TRANSPORTING YOUR OUTBOARD WHEN REMOVED
FROM BOAT
1
With the outboard still in the water, disconnect the fuel line from the outboard
and run engine until it stops, draining carburetor. Remove outboard from the
boat and hold upright until all cooling water is drained out. Lay the outboard
down horizontally on it's (tiller handle) side. Place a protective pad under the
outboard.

TRANSPORTING PORTABLE FUEL TANKS

Manual venting Type Fuel Tank
2
Close fuel tank air vent when transporting tank. This will prevent escape of fuel
or vapors from tank.
Auto-venting Type Fuel Tank
3
Disconnect the remote fuel line from tank. This will close the air vent and
prevent escape of fuel or vapors from tank.
4
Install tether cap (a) over the fuel line connector stem (b). This will protect the
connector stem from being accidently pushed-in, thus, allowing fuel or vapor
to escape.
WARNING
Avoid serious injury or death from a gasoline fire or explosion. Follow
portable fuel tank transporting instructions. Transport the fuel tank in a
well ventilated area away from open flame or sparks.

GASOLINE RECOMMENDATIONS

United States and Canada
Use a major brand of automotive unleaded gasoline with a minimum posted octane
rating of 87. Mid-grade automotive gasolines that contain fuel injector cleaner are
preferred for added internal engine cleanliness. Leaded gasoline is not
recommended.
International
Use a major brand of automotive unleaded gasoline with a minimum posted octane
rating of 90RON. Automotive gasolines that contain fuel injector cleaner are
preferred for added internal engine cleanliness. Leaded gasoline is acceptable in
areas where unleaded gasoline is not available.
Alcohol in Gasoline
We do not recommend the use of gasoline which contains alcohol because of the
possible adverse effect the alcohol may have on the fuel system. In general, if only
gasoline containing alcohol is available, it must not contain more than 10% ethanol
or 5% methanol, and the addition of a Water Separating Fuel Filter is
recommended.

If gasoline containing alcohol is used or if you suspect the presence of alcohol in
your gasoline, increase your inspection of the fuel system, visually checking for
fuel leaks or abnormalities.
Gasoline containing alcohol may cause the following problems to your outboard
and fuel system:
•
Corrosion of metal parts.
•
Deterioration of elastomers and plastic parts.
•
Wear and damage of internal engine parts.
•
Starting and operating difficulties.
•
Vapor lock or fuel starvation.
Some of these adverse effects are due to the tendency of gasoline containing
alcohol to absorb moisture from the air, resulting in a phase of water and alcohol
which separates from the gasoline in the fuel tank.
The adverse effects of alcohol are more severe with methanol and are worse with
increasing content of alcohol.

OIL RECOMMENDATION
Mercury or Quicksilver Premium TC–W3 2–cycle oil is recommended for your
engine. For added protection and lubrication, Mercury or Quicksilver Premium
Plus TC–W3 2–cycle oil is recommended. If Mercury or Quicksilver outboard oil
is not available, substitute another brand of 2–cycle outboard oil that is NMMA
Certified TC–W3. Severe engine damage may result from use of an inferior oil.

MIXING FUEL AND OIL

Use a 25:1 (4%) gasoline/oil mixture in the first tank of fuel.
After the break-in fuel mixture is used up, use a 100:1 (1%) gasoline/oil mixture
in engines used for pleasure applications. To provide additional protection for
commercially used products, a 50:1 (2%) gasoline/oil mixture is recommended.

FILLING FUEL TANK

WARNING
Avoid serious injury or death from a gasoline fire or explosion. Always
stop the engine and DO NOT smoke or allow open flames or sparks in the
area while filling fuel tanks.
Fill fuel tanks outdoors away from heat, sparks, and open flames.
Always stop engine before refilling tanks.
Do not completely fill the fuel tanks. Leave approximately 10% of the tank volume
unfilled. Fuel will expand in volume as its temperature rises and can leak under
pressure if the tank is completely filled.
Filling Fuel Tanks Permanently Installed
Slowly pour the correct amount of oil along with the gasoline as the tank is being
filled.
Filling Portable Fuel Tanks
Remove portable fuel tanks from boat to refill them.
Pour the full amount of oil along with approximately one gallon of gasoline into the
fuel tank. Mix thoroughly, then pour the remainder of gasoline into the tank.
Portable Fuel Tank Placement in the Boat
Place the fuel tank in the boat so that the tank vent will stay higher than the fuel
level in the tank under normal boat operating conditions.
