Automatic Feathering Propeller

Four Blade Max-Prop Fast

    Maxprop 4 Blade Easy
  • Completely redesigned hub and blades
  • Very rugged construction
  • Super smooth body (no fasteners are visible)
  • Exceptional forward power
  • Exceptional reverse power
  • Externally adjustable pitch (no need for a haul out)
  • 4 blade design provides the smoothest possible run under power
  • One piece installation (can be done easily by a diver, no need for a haul out)

The Max-Prop Fast is a leap forward from the VP Max-Prop design. The ease of installation and simple pitch adjustment make this model a great choice for a wide range of boats. The four blade design provides smooth and efficient power. It also offers better punch when powering into heavy wind and seas.

The VP Fast ships fully assembled, making installation similar to a fixed propeller, basically slide it onto the shaft, nut it in place and the propeller is ready to go.

As with all Max-Prop’s the Fast pitch is adjustable. With the FastI the pitch is adjustable in 1 degree increments, providing the ability to fine tune the loading of the engine. Pitch adjustment can be done in the water as it does not require any special tools or disassembly to change the pitch.


  • maxprop 4-blade fastEfficient power:

    In forward the Max-Prop will offer 96% of the efficiency of a fixed blade propeller of the same diameter and pitch. The 4% loss in power can usually be eliminated by precisely matching the pitch of the Max-Prop to fit the boat engine combination. Four blade model will maintain boat speed about 12% better than a three blade when powering into heavy wind and seas.
  • Outstanding reverse:

    the Max-Prop provides 80% more power than a comparable fixed blade propeller. The Max-Prop utilizes the same leading edge in forward as it does in reverse giving the propeller the same thrust in both directions dramatically improving control and power in reverse.
  • Smooth operation:

    A four blade propeller will smoothest possible run under power, quieting down your drivetrain.
  • 4 blade fast assembly maxpropVery Low drag:

    Just like other Max-Prop propellers, the Fast feathers to a low drag position while sailing. Under sail the Max-Prop will increase sailing speed by about 15%, the largest difference being noticed when sailing in light air. When sailing with a fixed propeller the vessel has to overcome the fixed blade drag, installing a Max-Prop maximizes sailing performance.
  • Very easy installation:

    The installation of the Max-Prop Fast is very simple. The propeller is delivered assembled. Just slip the hub on the shaft, thread and tighten the nut, thread the two, lock screws for the nut, install the zinc anode (3 screws), and it is done!
  • Max-Prop PYI Four-Blade FastAdjustable pitch:

    If your engine achieves either too much or too little RPM at max throttle, adjust the pitch to a higher or lower setting to attain the correct RPM. Pitch adjustment can be done in the water as no disassembly or special tools are needed to change the pitch.

Available from 14” to 40” For shafts 1” to 3” or metric equivalent Also available for a SailDrive
