Acme Automotive 515 3-Blade Ski/Wake Propeller 13x12 LH 1-1/8" Bore

The Acme 515 is a precision-engineered 3-blade propeller featuring a 13-inch diameter and 12-inch pitch, specifically designed for creating optimal wakes for water skiing, wakeboarding, and wakesurfing. This left-hand rotation propeller features a 0.080-inch cup and 1-1/8-inch bore, making it compatible with pin drive inboard systems.

Key Features:

• 100% CNC machined using computer numerically controlled milling machines for extremely accurate and consistent metal removal
• Constructed from cupped nibral (nickel-bronze-aluminum) for superior strength and corrosion resistance
• Cast in Acme's North American foundry and machined in QS-9000 certified manufacturing facilities
• Precision machining allows for larger blade surface area, improved efficiency, and perfect balance for smooth operation
• CNC process enables accurate production to exact diameter, pitch, and cup specifications with ability to dial-in incremental changes
• Box-to-boat ready—each propeller arrives ready for installation

The Acme 515 offers an excellent blend of low-end torque and top speed, making it a go-to performer for direct drive tournament ski boats. Common applications include Malibu Sportster, Response, Sunsetter series, and other popular water sports boats from manufacturers like Nautique, MasterCraft, Tige, MB Sports, and Centurion. This propeller produces similar RPM performance to a 13x13 hand-finished prop.

Acme revolutionized propeller manufacturing by implementing CNC machining, achieving tolerances and accuracies never before seen in the propeller industry. Backed by a 30-day warranty against manufacturing defects.
