Don't Go Boating without a Spare: Why Two Kill Switch Lanyards are Mandatory
Why You Need Two Universal Kill Switch Lanyards
A universal kill switch lanyard is a small safety device that can stop your engine in real time if you fall. It’s basic marine safety and low-cost safety equipment that works across typical working conditions on the water. This guide explains why you need one, even if you think you don’t, and how to choose the right key.

What is a Kill Switch (Engine Cut-Off) Lanyard?
A kill switch lanyard—also called an engine cut off or engine cut-off switch lanyard—clips the operator to the ignition circuit. If you fall or move too far from the helm, the clip pulls free and the engine stops in real time. This simple safety precaution prevents an uncontrolled boat.
Use it on every trip—short or long—across normal work environments at sea (spray, vibration, movement). It’s a proven way to improve safety for you and your crew.
Regulations & Safety Standards
In France, Division 240 (art. 240-2.01) requires a functional emergency stop device on outboards with tiller or remote steering, and on PWCs over 4.5 kW (6 HP). In the United States, similar safety standards exist. Always follow your flag-state rules for marine equipment and marine technology.
Why You Need Two Lanyards
If the operator goes overboard, the attached lanyard stays with them—no one can restart. Keep a second safety lanyard on board so crew can restart quickly and recover the person in the water in the event of an emergency. Store the spare visibly and tell everyone where it is.
Universal Compatibility
The Baywatt universal kill switch lanyard includes 7 interchangeable keys that fit most major outboard brands: Yamaha, Suzuki, Honda, Mercury, Johnson, Tohatsu, Nissan, Kawasaki (also Evinrude) and Baywatt electric outboard motors. One spare that works across almost every engine.
How to Choose the Right Key
- Identify your engine brand/model (Yamaha, Suzuki, Honda, Mercury, Johnson, Tohatsu, Nissan, Kawasaki).
- Match the insert shape from the 7 keys to your engine cut-off switch.
- Attach to your PFD/belt using the snap hook so it triggers in real time if you lose balance.
- Keep a spare onboard for long term reliability in the event of an emergency.
Not to Be Confused with Fall Protection Lanyards
This marine safety lanyard is for engines. It is not a work-at-height PPE and does not replace fall protection lanyards, shock absorbing lanyards, a harness anchorage point, or other personal safety devices used around hazardous materials. For industrial safe working, follow your safety standards.
Materials, Durability & Working Conditions
- Spiral cable (PU) with memory, acting like a light shock absorber during movement.
- Corrosion-resistant ABS/Nylon hardware and snap hook for marine working conditions.
- Extendable length up to ~1.2 m for mobility at the helm.
- Tool-free install; works with common engine cut-off switch standards.
- Built for long term use in saltwater work environments.
Don’t Compromise With Safety
Carry two universal kill switch lanyards: one in use, one spare. A few euros for real peace of mind and to improve safety in real time.
