Abstract
A control for a marine propulsion unit including a water propulsion device powered by an engine through a transmission. The transmission has forward, neutral and reverse positions. The engine has at least one combustion chamber, an air and fuel supply system, and at least one ignition element corresponding to the combustion chamber for igniting an air and fuel mixture supplied to the combustion chamber. The control is arranged to delay the firing of the ignition element when the engine is idling from a normal firing timing, and arranged to advance the firing of the ignition element if the engine speed rapidly reduces and the position of the transmission is changed from neutral to reverse or forward.
