Product Details

The Acme 3311 is a CNC-machined 4-blade inboard propeller designed for wake and ski boats requiring increased ballast performance. With an 18.00" diameter and 14.00" pitch, this left-hand rotation prop delivers powerful thrust, smooth cruising speeds, and improved fuel efficiency compared to traditional cast propellers.

Key Features:

  • Diameter: 18.00"
  • Pitch: 14.00"
  • Blades: 4
  • Rotation: Left-Hand (LH)
  • Bore: 1.25" (1-1/4")
  • Cup: .120"
  • Hub Length: 3.750"
  • Material: Nibral (Nickel-Bronze-Aluminum alloy)
  • 100% CNC machined for precise balance and consistency
  • Cast in a North American foundry and finish-machined in QS-9000 certified facilities

ACME's CNC machining process — introduced to the inboard propeller industry — eliminates the imprecision of hand-finished props, resulting in superior blade balance, reduced drivetrain vibration, and consistent on-water performance right out of the box. The 4-blade design provides greater blade surface area for more efficient power transmission, higher fuel economy, and more consistent speeds — especially on heavier, ballasted wake boats.

I got the wrong part and the phone number doesn't work

Great!

Ordered it, came it good time, was the right one, put in my car, now it's working like a beauty. Couldn't ask for anything different

I am satisfied with the delivery.

Thanks

THMotorsports had some tires in a size that I was having a hard time finding elsewhere. The price was fair, the shipping super fast, and the tires were exactly as described. Thanks THMotorsports!
