I am getting better about keeping a hand on the go lever when running rivers but I still find myself slow about cutting power when I am going to go over an especially shallow gravel bar. My boat will skim through just a couple inches of water but I tend to vacuum up some gravel when that happens. I keep thinking that it would be sweet to have some sort of a button that would retard the timing and cut power down to an idle as I banged across the bottom and then once I was in good water the button could be released and the motor would burst back to life and off I would go. Kind of like the speed limiter in your car, or a rev limiter. Does something like that exist?
