This Sierra coiled lanyard, MP40990, is made for the 4097 switch. It is meant for older boats that lack an engine cut-off: pull the lanyard and the engine stops, which prevents runaway situations. The kit comes with illustrated instructions, the coiled lanyard and all the parts needed to install it. The stated purpose is to stop the engine instantly from a single pull.
Our take
A single pull on the coiled lanyard stops the engine, which is the point of fitting it to an older boat with no cut-off. Everything for installation is included, but it is described for the 4097 switch, so confirm yours is that model.
