A seal structure for placement at the joint between first and second cowl sections forms a seal between the cowl sections at two distinct locations. A resilient seal is formed at each sealing location, with one of the resilient seals being provided by a composite sealing construction. A flexible sealing strip for placement at the joint includes portions which form a pocket disposed between facing surfaces of the cowl sections, and a resilient cord placed within the pocket around the periphery of the joint. The pocket forming portions of the sealing strip can be moved to an open position so as to allow the strip to be satisfactorily stapled or otherwise connected to one of the cowl sections, as well as to allow placement of the cord within the pocket. The second resilient seal is provided by an enclosed air space disposed between another set of facing surfaces provided on the cowl sections.

In a two cycle internal combustion outboard marine engine (10) having vertical crankshaft (12) extending upwardly through a crankcase (14) and an alternator stator (6), and having a flywheel (4) secured to the top of the crankshaft, a louvered flywheel cover shroud (30) is provided over the flywheel and alternator. The louvers are provided by a plurality of spaced ramps (50, 52, 54, 56) extending along spaced inclined planes and defining vent openings (36, 38, 40, 42) therebetween exhausting air, to cool the alternator.

In a two cycle internal combustion engine (2), a fuel injection system is provided with a low profile compact intake manifold (22) mounted to the crankcase (8) by an adaptor plate (24) and defining an intake air flow path in a first direction (28) behind the manifold (22) through a gap between the manifold (22) and the crankcase (8) provided by the adaptor plate (24). Intake air then flows (32) into throttle bore passages (30) from behind the manifold and then reverses direction and flows through supply passages (34) having fuel injectors (38) and then into the crankcase (8). The passages share a common plenum (42) within the manifold. The fuel injectors (38), their electrical connectors (48) and a common rigid fuel supply rail (44) are all in the common plenum (42) entirely within the low profile manifold (22) and sealed from moisture and salt in a marine environment.

The invention provides a remote oil tank (19) to supply oil to an oil reservoir (29) mounted on a two-cycle, crankcase compression engine (10) such as used for outboard motors. Crankcase pressure may be used to pressurize the remote tank (19) to move the oil.
