A marine propulsion device comprising an internal combustion engine including a coolant conduit having an upstream conduit portion, a downstream conduit portion, and a passage portion extending between the upstream portion and the downstream portion. The engine also includes a mechanism for controlling the flow of coolant through the coolant conduit, the controlling mechanism including a valve assembly located in the passage portion and including therein an opening, a temperature responsive mechanism located in the valve assembly and movable relative to the opening for opening and closing the opening in response to temperature variations, a first housing including a passageway communicable between the downstream conduit portion and the opening, a second housing including a passageway communicable between the upstream conduit portion and the opening, and threaded portions on the first housing and the second housing for releasably connecting the first housing and the second housing to form an enclosure containing the temperature responsive mechanism.

Marine engine cooling system valve assembly

An air silencer for an internal combustion engine including a fuel hose and an intake manifold supporting a carburetor, the carburetor including an end including a carburetor intake. The air silencer comprises a base member including a first opening, a second opening adapted for extension therethrough of the carburetor, and an opening for passage into the air silencer of the fuel hose, and the base member is mounted on the intake manifold independently of the carburetor. The air silencer also comprises a cover member removably mounted on the base member, and a baffle member removably mounted between the base member and the cover member to form a silencing chamber between the cover member and the baffle member, the baffle member including an opening adapted to communicate with the carburetor intake, and a silencer tube communicating between the first opening in the base member and the silencing chamber.
