摘要： In an apparatus for controlling operation of an outboard motor having a shift lever used to change a shift position between an in-gear position that enables driving force of an internal combustion engine to be transmitted to a propeller by engaging a clutch with one of a forward gear and a reverse gear and a neutral position that cuts off transmission of the driving force by disengaging the clutch from the forward or reverse gear, it is configured to detect a throttle opening of the engine; detect a speed of the engine; calculate a change amount of the detected engine speed; and conduct driving force decreasing control to decrease the driving force of the engine based on the detected throttle opening, the detected engine speed and the calculated engine speed change amount.

摘要： The invention provides a fuel supply device, which is possible to prevent undesired water entered into a fuel path from remaining therein with a simple arrangement. A fuel supply pipe for supplying fuel to each of the fuel injection valves of an engine disposed with a plurality of cylinders in a vertical direction includes a fuel path in longitudinal direction, a smaller diameter portion formed perpendicular to the fuel path and continuous with a fuel injection valve mounting hole, and a cap attached to a lower end of the fuel path. The cap is arranged so that the upper end of its protruding portion is positioned at the same or nearly same level as that in height of the smaller diameter portion. Thus, the water entered in the fuel supply pipe is exhausted through the smaller diameter portion without delay.

摘要： In an air/fuel ratio control system for an outboard motor engine, a learned correction coefficient KTIMn used in open-loop control for correcting a basic fuel injection amount to be supplied to the engine, is updated only when the manifold absolute pressure PBA (indicative of engine load) is within a predetermined range relative to the engine speed NE concerned. As a result, the air/fuel ratio can be accurately controlled to one other than the stoichiometric air/fuel ratio, even when an O2 sensor that produces an output whose property only changes near the stoichiometeic air/fuel ratio is used.
