Nice innovation, but it's not going to do anything if you're simply thrown from your seat and/or rendered unconscious if you remain in the boat. It's highly likely that the steering wheel is the last thing you're hanging onto as you get thrown, so a jerk to the side on the wheel on your way out/down and you'll still have a boat running/turning at WOT without an operator.

They need to use a proximity sensor, not a water sensor, to make it work in such situations.

See my simple, effective way to comfortably where a wired lanyard in the "do you always wear your kill switch lanyard" thread in the safety forum.

My .02 cents

My thoughts exactly.

Now ya see.... I thought it was to shut down if your way from the drivers seat. not what I thought it was. thanks for the link BY U BOY

I also suspect that at 100 MPH by the time it sends the signal the boat will be out of range.
