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