General information
NOTE
If the recommended engine oil grades are not available, select an alternative from the following
chart according to the average temperatures in your area.
CAUTION
All 4-stroke engines are shipped from the factory without engine oil.
Propeller selection
The performance of your outboard motor will be critically affected by your choice of propeller, as
an incorrect choice could adversely affect performance and could also seriously damage the
motor. Engine speed depends on the propeller size and boat load. If engine speed is too high or
too low for good engine performance, this will have an adverse effect on the engine.
For a greater operating load, a smaller-pitch propeller is more suitable as it enables the correct
engine speed to be maintained. Conversely, a larger-pitch propeller is more suitable for a smaller
operation load.
NOTE
If the recommended engine oil grades are not available, select an alternative temperatures in your area.
1. Propeller diameter in inches
2. Propeller pitch in inches
3. Type of propeller ( propeller mark )
NOTE
Select a propeller which will allow the engine to reach the middle or upper half of the operation
rage at full throttle with the maximum boat load. If operation conditions such as light boat loads
then allow the engine r/min to rise above the maximum recommended range, reduce the throttle
setting to maintain the engine in the proper operation range.
