ENGINE
BREAK-IN
PROCEDURE
Careful treatment of a new engine
will result in more efficient perfor-
mance and longer life for the engine.
Polaris recommends the use of a
50:l gasloil premix in the fuel tank for
the
first tank full
of fuel to provide
additional lubrication during the
break-in period. A
50:l
ratio is one
pint
(.5
1) oil to six gallons (23
1)
gas.
After the break-in period the oil injec-
tion system provides the necessary
engine lubrication without the need
for pre-mixed fuel.
During the break-in period varying throttle speeds will contribute to good engine
break-in. Do not subject a new engine to heavy loads or full-throttle operation for
extended periods.
Do
not carry a passenger during the break-in period.
When starting the engine, be sure the watercraft is in water at least
2
feet (60 cm)
deep.
If
the engine is run in water less than two feet deep, sand, weeds and debris
may be sucked into the jet intake and damage the impeller or injure bystanders.
Ingestion of sand into the cooling system will cause the engine to overheat, result-
ing in possible severe engine damage.
1.
Launch the watercraft. Push the rear of the watercraft up and down several
times.
Check the throttle for free operation and start the engine. Let the
engine warm up for about a minute before departing.
2.
The lowest possible speed should be used for the first five minutes of
operation.
3. Gradually open the throttle to half speed.
4. Vary throttle speeds up to 314 speed during the break-in period.
Failure to follow the recommended break-in procedure can severely damage the
engine.
