Acme Automotive 2315 4-Blade Ski/Wake Propeller 15" x 12" LH 1-1/8" Bore

The Acme 2315 is a precision-engineered 4-blade inboard propeller specifically designed for waterski, wakeboard, and wake surf boats. With a 15-inch diameter and 12-inch pitch configuration, this left-hand rotation propeller delivers improved acceleration, superior pulling power, and enhanced fuel economy for heavily weighted inboard boats running 3,000 to 4,000 pounds of ballast.

Key Features:

• 15" diameter x 12" pitch with .105" cup for optimal performance
• 4-blade design with increased surface area for efficient power transmission
• Constructed from durable NiBrAl (Nickel-Bronze-Aluminum) alloy
• 1-1/8" (1.125") bore with 2.750" hub length for pin drive systems
• Left-hand rotation for inboard ski and wakeboard boats
• 100% CNC machined for precise diameter, pitch, and cup specifications
• Manufactured in the USA at QS-9000 certified facilities

Acme revolutionized the inboard propeller industry by introducing Computer Numerically Controlled (CNC) machining technology, replacing traditional hand-finished casting methods. This advanced manufacturing process ensures every propeller is produced to exacting tolerances, eliminating vibration and delivering box-to-boat performance consistency. The 2315's enhanced blade surface area provides more efficient power transfer than comparable propellers, resulting in crisp acceleration, consistent speed holding, and improved fuel efficiency—particularly beneficial when running heavy ballast loads for wake surfing and wakeboarding applications.
