I have seen these on big power boats before. I also saw a guy take a header out of his Mach II bass boat on Racoon. He was ****ed up but had his vest on. Boat went on a joy ride until it found land. Thats why they are there. The throttle does not care in most of these boats.They've been standard equipment on boats under 26' for years. Sounds like this law will just mandate their use vs letting the clip and cord hang on the switch.
