OPERATION
Engine Break-in Procedure
CAUTION
If the engine is operated while the watercraft is in
very shallow water, sand, weeds and debris may
be sucked into the jet intake and could cause
damage to the impeller or injury to bystanders.
Ingesting sand into the cooling system will cause
the engine to overheat, which could lead to
engine damage.
Whenever starting the engine, always be sure the
watercraft is in water at least two feet (60 cm)
deep.
Perform the following procedures carefully.
1. Make sure the drain plugs are installed securely
and launch the watercraft.
2. Push the rear of the watercraft up and down several
times in the water.
3. Check the throttle for free operation.
4. Remove the seat and ventilate the engine
compartment.
5. Secure the seat, board the craft and start the
engine. Allow it to warm up for about a minute
before departing.
6. Operate the watercraft at the lowest possible speed
for the first five minutes of operation.
7. Gradually open the throttle to half speed (half
throttle).
8. Vary throttle speeds frequently, up to 3/4 speed,
during the 12-hour break-in period. Do not
operate at full throttle for extended periods during
the break-in period.
9. Change the oil and oil filter after 12 hours of
operation. See page 77.
10. Have your Polaris dealer inspect and adjust the
engine valve lash after 12 hours of operation.
