A propeller that continues to rotate when a vessel is sailing can be major problem. It is most likely to affect yachts fitted with a hydraulic gearbox. To solve this problem we developed the Autolock.

As its name suggests Autolock is a shaft braking system for yachts fitted with hydraulic gearboxes. Its operation is totally automatic, springs apply the brake when the engine is turned off and the brake is automatically released by gearbox oil pressure as soon as the engine is started.

If you are looking for a reliable way to enable your feathering or folding propeller to do its job when you start sailing and want the added benefits of reduced gearbox wear, reduced prop drag and the elimination of the sounds of a prop shaft turning and intruding on your sailing, then the Autolock is your solution
