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.

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.

MAINTENANCE AND LUBRICATION

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.
