I considered doing this, but never got around to it. I love the look of the Autoloc buttons. If I were to do it, I would buy the module that allows the push button to start and stop the engine, as it seems stupid to me to have a button to start, but still have to flick a switch for 'on' and 'off' every time. In a car this might be OK, but with a boat that you are constantly starting and stopping it just would become cumbersome.
