Operation
PRE-STARTING
IMPORTANT: 2-cycle engines require that oil be mixed with gasoline (refer to Fuel section below for proper
mixture).
CAUTION:
Make sure all hardware is tight, all safety devices are in place and operating, all adjustments are
made correctly, that Stop Switch on models equipped with them, stops motor and that Throttle
Lever moves freely.

Fuel

IMPORTANT: Failure to mix oil with gasoline will result in seizure and severe damage to motor. DO NOT use
gasohol or gasoline containing alcohol because alcohol will attack and cause internal parts to deteriorate. Use
unleaded gasoline for best performance.
NOTE: To prevent foreign particles from entering tank while filling: wipe dust, dirt and debris from around cap
before removing it.
WARNING:
Gasoline is highly flammable and must be handled with care. Allow motor to cool several
minutes before removing fuel tank cap. Never fill tank when motor is running or hot from
operation. Do not allow open flame, matches, or smoking in area. DO NOT overfill. Wipe up any
spills and allow vapors to dissipate. Use approved (Red) gasoline container.
Tanaka 2-cycle oil has been formulated to insure maximum motor performance and increased motor life.
Premix Tanaka oil per instructions on container. If Tanaka oil is not available, select a quality 2-cycle approved
oil and use unleaded gasoline.
If oil manufacturer does not recommend a specific mixing ratio, mix at a 1 to 50 ratio (2.6 ounces oil per
gallon of unleaded gasoline). Always use branded 89 octane unleaded gasoline.
NOTE: After fuel mixture has been left standing for a prolonged
period of time it will begin to separate, therefore thoroughly shake
mixture before using.

Motor must be mounted in center of boat transom. Recommended
transom height is 20". Clamp to transom with clamp stud handles
turned hand tight. Secure unit to transom using a safety
