If it is broken, replace it. If you find it a pain to insert the clip, just buy a new clip and leave it installed all the time'
Of course the smart thing would be to have the switch and use it with the tether but many boaters don't.
A new law, enacted a year or so back, mandates that boats up to a certain length have to have a 'kill' or emergency cut off switch. If your vessel did not originally have one, you don't have to add one but if your vessesl had one, you can not remove it.
In addition according to the law, there are times where you must be using the ECO for example attaching the lanyard to yourself.
I leave the spiral cable on the small fork in the killswitch dangling, that makes it easier to put it on when I am under engine.
Hoever, I bought a Fell Marine MOB+ to get rid of the lanyard, but will leave the kill switch operational.
