ACME 497 4 Blade 13" x 17.75" Propeller

The ACME 497 4 Blade Propeller offers more surface area than comparable 3 blade propellers which means a more efficient transmission of power, higher fuel economy, and more consistent speeds. Thanks to ACME’s continued devotion to push the ski and wakeboard boat propeller industry to new heights inboard props are helping ski and wakeboard boats achieve performances never before seen.

Prior to 1999, ski and wakeboard boat propellers were cast from molds, a process that offered little precision and had severe limitations for the size and shape of the blades. The result was inefficient props with small blade surface area and poor balance which caused vibration in the boat drive train. However, all that changed when ACME introduced CNC machining to the inboard propeller industry. By precision machining its waterski and wakeboard boat propellers ACME is now able to hold tolerances and achieve accuracies never before seen in the inboard propeller industry.

What does that mean for you? The ACME 497 4 Blade Propeller will perform up to and surpass the standards you expect from the moment you pull it out of the box and put it on your boat.

Is this the right prop for your make and model of boat?
Upgrading a prop is rarely a case of going from a 3 blade to a 4 blade or 5 blade so don’t let the number of blades cloud your vision. The individual boat/engine combination, as well as how the boat is being used will determine which prop you need, and the best option may be a 3 blade, 4 blade or 5 blade.

Whether you want to upgrade the stock prop on your boat, or just need to replace a damaged prop, our Prop Finder guide will help you determine the perfect prop for your Year, Make, and Model ski and wakeboard boat.

Precision Machined Production Process
ACME’s industry leading CNC machining production process results in a prop that is accurate to one thousandth of an inch. That means silky smooth operation with no harshness or vibration.

This futuristic manufacturing process also opens the door for new prop designs that can’t be physically produced with cheaper casting production methods. That means more control over the shape, and therefore overall performance, of the prop than ever before.
