    Abstract: A number of embodiments of outboard motors having catalytic exhaust systems. In each embodiment, an expansion chamber is formed in the drive shaft housing and the exhaust gases are delivered to the expansion chamber from an exhaust pipe that extends at least in part through the expansion chamber and which terminates at its lower end in the lower portion of the expansion chamber. A catalyst bed is positioned at the upper end of the expansion chamber and beneath the engine and through which the exhaust gases must pass for discharge through a further exhaust conduit which extends at least in part through the expansion chamber and which terminates at an underwater exhaust gas discharge. Embodiments are depicted with banks of cylinders having exhaust manifolds that are disposed either adjacent each other, in which case the catalyst bed is comprised of two portions disposed transversely outwardly of the exhaust pipes or wherein the exhaust pipes are spaced from each other and the catalyst bed is comprised of two portions disposed transversely from each other and between the exhaust pipes. An embodiment is also shown having an exhaust pipe with a catalyst bed that surrounds it.

    Abstract: An outboard motor having an improved catalyst system for treating the exhaust gases regardless of whether they are delivered to the atmosphere through an above the water exhaust gas discharge or a below the water exhaust gas discharge. When the engine is operating at high speeds, the exhaust gases only have surface contact with the catalyzer bed and do not flow through it while under slow speeds the exhaust gases flow through the catalyzer bed.

    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.

    Abstract: A crankshaft lubricating oil passage structure of a V-shaped engine includes a main oil passage and a sub oil passage. The V-shaped engine includes a pair of banks. The pair of banks includes cylinders and is disposed in a V shape with respect to the crankshaft. The V bank angle as an included angle of the cylinders of the respective banks is set at a narrow angle. The main oil passage is provided between the pair of banks in the cylinder block or the crankcase. The sub oil passage extends from the main oil passage to the bearing portion of the crankshaft and guides lubricating oil to the bearing portion. The main oil passage is formed by connecting divided passage portions that are divided partway in an axial direction by an oil passage connection member that is a separate member from the cylinder block or the crankcase.
