Everyone has been helpful here so I am very thankful- most seem to know their stuff. I bought a new to me a 22' 1973 HiLiner earlier in the summer. I plan on fishing near coastal here in Southern MA during the Fall Striper run. Is there an aftermarket lanyard I can use to kill the engine should I go over the side for any reason? I know I would have to customize something the age of the boat but am looking for ideas here.The engine is a 1998 Mercruiser 4.3 L 4 BBL.
