A proximity key faub (however you spell it) is worse than dealing with a key. That is a disaster waiting to happen.

I noticed in one of the archive convos there was a lot of concerns with kids but I don't guess I follow. I think my daughter is just as capable of turning a key as she is pushing a button. Perhaps its more inviting? Also if the boat were to be started, then what? The only time I've had someone below the boat past the swim platform is to get a rope out from the prop. I understand the concern but I don't guess I see how the odds of someone being injured dramatically increased.
