Sierra MP28860 Replacement Kill Switch Lanyard – Yamaha Outboards
Keep your engine cut-off switch functional and your crew protected with the Sierra MP28860 replacement lanyard. Designed specifically for Yamaha outboard engines, this lanyard clips to the operator and connects to the emergency engine cut-off switch on the helm. If the operator moves away from the controls, the lanyard pulls free and immediately kills the ignition — a critical safety feature required on most recreational powerboats.
The MP28860 is built to seal out moisture, which helps prevent corrosion at the switch connection and makes reattachment easier after activation. Compatible with both conventional and magneto ignition systems.

Parts Desk Insights
This lanyard is the right pick when you have a Yamaha outboard and need to replace a lost or worn kill switch lanyard — a common maintenance item that's easy to overlook until it's missing. Always keep a spare on board.
