Mercury 812954A10 Black Max Propeller — 8″ × 5″ RH Aluminum 4-Blade
The Mercury Black Max 812954A10 4-blade propeller delivers exceptional thrust and steering control for small outboards and kicker motors. Constructed from Mercury’s proprietary Mercalloy aluminum alloy, this 8″ × 5″ right-hand prop provides superior handling and durability. The added blade improves grip in tight turns and enhances low-speed maneuverability, while the built-in rubber hub bushing absorbs vibration for a smoother ride. The Phantom Black enamel finish helps prevent corrosion for reliable performance season after season.
Applications
For Mercury and Mariner 8–9.9HP FourStroke outboards (2005 and newer). Ideal for kicker motor applications or small craft requiring improved control. Always verify propeller size, hub design, and rotation in your owner’s or service manual before installation.
