Boat Maintenance
Fuel System
You must take appropriate steps to protect your boat’s
fuel system and outboard engine during periods of
non-use. Situations where fuel isn’t being consumed
and exposure to extreme changes in temperature will
cause condensation to accumulate in your fuel sys-
tem. This moisture can compromise your fuel, your
fuel system, and your outboard engine.
Use a high-quality fuel stabilizer formulated for gaso-
line containing ethanol when you perform these steps.
Review the storage information contained in your
engine operator’s manual.
Follow these suggestions to minimize the possibility of
damage to your fuel system and engines during stor-
age:
• If possible, use fuel that does not contain ethanol
on a regular basis, or just before storing your boat
• Store your boat with the fuel tank
full
to avoid
exposing the fuel to moisture in the atmosphere
• Refer to
Fueling Procedures
in Section 3 of this
manual for fueling information
• Add a high-quality fuel stabilizer to the fuel follow-
ing the additive manufacturer’s recommendations
• Run the outboard engine at idle for at least ten
minutes to pump stabilized fuel through the
engine’s fuel system
• If possible, store your boat where it will not be
exposed to extreme changes in temperature
Refer to
Blended Fuels
in Section 3 of this manual for
more information about moisture and gasoline.
