The link to Kill Switch Keys With Lanyard has been copied
Be prepared. Always carry a spare kill switch key. Most marinas don't stock replacement keys, so if you lose or break your kill switch key, your much-deserved day out on the boat can be quickly ruined. This lanyard comes with 7 keys to fit most BRP, Johnson, Evinrude, Mercury, Yamaha, Honda, Tohatsu, Nissan, and Suzuki kill switches. It's equipped with rust-free stainless steel crimps and a swivel snap hook to prevent tangles. Don't leave the dock without it!
