Whether you want to make your old ski boat feel like new or improve the performance of your new wakeboard boat, the ACME 4 Blade 17" x 19" Propeller will get the job done.

The ACME 3635 4 Blade 17" x 19" Propeller offers more surface area 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 3635 4 Blade 17" x 19" 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.

Prop Finder

Prop Finder

Finding the right prop for your boat is based on the individual boat/engine combination, as well as how the boat is being used. Whether you want to upgrade the stock prop, 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 boat.

Prop Left Rotation & Diameter

Rotation & Diameter

Rotation: Like bore, rotation is specific to the power train of the boat; if your boat needs a left-hand rotation propeller, you must use a left-hand rotation propeller.

Diameter: In general, a larger diameter means more surface area, which means better transmission of power from the engine to the water. Typically the diameter is limited by clearance around the prop, which is very important to check.

Prop Cup & Pitch

Cup & Pitch

Cup: is the curvature of the blade at its edge, primarily translates to the amount of load the prop will put on the motor.

Pitch: is the distance the prop would travel after making one full revolution. A lower numerical pitch number means higher engine RPMs relative to boat speed, which translates to better performance for slower speed activities.

Shaft Size 1 1/4

Shaft Size 1 1/4" Keyed

The bore of the propeller is specific to the prop shaft that is on your boat. Shaft size is not interchangeable, you must use the correct size prop for your boat’s shaft or the prop won’t fit.

Keyed: Measure the circumference of the prop shaft. Do the measurement in the middle of the prop shaft as it tapers as it gets closer to the propeller. Then use this formula to find the diameter. (diameter = circumference / 3.14)

Perfect for 2021 Nautique G23

The boat comes with 3433 17 x 17, but this prop is much better and reduces engine speed at cruise and increases top end speed by at least 5 mph.
