The ACME 1939 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 1939 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.
So far, so good
I have a 2005 Moomba Mobius LSV. I broke the blade on the original prop - 13.7"x17.5" with this one. I was a little concerned with changing to this one with a lower pitch, but I have run the boat 3 or 4 time now with the new prop and I am very satisfied. I have a little more low end punch now, although I did lose a few mph off the top speed. Since we mostly wake surf, it is a good trade-off. Interestingly, when wake-surfing we run at about the same rpm on the new prop as we did on the original prop. I think the new prop has less slip when pushing all that weight at lower speeds.
Replaced my stock prop after hitting something and it becoming unbalanced. Wakemakers shipped it immediately and I was able to get it back on in no time. No notable performance gains as this is the stock prop that came with my enzo 233
Made a huge difference in performance!
We went from a 13.5" diameter Acme to a 14" with 15.5 pitch and wow, what a big difference from the old prop. Very happy with the advice I received from WakeMakers staff - very, very knowledgeable, and helpful in choosing the right prop. FYI we have a 2009 Nautique 210 SANS with 2,200 lbs of ballast. So glad we went with the 14"!
I ordered the 370lb tube sac for my mastercraft X30 to load more weight to the bow. It fits perfectly in the front bow, under the middle cushion so its not in the way of getting in/out of the drivers seat. It adds just enough weight to the bow, along with the tube sac in the ski locker, for the surf spot to be pushed back from the boat a couple feet. Im very happy I decided on the 370lb sac.
The new prop works great but is a bit expensive.
