Figure 4-1
A Typical Sterndrive Gasoline System
Gasoline Containing Alcohol
Gasoline extended with alcohol, ethanol (ethyl alcohol) or methanol (methyl alcohol)
is not recommended for use in your engine.
If gasoline extended with alcohol is used, or if you are not certain alcohol is present,
the complete fuel system MUST BE inspected more often. If you observe any
indication of deterioration or leaks, DO NOT operate the engine, and have the
system repaired immediately.
Gasoline containing alcohol attracts and holds moisture and can cause the following
problems:
•
Hard starting, vapor lock and low speed or idle stalling.
•
Corrosion to the fuel system components.
•
Excessive wear and damage to internal engine parts.
•
Permeation of fuel through certain fuel lines and damage to some nonmetallic
materials.
Effects of alcohol are more severe with methanol and are worse as the alcohol
content increases.
