ACME 422 4-Blade Wake/Ski Propeller 12.50" x 15.50" ACME422
Description ACME 422 4-Blade Wake/Ski Propeller 12.50" x 15.50"
ACME 422 4-Blade Wake/Ski Propeller – 12.50" x 15.50"
Designed specifically for wake and water ski boats, the ACME 422 propeller is a must-have for demanding enthusiasts. Its 4-blade design provides exceptional thrust and crisp acceleration even at low speeds—ideal for pulling a skier or wakeboarder out of the water quickly and smoothly.
With a diameter of 12.50" and a pitch of 15.50", this propeller offers an optimal balance between engine torque and cruising speed, ensuring consistent performance even under load. Its 0.105" cup depth improves grip in the water and reduces slippage during sharp accelerations.
Manufactured from Nibral alloy (nickel-bronze-aluminum) by ACME Marine, it is precision-machined on a CNC milling machine. Unlike cast propellers, this process ensures perfect balance, reduced vibration, and extended service life.
KEY FEATURES
- 4 blades for maximum thrust and instant start-up, even under load
- 0.105" pitch for better grip and less slippage during acceleration
- CNC machining for perfect balance and reduced vibration
- Optimized blade surface for improved efficiency and fuel economy
- Consistent speeds for perfectly repeatable skiing and wake conditions
- Manufactured by ACME Marine, the American leader in high-performance inboard propellers
MATERIAL: NIBRAL ALLOY
Nibral alloy (nickel-bronze-aluminum) is the gold standard material for high-performance propellers. It offers superior corrosion resistance compared to aluminum, stiffness comparable to stainless steel, and lower density for better dynamic performance. Ideal for intensive competition use.
