I have a Story and a Request for Help:
Over the last two seasons, I have had two killswitch failures at sea. The switch/es were aftermarket additions to a Yanmar diesel. They looked like the picture below:
The clip is holding the button out when fitted. This makes a circuit and when removed the button drops in and the circuit breaks - activating the kill/stopping the engine. In my case my original switch failed at sea, about 150 meters off a rocky lee shore - fortunately in good conditions but we did get to the point where the hook was about to go over the side. Luckily a bit of "knob twiddling" on my part remade the connection and we motored out of danger where I fitted a cable tie that widened the gap a bit and we RTB.
I had the switch replaced but the replacement went the same way the following season - this time half way across the Irish Sea but I was able to sort it underway - knowing the "way of the knob" by then.
Barrus have now supplied a different type of switch now (Thanks Scott
) and it's a push down type - release to kill. No offence intended to any of the suppliers, but all the switches are the cheapest, nastiest bits of flim-flam imaginable. TBH, I haven't seen any better on sale anywhere myself so no complaints from me! But it really is a two dollar switch - maybe a one dollar switch!
