The original Max-Prop was designed in the early 70’s for the high tech race boat market. Since proving itself in the racing arena, the Classic Max-Prop has earned its way into the mainstream market as the leader in low drag propellers. Today you will find the Classic Max-Prop on a wide range of vessels from modest 25 foot daysailer to 150 foot classic schooner.

With the increased popularity of the cruising vessel, Max-Prop introduced the three blade classic model in the early 80's. This propeller will enhance a vessel's performance both under power with less vibration, better power in load conditions and under sail with reduced drag.

Features:

  • Maxprop 3 Blade PowerEfficient 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. The three blade has a major advantage when going against heavy winds and seas, it will maintain the boat speed up to 30% better than the two blade.
  • 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.
  • Reduces Vibrations:

    A three blade propeller will run much smoother than a two blade and reduce vibrations as it is balanced around three points as opposed to two
  • Unequaled Reliability:

    With over 35,000 Classic Max-Props in the water, the Classic Max-Prop has become a legend in the sailing community for its durability
  • 3-blade classic side viewVery Low Drag:

    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.
  • Internal Adjustable Pitch:

    All Max-Props have adjustable pitch settings. The Classic is adjustable in 2 degree increments. This can be done in minutes by disassembling it and reassembling it to the new configuration.
