Cooling system flushing is essential to
prevent the cooling system from clog-
ging up with salt, sand, or dirt.
1) Open the cap for the engine you are
going to flush. Press the flush kit
garden hose adapter into the flush
hose connector and turn until they
are securely connected.
2) Start the engine, then immediately
turn on the water supply fully.
CAUTION:
Never turn on the water before
starting the engine. The water
could flow back through the muf-
fler into the crankcase causing
severe engine damage.
Be sure to turn on the water
immediately after starting the
engine to prevent engine over-
heating.
3) Run the engine at a fast idle for
10~15 minutes.

4) Turn off the water supply, then drain
residual water from the exhaust sys-
tem by alternately pushing the throt-
tle lever up to half throttle and back
for 10 to 15 seconds. Shut off
engine.
CAUTION:
Never have the water on when the
engine is not running. The water
could flow back through the muffler
into the crankcase causing severe
engine damage. Do not run the engine
for more than 15 seconds after the
water supply has been turned off to
avoid engine overheating.
5) After stopping the engine, remove
the garden hose adapter.
6) Replace the cap securely.
7) Repeat the flushing procedure for
the other engine.
