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 DF200/225/250 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.

NOTE:
In case of twin installation, always use on both engines, the
same size right-hand rotation and counter-rotation propellers.

throttle speed range
DF200 5 000 – 6 000 r/min
DF225 5 000 – 6 000 r/min
DF250 5 500 – 6 100 r/min
Right-hand rotation models
Blade × Diam. (in.) × Pitch (in.)
3 × 16 × 17
3 × 16 × 18 and 1/2
3 × 16 × 20
3 × 16 × 21 and 1/2
3 × 16 × 23
3 × 16 × 24 and 1/2
Counter rotation models
Blade × Diam. (in.) × Pitch (in.)
3 × 16 × 17
3 × 16 × 18 and 1/2
3 × 16 × 20
3 × 16 × 21 and 1/2
3 × 16 × 23
3 × 16 × 24 and 1/2
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.
