1-6 GENERAL INFORMATION
PROPELLERS
An outboard motor is designed to develop its rated power within
a specified engine speed range. The maximum rated power
delivered by the DF25 / 30 models are shown below.
Blade × Diam. (in.) × Pitch (in.)
3
× 10 - ¼ × 9 (P901)
3
× 10 - ¼ × 10 (P1001)
3
× 10 - ¼ × 11 (P1101)
3
× 10 - ¼ × 12 (P1201)
3
× 10 - ¼ × 13 (P1301, PS1301)
3
× 10 - ¼ × 14 (P1401)
3
× 10 - ¼ × 15 (P1501)
If the standard propeller fails to meet the above requirement,
use another pitch propeller to hold the engine speed within
the range specified above.

throttle speed range
DF25 5000 – 5600 r/min
DF30 5500 – 6100 r/min
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.
