The Mercury Black Max 3-Blade Aluminum Propeller with part number 11324A45 offers a robust construction, reliable performance, and proven Mercury quality. With a diameter of 15.5 inches, a pitch of 18 inches, and a right-hand (RH) rotation, this propeller is ideal for powerful outboard engines as well as MerCruiser Z-drives in recreational and sport applications.

Made from patented Mercalloy® aluminum, the Black Max combines high strength with targeted material flexibility to absorb minor impacts. The result is a durable propeller with good acceleration, stable thrust, and smooth operation.

The propeller is supplied including the Flo‑Torq® II Hub Kit (835257Q1). The modular hub system ensures secure power transmission and protects the transmission and drivetrain during peak loads. It can be optionally upgraded to Flo‑Torq® SSR for even smoother and quieter shifting.
