Five Oceans Marine Emergency Kill Switch FO1518 — 12V Universal with Red Coil Lanyard & Floating Buoy

The Five Oceans Marine Universal Emergency Cut-Off Switch (FO1518) is a compact 12V kill switch that stops engine power instantly using a coil lanyard, snap hook and floating red buoy for water and powersport safety.

This universal emergency cut-off switch is built for boats, jet skis, ATVs, motorcycles and other motorized equipment where a quick engine shut-off can prevent injury or equipment damage. The FO1518 offers dual-circuit wiring for either ignition‑kill or magneto‑kill setups, a compact mounting footprint, and a bright floating buoy to help recover the lanyard after use. Rated at 5A for 12V DC, it installs inline with your ignition and comes with the connectors and hardware you need to get started.

How does this kill switch stop my engine quickly?

The FO1518 interrupts the ignition circuit immediately when the lanyard is pulled, cutting power to the engine. It supports two wiring modes—open-to-stop or close-to-stop—so it works with different ignition systems and magneto setups.

• Dual circuitry: wire for ignition kill or magneto kill.
• Installs directly into the ignition line for immediate shutdown.
• Rated 5A at 12V DC for common small-engine systems.
• Mounting hole: 5/8" (16 mm) to fit compact dash spaces.

What comes in the box and how is it used on the water?

The kit includes a red coil extendable lanyard with a snap hook, two wire connectors and a red buoy that floats to keep the lanyard visible and retrievable. Clip the snap hook to your person or PFD; if you are separated from the helm, the lanyard pulls free and the switch kills engine power.

• Red coil lanyard stretches with movement, then retracts to reduce snagging.
• Floating buoy keeps the lanyard on the water surface for quick recovery.
• Snap hook provides a secure attachment point to clothing or gear.
• Includes two electrical connectors for straightforward wiring.

Will this fit my craft and how easy is installation?

The FO1518 is designed as a universal retrofit and fits most small craft, personal watercraft and powersports vehicles. Its small mounting hole and inline wiring make it suitable for dashboards, tillers and compact consoles; wiring follows the open-to-stop or close-to-stop configuration based on your ignition system.

• Universal design for boats, jet skis, ATVs, motorcycles and other motorized vehicles.
• Compact mounting: requires a 5/8" (16 mm) hole for installation.
• Simple wiring: two-connection configuration with included connectors.
• Works with standard 12V DC small-engine electrical systems.

How durable and visible is the lanyard and buoy?

The coil lanyard is made to extend and retract, reducing drag and snag risks while staying out of the way. The bright red buoy floats and increases visibility on the water so you can locate and reattach the lanyard quickly after an emergency stop.

• Bright red buoy improves visibility and retrieval on the water.
• Coil design minimizes loose cord and snagging hazards.
• Snap hook offers a reliable, fast connection to clothing or PFDs.
• Supplied connectors simplify a secure electrical connection.

Who is this for: The Five Oceans FO1518 emergency cut-off switch is suited for small-boat owners, PWC riders, ATV and motorcycle operators, rental fleets and anyone wanting a straightforward safety shut-off. It’s particularly useful for users needing an easy-to-install, compact kill switch with a floating lanyard for visible recovery on the water. If you operate 12V-powered small engines and want a proven, no-frills safety line interlock, this kit provides the core parts and wiring flexibility to protect riders and gear.
