Sierra MP28880 Replacement Kill Switch Lanyard – Johnson/Evinrude Outboards
Replace a lost or worn kill switch lanyard and restore your engine cut-off system to full working order. The Sierra MP28880 is designed specifically for Johnson and Evinrude outboard engines, clipping to the operator and connecting to the emergency cut-off switch at the helm. If the operator is separated from the controls, the lanyard pulls free and immediately kills the ignition — a critical safety function on any powered watercraft.
The moisture-sealed connection resists corrosion and makes reattachment straightforward after activation. Compatible with both conventional and magneto ignition systems.

Parts Desk Insights
This is the right lanyard when you have a Johnson or Evinrude outboard and need to replace the kill switch lanyard — one of the most commonly lost safety items on a boat. Always keep a spare on board; without it, the cut-off switch is non-functional. If your engine is Yamaha-powered, the Sierra MP28860 Replacement Lanyard for Yamaha is the correct fit instead. If you need a complete kill switch and lanyard assembly rather than just the lanyard, the Sea-Dog 10-Key Universal Kill Switch with Lanyard, Sea-Dog 7-Key Universal Kill Switch with Lanyard, or the Sea-Dog Dual-Circuit Safety Kill Switch are full-assembly options that fit a wide range of outboard brands.
