ACME 1634 20.00 RH 20.00" 4 Blade NiBral Cruiser Propeller

The ACME 1634 4-Blade 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.

Pitch: 20.00"

Cup: .045

Hub Length: 3.750"

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 +/-.
