Propeller DOLPHIN 9-1/4 x 9: Tohatsu MFS9.9/15/20 4-stroke. M9.9/15 2-stroke

When choosing the right propeller, it's important to consider the maximum rpm specified by the engine manufacturer. As a rule of thumb, for 2-stroke engines, the range is 4500-5500 rpm, and for 4-stroke engines, it's 5000-6000 rpm. An increase or decrease of 1 inch in pitch can change the engine's maximum rpm by about 200-300 rpm. The size of the propeller is shown as 10.3 x 12, where the last number represents the pitch. Replace with product 51416-3BA-123. Features: 3-blade, 9.25 x 9, Hub 14 spline. Compatibility: Tohatsu M9.9 / M15 2-stroke, Tohatsu MFS9.9 / 15 / 20 4-stroke.
