Abstract: A reciprocating exhaust valve for a two-stroke internal combustion engine has a shaft for connection to a valve actuator, the shaft defining a reciprocation axis of the valve, the reciprocation axis defining a longitudinal direction of the valve; and a blade having: a first end having an arcuate edge, a second end connected to the shaft, two side portions, and a central portion. The blade has a first end portion adjacent the first end that includes a part of the central portion and of each of the two side portions. A width of the central portion is greater than a width of each of the side portions. In the first end portion, a thickness of the part of each of the two side portions is greater than a thickness of the part of the central portion.

Abstract: A marine engine for propelling a watercraft has a drive unit adapted to be pivotally connected about a steering axis to the watercraft, and a steering position sensing system. The steering position sensing system has a magnet housing operatively connected to the drive unit and having an arcuate portion, a magnet disposed in the magnet housing, a sensor housing adapted to be operatively connected to the watercraft and a sensor disposed in the sensor housing. The magnet housing and the magnet are pivotable about the steering axis with the drive unit and relative to the sensor housing. The arcuate portion of the magnet housing is spaced from the sensor housing. The sensor senses a magnetic field of the magnet to determine an angular position of the drive unit relative to the watercraft. A bracket assembly for mounting an outboard engine to a watercraft is also disclosed.

Abstract: A marine outboard engine includes an engine having a front, back, top and two lateral sides. A cowling, covering the engine at least partially, includes a central support structure fixedly connected to at least one of the engine, a swivel bracket, and an exhaust system. The central support structure extending across at least a portion of the front, top and back of the engine defines at least partially a space through which at least a portion of at least one of its lateral sides is accessible. The space is selectively covered by at least one side panel which is at least partially selectively connected to the central support structure and at least partially disconnectable therefrom to reveal the portion of the at least one of the lateral sides of the engine while the central support structure extends across at least the portion of the front, top and back thereof.
