for each engine.
Make sure that you return the flush valve to the run
position as described above. Failure to do so will result
in damage to the water pump, and may cause severe
engine damage.
Remove the garden hose from the fitting, and re-cap the fitting.
Battery Charger:
A battery charger is used with shore power while docked, on the
trailer, or on your hoist. This unit will keep your batteries charged
and monitored while the vessel is shut down for a period of time.
This unit is located inside the mechanical access or in the engine
compartment of inboard powered boats. Refer to the quick reference
drawings for the location of the charger. The battery charger has
indicator lights to show low or full charge.
With the boat attached to shore power, or with the generator running,
turn on the BATTERY CHARGER breaker on the main AC/DC panel.
