Acme Automotive 541 3-Blade Inboard Ski Boat Propeller 13" x 12" Left Hand

The Acme 541 is a precision-machined 3-blade propeller designed for direct drive inboard ski boats, wakeboard boats, and surf boats. This propeller features a 13" diameter and 12" pitch, with .080" cup and 1" bore, optimized for left-hand rotation. The Acme 541 is ideal for direct drive boats that are weighted for surfing or wakeboarding but still need decent top end to pull skiers or cruise across the lake.

Key Features:

• CNC-machined construction provides unprecedented precision and accuracy, eliminating the inefficiencies of traditional cast propellers
• Cast from nickel-bronze-aluminum alloy (NiBrAl) for superior strength and corrosion resistance
• Larger blade surface area delivers improved efficiency and perfectly balanced operation
• Hub length: 2.750" for proper shaft fitment
• Delivers holeshot and top-end performance comparable to many 4-blade propellers
• 100% Made in the U.S.A. in QS-9000 certified manufacturing facilities

This propeller is a common direct drive 1:1 transmission replacement prop for general applications in older ski boats with 1" shafts. The precision CNC manufacturing process ensures smooth, vibration-free operation and consistent performance on the water.
