ABSTRACT:
An engine control for an internal combustion engine powering a water propulsion device of an outboard motor propelling a watercraft is disclosed. The engine control changes one or more combustion condition parameters of the engine based upon changes in one or more operating conditions of the motor or watercraft which affect the exhaust back pressure of the exhaust in the exhaust system of the engine. The operating conditions may include the motor trim angle, watercraft speed, watercraft posture, transmission position, and engine mount height. The engine control changes a combustion condition parameter such as the air/fuel ratio, spark ignition timing, or fuel injection timing to optimize the engine operating performance based upon the detected operating parameter.
