The ACME 1578 4 Blade Propeller is designed specifically for waterski and wakeboard boats to offer improved acceleration, speed holding pulling power and fuel economy.


The ACME 1578 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 1578 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.

    Best upgrade yet!

    2003 Super Air Nautique, nearly 3000# of ballast and I jumps out of water like it's not loaded at all. Incredible. Don't really care about top end. Hold speed through turns and for surfing much better than stock.

    Excellent purchase. Just what our 2001 Super Air Nautique needed.

    We ride in the High Lakes of the Oregon Cascades. Upgrading to the ACME 1578 prop with the lower pitch makes the boat pop riders right up. It also made the wake surfing speed more consistent and powerful. We ride at 4500+ feet elevation with about 1500 pounds of ballast. We can feel the increase in pulling power with every start. Worth every penny and thanks for the sale price.
