Abstract
A marine propulsion device comprising a propulsion unit including a rotatably mounted propeller, and an engine drivingly connected to the propeller and comprising an engine block, a spark timing mechanism, a fuel supply mechanism, a control lever supported by the engine block, a mechanism for displacing the fuel supply mechanism from an idle setting to a full speed setting in response to movement of the control lever from an idle position to a full speed position, and a spark timing control mechanism for permitting movement of the control lever from the idle position to a first intermediate position without displacing the spark timing mechanism from a minimum spark advance setting, for displacing the spark timing mechanism from the minimum spark advance setting to a maximum spark advance setting in response to movement of the control lever from the first intermediate position to a second intermediate position, and for displacing the spark timing mechanism from the maximum spark advance setting to an intermediate spark advance setting in response to movement of the control lever from the second intermediate position to the full speed position.
