Off -- Season Storage
Theoff-- s eason storage period is determined to be the time when 1. The watercraft will not be used for 30 or more
days, or, 2. The end of the normal riding season where the watercraft will be “winterized” for storage.
1. Remove the engine oil and replace with new.
S Used oil contains water, and un--burned fuel. When left inside the engine for extended periods of
time,internal engine corrosion can occur.
2. Flush the freshwater cooling circuit.
S Flushing the freshwater cooling circuit will remove salt, vegetation, and any other foreign material
trapped within the circuit.
3. Check the condition of the engine coolant.
S Using a coolant tester , commercially available, test the boil over and freeze temperature of the engine
coolant. A 50/50 mixture of distilled water to propolyne glycol should yield a freeze temperature of
approximately --26_F.
S A60/40 mixture (coolant --to -- distilled water) should be used where the water temperatures remain
cool throughout the year and where the air temperature drops below --26_F.
4. Top off the fuel tank with fresh fuel.
S Afull fuel tank will prevent the formation of moisture and mold inside the tank.
5. Add Polaris Premium Fuel Stabilizer , PN 2870652, to the fuel tank. Follow the mixing instruction outlined on
the bottle’s label.
S Fuel begins to break down and form varnish after 30 days. Adding stabilizer will prevent fuel from
breaking down.
6. Flush the engine compartment bilge with clean water.
S Cleaning the engine compartment bilge will prevent the growth of bacteria and mold.
7. Store the watercraft with the bow angled upwards at an angle of at least 10 degrees.
S Tilting the bow upwards will drain the water in the exhaust system as well as allowing any water in the
footwells to drain.
8. Always leave the seat loosely installed.
S Fresh air must be allowed to circulate inside of the engine compartment during storage periods.
9. Verify the battery is fully charged. Store the battery in a cool, dry place. Attach a battery tender to the battery,
or charge the battery once of month during the storage period.
10. Thoroughly clean the top deck and hull with mild detergent. Wipe dry and apply wax or furniture polish to hull.
