CONTINUING EVALUATIONS
The effects of gasoline with ETHANOL and METHA-
NOL are still being evaluated by the United States
Coast Guard, the National Marine Manufacturers As-
sociation (NMMA), Mercury Marine and other engine
and boat manufacturers.
We have recommended pump posting of alcohol
content of gasoline. Further we recommend using
gasoline known not to contain any METHANOL or
ETHANOL when possible.
TEST FOR ALCOHOL CONTENT IN GASOLINE
The following is an acceptable and widely used field
procedure for the detection of alcohol in gasoline.
Use any small transparent bottle or tube that can be
capped and is, or can be, provided with graduations
or a mark at about 1/3 full. A pencil mark on a piece of
adhesive tape may be used.
Procedure
1. Fill the container with water to the mark.
2. Add fuel almost to fill the container, leaving some
air space, then cap the container. The propor-
tions of fuel to water are not critical, but there
should be 2 to 3 times as much fuel as water.
3. Shake container vigorously and allow it to sit up-
right for 3 to 5 minutes. If the volume of water
appears to have increased, alcohol is present. If
you are not sure, there is no need for concern. If
the dividing line between water and fuel becomes
cloudy, use the middle of the cloudy band.
Crankcase Oil
To help obtain optimum engine performance and to
provide maximum protection, we strongly recom-
mend the use of Quicksilver 4-Cycle Marine Engine
Oil. If not available, a good grade, straight weight, de-
tergent automotive oil of correct viscosity, with an API
classification of SH, CF/CF-2 may be used.
The following chart is a guide to crankcase oil selec-
tion. Oil filter should always be changed with oil.
In those areas where recommended straight weight
oil is not available, a multi-viscosity 20W-40 (SH, CF/
CF-2) or, as a second but less preferable choice,
20W-50 (SH, CF/CF-2 ) may be used.

IMPORTANT: The use of non-detergent oils, mul-
ti-viscosity oils (other than 20W-40 or 20W-50),
low quality oils or oils which contain solid addi-
tives specifically are not recommended.
