Abstract: A marine engine assembly for mounting to a watercraft is disclosed. The marine engine assembly has an engine unit, an exhaust system fluidly and a propulsion device. The engine unit includes an engine unit housing, an internal combustion engine and an air intake assembly. The air intake assembly, at least one combustion chamber, and the exhaust system together defining at least in part a gas flow pathway. A sealing valve is provided in the gas flow pathway. The sealing valve has an open position permitting flow of gas therethrough. The sealing valve has a closed position preventing flow of gas therethrough for sealing a portion of the gas flow pathway downstream of the sealing valve from a portion of the gas flow pathway upstream of the sealing valve. An air pump is configured for supplying air to the gas flow pathway downstream of the sealing valve.

Abstract: A marine motor assembly for mounting to a watercraft is disclosed. The marine motor assembly has a motor unit including a motor unit housing, a motor, a propulsion device, an air pump fluidly communicating with an under-housing volume of the motor unit housing, a pressure sensor for measuring air pressure in the under-housing volume, and a control unit communicating with the air pump and the pressure sensor. The control unit is programmed for controlling the air pump for changing air pressure in the under-housing volume, and monitoring change in the air pressure for a predetermined amount of time for confirming that the motor unit housing is water-resistant, or that the water resistance of the motor unit housing is compromised. A method for testing a water resistance of a motor unit housing of a marine motor assembly is also disclosed.

Abstract: An exhaust valve system for a two-stroke internal combustion engine having: at least one exhaust valve movable between open and closed positions; an actuator for moving the at least one exhaust valve; a valve position sensor; a controller communicating with the actuator and the valve position sensor. The controller being programmed for: controlling the actuator to attempt to move the at least one exhaust valve to a desired one of the open and closed positions; determining if the at least one exhaust valve has failed to reach the desired position based on the position of the at least one exhaust valve sensed by the valve position sensor; and controlling the actuator to move the at least one exhaust valve to an intermediate position when the at least one exhaust valve has failed to reach the desired position.
