Stay safe on the water with this floating kill switch lanyard!

It's a must-have for any boater—if you fall overboard, the lanyard pulls out and kills the engine, stopping the boat.

This one comes with two different keys to fit most outboard motors like Johnson, Evinrude, Mercury, Yamaha, and Honda.

The tether is made from TPU and PVC, stretches to about 53 inches (135 cm), and has a swivel snap hook that prevents tangles.

It floats, so it's easy to grab if it goes overboard.

Super easy to install, and it's a cheap piece of safety gear that could save your life.

Keep one on board as a spare or replace a worn-out original.
