GENERAL INFORMATION 1-7
PROPELLERS
An outboard motor is designed to develop its rated power within
a specified engine speed range. The maximum rated power
delivered by the DF2.5 models are 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.

3 × 188 mm (7-3/8 in) × 135 mm (5-3/8 in)
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.
