MAINTENANCE AND LUBRICATION
Cooling System Flushing
The watercraft uses water for propulsion and for
cooling. Flushing the cooling system with fresh water
(never anti-freeze) will neutralize the corroding effects
of salt water or water with impurities like silt, sand,
alkali and other particles. Flushing will also clean out
other residue left in the water passages of the
watercraft cooling system.
Flush the water passages every day the watercraft is
used, any time the craft has been beached and before
storing the craft for an extended time.
Polaris recommends the use of Flush Kit PN 2873623
when flushing the cooling system.
1. Attach a garden hose to the female coupler/hose
attachment.
2. Snap the male and female coupler together.
3. Start the watercraft engine and immediately turn
on the water faucet.
4. Rev the engine intermittently for one minute to
completely flush the cooling system.
5. Turn off the water faucet.
6. When all water has exited the cooling system, turn
off the engine. NOTE: This step should not take
longer than 10 seconds.
7. Press the button on the female coupler/hose
attachment and separate from male coupler.
CAUTION
Failure to follow the recommended flushing
procedure or flushing the engine while it’s hot could
result in serious engine damage. Always follow the
recommended flushing procedures. Always allow
the engine to cool sufficiently before flushing.
Always flush the cooling system any time the
watercraft has been beached.
