Abstract
An electrical system for an engine of the type utilized to power an outboard motor is disclosed. The engine has a body with a crankshaft rotating therein. At least one fuel injector supplies fuel to the engine for combustion. The electrical system includes an electronic engine control unit for controlling at least the fuel injector based upon one or more sensed conditions. The electrical system also includes at least one sensor for providing data regarding one or more conditions. Preferably, at least an air pressure and intake air temperature sensor are provided. The sensors are mounted to a portion of the engine body adjacent the crankshaft, preferably via a vibration isolated bracket, for improving sensor accuracy and reliability.
