At that price I think a bit of string will be fine as well................

Aaahhh, that explains the strange noise I heard just before twelve today - it was the sound of lots of boat owners sucking in a sharp intake of breath!

Holy crap that's expensive, think i'll stick with my piece of string! Great idea but at that price, not a hope in hell

I found this on ebay. It has pretty much what is needed. I'm sure it'll not take too much to make it pull in a relay to kill the engine. Adjustable range too. I'm gonna get one to check it out.
