An outboard motor includes the direct fuel injection system. The outboard motor also includes an ECU that monitors various engine operating conditions and controls various engine operating parameters that are at least partially dependent on the positioning of the transmission. In instances in which the transmission is positioned in a neutral location, the load is decreased and therefore the ECU outputs one set of parameters. In similar low-speed operations, when the transmission is placed in a drive arrangement, the ECU outputs a second set of parameters due to the increased load. Several control routines are disclosed which facilitate low-speed operation, over-rev limiting, and engine warm-up.

1. An outboard motor comprising an engine and a propulsion unit, said engine having an output shaft and said propulsion unit comprising a propeller shaft, a shiftable transmission being interposed between said output shaft and said propulsion unit, said shiftable transmission being adapted to move between a neutral state and a drive state whereby movement of said output shaft is removed from said propeller shaft when said shiftable transmission is in said neutral state and movement of said output shaft is transferred to said propeller shaft when said shiftable transmission is in said drive state, said outboard motor further comprising a control unit adapted to control at least one operating parameter of said engine, a shift detector being in electrical communication with said control unit and being adapted to output a signal indicative of a shift state of said shiftable transmission, an engine speed sensor being in electrical communication with said control unit and being adapted to output a signal indicative of an engine speed, a throttle angle sensor being in electrical communication with said control unit and being adapted to output a signal indicative of a throttle angle, said control outputting a first signal if a first input condition is satisfied and outputting a second signal if a second input condition is satisfied.
