Boat manufacturers should follow the gasoline storage mixture sec-
tion for testing prior to shipment. Fuel stabilizer can be purchased lo-
cally at most marine supply stores.
Limited Use
If the vessels fuel within the tank(s) will not be consumed within a 30-
day period from the time of filling, a gasoline fuel stabilizer must be
added as per the manufacturer’s instructions. This will help prevent
the fuel from breaking down and causing reduced engine perfor-
mance fuel system clogging or damage from uncontrolled combus-
tion.
Storage
If the boat is being placed into storage, a gasoline fuel stabilizer must
be added to the tank(s) as per the manufacturers instructions. The
amount of stabilizer required is determined by the quantity of fuel
and the length of time it will be placed in storage. The maximum pe-
riod that fuel can be stabilized is six months due to limitations of the
stabilizers and fuels.
WARNING!
Any fuel leakage should be corrected immediately to
prevent possible fire and/or explosion.
NOTICE!
Do not run engine out of fuel or run the electric fuel
pumps dry more than 20 seconds. Running the elec-
tric fuel pumps dry will cause fuel pump damage.
Step 1. Prepare a storage mixture
In addition to stabilization of the fuel, it is highly desirable to have the
valves and cylinders coated with a light film of oil previously accom-
plished through fogging. Today’s fuel injection manifolds are de-
signed with a complex air channel design that will not allow the
traditional fogging oils to be injected past the throttle plate while run-
ning. The oil will get stuck in the plenum and never reach the cylin-
ders. Together with the stabilizer, two-cycle motor oil can be added
to a fuel mixture for stabilization purposes.
• Using an outboard motor six-gallon fuel tank, add two-cycle
motor oil at a ratio of 50:1 (one pint to 6 gallons) and stabi-
lizer at one ounce per gallon (unless stated otherwise on the
manufacturers label). Mix well.
• Disconnect boat fuel line at engine fuel pump. Attach the
storage mixture fuel tank.
• Connect a suitable engine flush device if the boat is not in
the water.
• Run the engine on the storage mixture for approximately 5
minutes at 1500 RPM. This will ensure that all fuel system
and internal engine components are thoroughly protected.
Do not operate the engine above 1500 RPM as the water
pump demand may exceed the supply, damaging the pump.
• Reduce the engine speed to idle and stop the engine.
• Reconnect the fuel fitting and check for fuel leaks.
