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.

  • Ideal for local and long range cruiser
  • Available from 11″ to 48″ for shafts 3/4″ to 3-1/2″ or metric equivalent also available for Saildrives

Efficient 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

Very 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.
