Mercury 300 HP Outboard CNC 18 Rake Cleaver 8M0189130 RH 15.25 x 29

The Mercury Racing 300HP 5-blade 18 Rake Mercury Racing CNC Outboard Cleaver propellers are recommended for use with the Mercury Racing 300R outboard fitted with the surface-piercing Sport Master gearcase. The precision-machined props are designed to maximize boat performance and handling in a variety of 300R Sport Master applications. Mercury Racing’s proprietary 5-axis CNC production process yields the most consistent, durable, and advanced propellers we have ever produced. Outboard Cleaver propellers are available with pitch ranges of 26 to 40 inch, 14.63 to 15.25 inch diameter, and 15 or 18 degree rake.

The surface-piercing 5-Blade CNC Cleaver propeller is designed to maximize top-end speed on performance hulls powered by Mercury Racing outboards equipped with the Sport Master or R-Drive Sport gear case. The precision-machined five-blade propeller is produced on the same state-of-the-art five axis CNC machines used to mill Mercury Racing’s legendary five- and six-blade sterndrive cleaver propellers. Every CNC propeller is delivered in a Mercury Racing Propeller Case.
