Carburetor Modification for

High Altitude Operation

TECHNICAL AND CONSUMER INFORMATION

When the carburetors have been

modif ied f or high altitude operation,

the air-f uel mixture will be too lean

f or low altitude use. Operation at

altitudes below 5,000 f eet (1,500

meters) with modif ied carburetors

may cause the engine to overheat

and result in serious engine damage.

For use at low altitudes, have an

authorized Honda Marine dealer

return the carburetors to original

f actory specif ications.

At high altitude, the standard

carburetor air-fuel mixture will be

too rich. Performance will decrease,

and fuel consumption will increase.

A very rich mixture will also foul the

spark plugs and cause hard starting.

High altitude performance can be

improved by specific modifications

to the carburetors. If you always

operate your outboard motor at

altitudes above 5,000 feet (1,500

meters), have an authorized Honda

marine dealer perform this carburetor

modification.

Even with carburetor modification,

engine horsepower will decrease

about 3.5% for each 1,000-foot (300-

meter) increase in altitude. The effect

of altitude on horsepower will be

greater than this if no carburetor

modification is made.
