Propeller DOLPHIN 9-1/4 x 9: Honda, Yamaha 9.9-20 hp, type J

In selecting the right propeller, it's important to consider the engine manufacturer's maximum RPM. As a rule of thumb, 2-stroke engines typically have 4500-5500 RPM and 4-stroke engines 5000-6000 RPM. A 1-inch change in pitch can increase or decrease the engine's maximum RPM by about 200-300 RPM. Propeller size is indicated as follows: 10.3 x 12, where the last number 12 represents the pitch.
