Operating at High Elevations
IMPORTANT: To prevent serious damage to the engine caused by a lean fuel
mixture, do not operate your outboard (if the jets were changed for high
elevation) at a lower elevation unless the jets are changed again to correspond
to the new elevation.
Operating your outboard at an elevation higher than 750 m (2500 ft) above sea
level may require a carburetor jet change and/or different pitch propeller.
Consult your dealer. This will reduce the normal performance loss experienced
as a result of reduced oxygen in the air causing an overly rich fuel mixture.

ENGINE BREAK-IN FUEL MIXTURE
Use a 25:1 gasoline/oil mixture in the first tank of fuel.
The use of poor quality fuel will shorten the life of a motor and cause trouble,
including starting failure. It is recommended to use a high quality gasoline and
genuine or recommended engine oil. (Refer to Fuel and Oil section.)
