The Sea-Dog 10-Key Universal Kill Switch with Lanyard is a marine-grade emergency cut-off that stops the engine the moment the operator leaves the helm. The included 50-inch lanyard clips to your life jacket or wrist and pulls free if you fall overboard, tripping the switch and cutting power before the boat can run unmanned. The 10-key connector fits the kill-switch receptacles found on the most common outboard brands, making this a practical replacement or upgrade for a wide range of boats and personal watercraft.
Key Features
- 10-key lanyard connector fits Johnson, Evinrude, Mercury, Yamaha, Honda, Tohatsu, Suzuki, Kawasaki, OMC and Nissan kill switches
- 50-inch lanyard — long enough for comfortable movement at the helm
- Instantly cuts battery power when the lanyard is detached
- Injection-moulded nylon and Delrin construction
- Weatherproof and corrosion-resistant
- Weight: 82 g / 2.9 oz
Intended Use
Designed for outboard-powered boats and personal watercraft where the engine uses a 10-key kill-switch receptacle. Attach the lanyard to your life jacket or wrist before getting underway so the engine stops automatically if you are separated from the controls.
Fitment Notice
This switch uses a 10-key lanyard connector. Confirm that your engine’s kill-switch receptacle accepts a 10-key plug before ordering. If your engine uses a different connector style or requires a panel-mounted switch, see the Sea-Dog Universal Kill Switch — Dual-Circuit Ignition Cut-Off or the Sea-Dog 4204871 Safety Ignition Kill Switch.
Installation and Use Notes
Plug the 10-key connector into the engine’s kill-switch receptacle. Attach the lanyard clip to your life jacket D-ring or wrist strap before starting the engine. Inspect the lanyard before each outing and replace it if it shows any sign of wear, cuts or fraying. A damaged lanyard may not pull free reliably in an emergency.

Parts Desk Insight
This is the right choice when a customer needs a lanyard-only replacement for an existing 10-key kill-switch receptacle — common on Johnson, Evinrude and Yamaha outboards. If the customer isn’t sure which connector their engine uses, the Sea-Dog Universal Kill Switch with its panel-mount dual-circuit design is the safer recommendation. Always suggest replacing the lanyard whenever the switch itself is replaced.
