Acme Automotive 2773 15x13 4-Blade Left Hand Inboard Wake/Ski Propeller 1-1/8" Bore Nibral

The Acme 2773 is a CNC-machined 4-blade Nibral inboard propeller engineered specifically for waterski, wakeboard, and wake-surf boats. With a 15" diameter and 13" pitch, this left-hand rotation prop delivers a well-balanced combination of acceleration, speed-holding pulling power, and fuel economy.

Key Features:

• 100% CNC Machined — Computer Numerically Controlled milling ensures exceptional accuracy and consistency, eliminating the variables that cause vibration and poor performance in cast propellers
• Nibral Construction — Nickel-bronze-aluminum alloy provides superior strength, corrosion resistance, and durability
• 4-Blade Design — Increased blade surface area compared to 3-blade props delivers more efficient power transmission, cleaner wakes, and more consistent speeds
• Left-Hand Rotation — Correct rotation for standard inboard drivetrain configurations on ski and wakeboard boats
• Made in the USA — Cast in a North American foundry and CNC machined in QS-9000 certified manufacturing facilities
• Box-to-Boat Ready — Each propeller ships ready to install with no additional finishing required
