The Kwik Tek Outboard Kill Switch Keys is a universal kill switch which serves as a spare should you ever lose your main kill switch. If you lose or break your kill switch key, for whatever reason, you won't be able to start your engine. Most marinas don't stock replacement keys, so your much-deserved day out on the boat will be ruined. This lanyard has 7 keys to fit most all BRP, Johnson, Evinrude, Mercury, Yamaha, Honda, Tohatsu, Nissan and Suzuki kill switches. It's equipped with a swivel snap hook to prevent tangles, and rust-free stainless steel crimps. Don't leave the dock without it!
