Flushing the cooling system
Cooling system flushing is essential to pre-
vent the cooling system from clogging up
with salt, sand, or dirt.
(1) Connect the garden hose adapter to a
garden hose.

the engine you are going to flush and re-
move it. Insert the garden hose adapter

and twisting it until it is securely connect-
ed.

(3) Connect the garden hose to a water tap.
(4) Make sure that the area around the boat
is clear, and then start the engine. Imme-
diately after the engine starts, fully turn
the water supply on so that water flows
out continually from the jet thrust nozzle
and cooling water pilot outlet. NOTICE:
Never turn on the water before start-
ing the engine. The water could flow
back through the muffler into the
crankcase causing severe engine
damage. Be sure to turn on the water
immediately after starting the engine
to prevent engine overheating.
(5) Run the engine at a fast idle for 3 to 5
minutes. If the engine stops while flush-
ing, turn the water supply off immediately
and perform the procedure again from
step 4.
(6) Turn off the water supply, and then drain
residual water from the exhaust system
by alternately pushing the remote control
