Fuel Recommendations
CAUTION
Using a non-recommended fuel may cause
serious engine damage. Always use Polaris-
recommended fuels for your watercraft engine.
91 Octane
For the best performance from your MSX 110/150,
Polaris recommends the use of 91 octane fuel.
Performance will be less than optimal with lower
octane fuels.
89-90 Octane
Although 89-90 octane fuels are usable in your
watercraft, performance will be reduced. Choose a
higher octane fuel for better performance.
87-88 Octane
Use of 87-88 octane fuel is not recommended. If no
other fuel is available in an emergency situation, 87-88
octane fuel may be used temporarily. However, engine
damage can occur if engine speed exceeds 5000 RPM.
If 87-88 octane fuel must be used, keep engine speed
below 5000 RPM. Do not operate the watercraft at
wide open throttle. Return to using a higher octane fuel
as soon as possible. Never use a fuel lower than 87
octane.

Refueling
WARNING
Failure to follow proper refueling instructions can
result in fire or explosion, causing serious injury
or death. Always stop the engine and disconnect
the lanyard from the engine stop switch before
refueling.
When refueling, always use fresh, seasonal gasoline
that has been stored in a clean container. For the best
performance from gasoline, purchase only what is
needed for a month or less of operation.
1. Stop the engine and disconnect the lanyard from
the engine stop switch.
2. Carefully remove the fuel cap.
NOTE: Keep the watercraft horizontal while fueling.
3. Use a funnel or flexible spout to help avoid
spilling gasoline on the watercraft. Always wipe
up any spills immediately. Wash out the footwells
with water if fuel or oil spills in those areas.
