Boat Maintenance Section 6
Fuel System
You must take appropriate steps to protect your boat’s
fuel system and engine during extended 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 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 your engine during
storage:
• 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 your engine at idle for at least ten minutes to
pump stabilized fuel through the engine’s fuel sys-
tem
• 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.
