I have seen temp sensors do this. In tight turns the water flow can miss the sensor and it trips a signal. My RXT-X does it under aggressive turns as well.
This happens to me sometimes, especially with less than half a tank of gas and doing doughnuts. The sharp turns tricks your fuel sensor into thinking that the fuel tank is empty and notifies you for that split second that you don't have gas because your boat is on its side. Perfectly normal just gravity being gravity.
