A Security System You Can Trust.

The Mercury Theft Deterrent System (TDS) improves boat and engine security and provides owner ease of mind by allowing you to immobilize the engine if someone starts the engine without inserting the fob.

In the event that the fob is missing or not the correct one, Mercury TDS allows you to start the engine but limits RPM and performance while still allowing slow speed operation. Until the system is fully engaged with the fob fully inserted in the docking station, the engine will only operate at this reduced power range and performance will be restricted. Once TDS is deactivated with the fob, the engine will perform at normal operating ranges.
