GENERAL INFORMATION
PROPELLERS
PROPELLERS
An outboard motor is designed to develop its rated power
within a specified engine speed range. The maximum rated
power delivered is shown below.
If the standard propeller fails to meet the above requirement,
use another pitch propeller to hold the engine speed within
the range specified above.
Propeller selection chart
Installing a propeller with pitch either too high or too low
will cause incorrect maximum engine speed, which may
result in severe damage to the motor.
