Five Oceans Marine FO1518 Emergency Kill Switch for 12V Boats & Jet Skis — Red Coil Lanyard & Floating Buoy

The Five Oceans Marine FO1518 emergency cut-off switch is a universal 12V kill switch that instantly stops engine power when pulled, and comes with a coil lanyard, snap hook, connectors, and a floating red buoy.

This compact emergency shut-off switch is built for small craft and motorized recreational vehicles where immediate engine shutdown can prevent injury or equipment damage. Designed for 12V systems, the FO1518 supports dual wiring configurations and installs inline with your ignition so the circuit is interrupted the moment the lanyard is released. Its components are tailored for water use — a floating buoy and bright red coil lanyard improve visibility and retrieval on the surface.

How does the kill switch stop my engine quickly?

The FO1518 interrupts the ignition circuit the instant the pull lanyard separates from the switch base. You can wire it either as "open to stop" or "close to stop," letting you match your vehicle's ignition type. The mechanical contact is direct, so there’s immediate loss of ignition when triggered.

• Rated 5A at 12V DC for small engines and accessories
• Two connection modes: open-to-stop or close-to-stop
• Installs inline with ignition wire for immediate cutoff

Will this switch work on my jet ski, boat, or ATV?

The FO1518 is designed as a universal safety switch suitable for many motorized vehicles including jet skis, small boats, ATVs, and motorcycles. Its compact mounting and standard wiring make it compatible with most 12V ignition systems, but always check your vehicle’s electrical specifications before installation.

• Works with boats, PWCs, ATVs, motorcycles, and similar 12V systems
• Mounting hole fits 5/8" (16 mm) panels
• Includes two wire connectors for straightforward hookups

What parts are included and how do they help on the water?

The kit contains everything you need for a basic emergency cut-off setup, so you won’t need to source separate hardware. The red coil lanyard keeps the cord compact on deck, while the buoy keeps the disconnected end afloat and visible, speeding recovery and reset after an incident.

• Red coil extendable lanyard reduces deck clutter and stretches when needed
• Floating red buoy keeps the lanyard end visible and retrievable on water
• Snap hook and wire connectors included for easy attachment and wiring

How do I install and maintain this emergency cut-off switch?

Installation is quick for anyone comfortable with basic electrical tasks: drill the 5/8" (16 mm) mounting hole, connect the wires per your ignition type, and secure the switch. Routine checks ensure reliability — inspect wiring, the snap hook, and the buoy for wear before each season.

• Mounts through 5/8" (16 mm) panel hole; tighten with supplied hardware
• Use provided connectors for a secure electrical connection
• Periodically test the cutoff and inspect components for corrosion or damage

Who is this for: The Five Oceans FO1518 is for recreational boaters, personal watercraft riders, and off-road enthusiasts who want a straightforward, reliable emergency engine cut-off. It suits owners of small 12V-powered craft who prefer a compact, easy-to-install safety switch complete with a visible floating lanyard and basic wiring accessories. Ideal as a replacement or backup switch for rental fleets, individual watercraft, or any rider seeking quick engine shutdown capability without complicated electronics.
