OPERATION
Principles of Operation
The engine is directly coupled to a driveshaft. When
running, the driveshaft rotates the impeller. The
impeller is positioned so that water is drawn up from
beneath the watercraft. The water travels through the
impeller and is accelerated, producing thrust to move
the watercraft forward. Pulling or squeezing the
throttle lever increases engine speed (watercraft speed).
Turning the handlebar pivots the jet pump nozzle
(water outlet) which controls the watercraft’s direction.
The throttle must be applied in order to turn the
watercraft.
Engine Break-in Procedure
The break-in period for your new Polaris watercraft is
defined as the time it takes to use the first full tank of
gasoline. No single action on your part is as important
as following the procedures for a proper break-in.
Careful treatment of a new engine will result in more
efficient performance and longer life for the engine.
Perform the following procedures carefully.
CAUTION
Excessive heat build-up during the first three
hours of operation will damage close-fitted engine
parts. Do not operate at full throttle or high speeds
for extended periods during the break-in period.
Do not carry passengers during the break-in
period.
Use of any oils other than those recommended by
Polaris may cause serious engine damage. We
recommend the use of Polaris synthetic 2-cycle
oils for your Polaris watercraft.
