IMPORTANT: Only use fuel additives approved by
Bombardier
for your outboard. Use of other fuel ad-
ditives can result in poor performance or engine
damage.

fuel conditioner will help
prevent gum and varnish deposits from forming in
fuel system components and will remove moisture
from the fuel system. It can be used continuously
and should be used during any period when your
engine is not being operated on a regular basis. Its
use will reduce spark plug fouling, fuel system icing,
and fuel system component deterioration.
FUEL/OIL RATIO
New Engine
During break-in, you must use a 50:1 (2% oil) fuel/
oil ratio in your fuel tank in addition to the operation
of the oil injection system. Refer to Break-In (10
hours).
Normal Operation
Your motor is equipped with an oil injection system
to automatically mix oil with fuel.
IMPORTANT: Operating this motor without the oil
injection system requires modification that must be
performed by your DEALER.
High Performance
During high performance operation you must use a
50:1 (2% oil) fuel/oil ratio in your fuel tank in addi-
tion to the operation of the oil injection system.
MIXING FUEL AND OIL
To provide your engine with extra oil, use the follow-
ing chart and these guidelines to mix oil with the en-
gine’s fuel. Otherwise, keeping oil in the oil tank is
all you need to do to satisfy the engine’s oiling re-
quirements.
Portable Tank
Above and below 32° F (0° C), add one gallon of fu-
el. Pour in required amount of oil. Add remaining fu-
el. Install filler cap and tip tank gently to distribute
oil.
Permanently Installed Tank
Above 32° F (0° C), pour oil slowly with the fuel as
tank is filled. Below 32° F (0° C), add one gallon of
fuel to a separate container. Pour in required
amount of oil. Install filler cap and tip container gen-
tly to distribute oil. Slowly pour oil/fuel mixture into
tank with fuel as tank is filled.
