Mazco O.S. Cleaver

The Mazco Offshore Cleaver propellers are of the highest quality on the market today. Bred from racing, they currently hold numerous world records and are the choice of most offshore champions.

These propellers are 1 piece casting of 15-5 P.H. stainless steel, the most desirable stainless for tensile strength. The hub I.D. and mating surfaces are bored and machined for exact tolerances. All of the propellers are heat treated, solution annealed and age hardened to 31-33 Rockwell to insure uniform strength.

The O.S. Cleavers are blueprinted for exact standards. They are formulated with a slight progressive pitch and straight rake to yield maximum performance. The blades are thinned for ultimate speed but yet thick enough for durability and are able to withstand the torque of the highest horsepower outboards. The propeller is then balanced to precise standards and is polished to a mirror finish to reduce drag. Each of our blueprinted cleaver propellers is assigned an identification number. This number is stamped on the propeller and added to our permanent records.

These propellers are available in 14 1/2″ and 15″ diameter with 26″, 28″, 30″, 32″ and 34″ pitches in both left hand and right hand rotation. Other pitches and diameters are available upon special orders.

So if you are looking for the utmost performance in a Race Boat, Offshore Cat, Deep “V” or Pleasure Boat, the Mazco Offshore Cleaver is the only way to fly.

Certain rotations and pitches are immediately available, if we don't have your preferred size in stock estimated delivery time is 8 weeks.
