Propeller SOLAS: 11-3/8 x 15: Evinrude, Johnson, Suzuki 40-50 hp 4-stroke

When selecting the right propeller, it's important to take into account the maximum RPM specified by the engine manufacturer. A rule of thumb is for 2-stroke engines, the range is 4500-5500 RPM, and for 4-stroke engines, it's 5000-6000 RPM. A one-inch change in pitch can raise or lower the engine's max RPM by about 200-300 RPM. Propeller size is indicated as follows: 10.3 x 12, where the last number, 12, represents pitch.
