An automatic propeller shaft brake

Autolock is a propeller shaft brake that automatically stops the rotation of the shaft when the engine is turned off for sailing. When a hydraulic type gearbox is installed on your boat, sailing with the engine off may cause the propeller shaft to continue rotating. This rotation is transmitted to the gearbox, which is not properly lubricated and can be seriously damaged.

The advantages of Autolock

Autolock is designed to solve this problem and these are its advantages:

  • Locks the axle when sailing
  • Reduces gear wear
  • Reduces propeller resistance
  • Eliminates the noise of the gearbox turning
  • Constructed from rustproof marine materials

How Autolock works

Autolock is the only reliable axle brake available for boats with hydraulic gearboxes. It is automatically activated when the engine is turned off, being operated by the oil pressure of the gearbox itself.
