Abstract: Two embodiments of improved compact outboard motors that are designed so that the power head does not encroach into the associated watercraft forwardly of the hull when the motor is tilted up about its tilt axis. In each embodiment, the internal combustion engine of the power head is located in such a way that it can be conveniently serviced and yet will note encroach when the motor is tilted up. In one embodiment, the engine is disposed with its output shaft extending transversely and its cylinders inclined rearwardly. In the other embodiment, the cylinders are aligned and extend vertically so that the engine output shaft extends perpendicularly to the associated hull.

Abstract: An outboard engine has a casing, an internal combustion engine with a water cooling circuit and an exhaust pipe. The exhaust pipe discharges exhaust gases into an expansion chamber, and gases from the expansion chamber are discharged into the body of water in which the vessel propelled by the engine floats. The exhaust pipe projects into the expansion chamber and has pores (perforations) near its outlet end. Coolant water is discharged into the expansion chamber and mixes with the exhaust gases. Gas flow through the pores discourages reverse flow of water droplets through the exhaust pipe to the engine cylinders.
