The ACME 2247 4-Blade Propeller offers more surface area than comparable 4-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 2247 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.
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.
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.

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.

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)
Never again worry if the propeller you buy is going to deliver the performance you need. Think of our Performance Protection Plan as a guarantee that the propeller you purchased will provide the desired performance. If it does not do what you want, simply exchange it for a different model.
My Old prop was bent slightly causing major steering vibrations especially under full ballast. I switched to this prop and it drives smooth as butter. That’s me in the video… and Also, one novice surfer in my group dropped the rope and found the pocket for the first time on the first session with this prop! Coincidence? I think not… the wave is better than ever!
It lowered my RPM's and quieted my engine. Picked up more low end torque. Wish I would of bought it sooner!
I have a 2005 wakesetter 23LSV and I upgraded from an Acme 537 to the 2247 and I could not be happier! First off, I only lost about 3mph on my top end but what I’ve gained is incredible! I can load my boat with all 3000 lbs of ballast, drop the manual wedge, and still plain out! The boat runs so much smoother while we surf, and hold the perfect pass much more accurately! I love that it doesn’t take near as much to get up to wakeboard speed which is saving fuel for sure! Perfect prop for my boat, and many others! Fantastic support from the crew at Wakemakers!!
Just installed on my 2007 Malibu 23LSV (indmar 340) and this prop way exceeded my expectations! With 4 people (800 lbs), approx 3,000 lbs ballast and 11.4 mph the rpms were reading around 2,900. The engine sounds quieter, runs smoother and there is zero issues with the hole shot, or maintaining speed. What impressed me most was that I still reached 43mph on the top end with 5 people in the boat and rpm's stayed just under 5,000. Couldn't be happier with the overall performance!
products and shipment were great
