A large majority of modern production sailboats are equipped with a "SailDrive" leg instead of a propeller shaft. These "SailDrives" require a different type of propeller for two reasons:
The Max-Prop "Easy Antishock" for SailDrive is designed to fit on any drive leg on the market today including Volvo, Yanmar, Bukh, and Twin Disc. This propeller system greatly reduces the shock load upon engaging the transmission which remains much lower than all SailDrive manufacturers maximum load requirements.
The installation of a Max-Prop "Easy Antishock" is identical to a fixed blade propeller.
A dampening device is installed internally on all Max-Prop "Easy Antishock" propellers. This dampening device is essential for preventing shock loads while engaging the drive in forward or reverse.
If your engine achieves either too much or to 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 the propeller does not need to be disassembled to change the pitch.
Arrives pre-assembled. Unique design allows for simple bolt onto the shaft installation.
