ACME 2739 22.00" LH 23.00" 4 Blade NiBral Cruiser Propeller
The ACME 2739 4 Blade NiBral Propeller offers more surface area than comparable 4-Blade propellers which means more efficient power, higher fuel economy, and more consistent speeds. Thanks to ACME’s continued devotion to pushing the boat propeller industry to new heights, the ACME Cruiser inboard props are helping boats achieve performances never seen.
All ACME inboard Cruiser Propellers are cast in their own North American foundry and 100% CNC machined in one of their two QS-9000 manufacturing facilities.
Diameter: 22.00"

Blades: 4
Rotation: Left
DAR: 0.75
ACME Cupping estimates for engine load based on a gear ratio of 1.5:1 @ 2800 RPM.
0.000 = Same as design pitch
0.045 = adds 1” to design pitch
0.075 = adds 1-1/2” to design pitch
0.105 = adds 2” to design pitch
0.135 = adds 2-1/4” to design pitch
Example: If a blade design pitch is 24 + (.075 Cup) effective pitch is 25
NOTE: If ratios and max RPM’s change higher or lower, it will change data above slightly +/-.
