420021001 An emergency cord with many different keys to fit almost all Yamaha and PWC's. A luxurious soft padded wrist seal feels comfortable on the skin and keeps you safe during a wild ride. Product feels solid, floats, whistles, and will fit any watercraft and Yamaha outboard steering in any case; no doubt on more boats. You can choose whether you want the Velcro cord (very strong - gives more confidence than the original Yamaha neoprene strap you get with a Waverunner) around your wrist or ankle, or the clip that cord to your body, instead hanging directly from your vest, so that you have the least possible impact in every situation.
