The MAX PROP® Boomerang propeller works completely automatically. It takes the pitch when the drive shaft is rotated to travel forward or backwards. The propeller feathers when engine is off, starting from the position to travel forward. This innovative propeller model, avoids the necessity of having to apply a shaft brake even for the boats equipped with an hydraulic gear.
The MAX PROP® Boomerang is equipped with a patented mechanism that allows the propeller blades to go back in feathering position automatically when the prop is still. Thanks to this innovative feature when the engine is stopped (whilst driving in forward), the blades are automatically and immediately pushed in to the feathering position.
The MAX PROP® Boomerang uses five blades to provide quiet operation and impressive thrust. Especially against heavy wind and seas, the fifth blade will maintain boat speed on a heavy vessel. Also, the fifth blade provides a smoother operation quieting down propeller noise on larger applications.
The MAX PROP® Boomerang is shipped fully assembled, making installation and pitch changes simple and fast. The pitch is variable up to 0,5°, providing the ability to fine tune up the loading of the engine. Moreover, pitch adjustment can be done in the water as the propeller does not need to be disassembled to change the pitch.
On the body of each propeller two threaded holes (housings) are obtained, marked with letters “R” and “L”; a screw/rod is inserted in each hole. The pitch of the propeller, for both forward and backwards motions, can be easily varied by changing how deeply each screw/rod penetrate the body.
The MAX PROP® Boomerang is also designed for larger moderate to heavy displacement vessels. Which can benefit from the extra thrust and quiet performance of a five blade propeller.
Very helpful also in applications where the propulsion system has very reduced space.
