Mercury Black Max Aluminum Propeller – 3-Blade, 15.3" × 15", Right-Hand Rotation incl. Flo‑Torq II Hub Kit (78116A45)

The Mercury Black Max 3-Blade Aluminum Propeller with part number 78116A45 offers proven Mercury quality, robust construction, and reliable performance for a wide range of boats. With a diameter of 15.3 inches, a pitch of 15 inches, and a right-hand (RH) rotation, this propeller is ideal for powerful outboards and MerCruiser Z-drives in general-purpose and recreational applications.

Made from patented Mercalloy® aluminum, the Black Max impresses with high strength while maintaining sufficient material flexibility to absorb minor impacts and stresses. This ensures long-lasting performance, good acceleration, and consistent thrust.

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