Abstract
An outboard motor includes an engine. A cowling body defines an internal cavity in which the engine is enclosed. A partition member divides the internal cavity into a first cavity and a second cavity. The first cavity communicates with outside through a first opening for introducing ambient air into the first cavity. The second cavity encloses the engine therein. The partition member has a second opening through which the air in the first cavity moves to the second cavity. The cowling body and the partition member are made of a nonferrous metal. The partition member is adhered to the cowling body.

An outboard motor comprising an engine, a cowling body defining an internal cavity in which the engine is enclosed, and a partition member dividing the internal cavity into a first cavity and a second cavity, a first opening formed through the cowling body and opening into the first cavity for introduction of outside air into the first cavity, an inner pad affixed to an inner surface of an upper edge portion of the cowling body above the first opening, the second cavity enclosing the engine therein, the partition member having a second opening through which air in the first cavity is introduced into the second cavity, the cowling body and the partition member being made of a nonferrous metal, and the partition member being adhered to an inner surface of the cowling body with an adhesive.
A method of making an outboard motor, comprising providing an engine, providing a cowling comprising a top cowling body having an inner surface and an intake air opening formed through the cowling body, providing a partition member having an air duct opening formed therethrough, the partition member having a circumferential flange that is generally complementary to a portion of the inner surface of the top cowling body, applying an adhesive to the circumferential flange, adhering the circumferential flange to the inner surface of the top cowling body so that the flange fits substantially flush with the top cowling body and an intake space is defined between the partition member and the inner surface of the top cowling body, the partition member positioned so that the intake air opening opens into the intake space, and adhering an inner pad member to an inner surface of the top cowling member at or adjacent an upper edge portion of the intake air opening.
