ABSTRACT:
Inversion-protection of an outboard marine engine is achieved by fitting inside the engine casing watertight boxes to enclose the water-sensitive electrical components, i.e. the engine starter solenoid and the power pack. The starter motor spindle is provided with a shaft seal and the engine exhaust is fitted with an exhaust pipe in the form of a vertical hairpin or U-tube. The engine air intake box has fitted inside it a horizontally sliding valve that is automatically closed by a vertically-sliding weighted wedge engaging the valve rod.
