PROBLEM TO BE SOLVED: To provide a fuel injection control device for an outboard engine to optimize the air-fuel ratio in operating the trim of the outboard engine. SOLUTION: In an outboard engine provided with a fuel injection type two-cycle engine, means to detect the engine condition such as the engine speed, the engine temperature, and the temperature of the sucked air are provided, the basic fuel injection amount is determined (S1) according to the information obtained from each engine condition detecting means, the fuel is fed (S7) for each cylinder, a trim angle detecting means of the outboard engine is provided, and the residual fuel amount in the engine is estimated (S3-S6) based on the trim angle and the engine condition obtained from each engine condition detecting means while the engine is operated at low speed. The basic fuel injection amount is corrected based on the estimated value. |
