ABSTRACT:
An outboard motor intake port system includes an internal cover mounted, from the inside, on an engine cover to form an intake chamber between the internal cover and the engine cover. The internal cover is integrally provided with a bottom plate portion facing the inner face of an upper part of the engine cover, a front wall portion extending upward from a front edge of the bottom plate portion and connected to the inner face of the upper part of the engine cover, and a pair of tubular portions extending upward from the bottom plate portion. The pair of tubular portions are arranged side by side so water that has entered the intake chamber via an intake port passes through the tubular portions. A pair of drain holes for discharging water are formed in the engine cover and communicate with the left and right front parts of the intake chamber.
