Abstract: A watercraft and a marine engine assembly for pivotably mounting to a watercraft about a tilt-trim axis are disclosed. The marine engine assembly includes an engine unit including: an engine unit housing; an engine disposed in the housing; and an exhaust conduit disposed in the housing, an exhaust inlet defined by the exhaust conduit being fluidly connected to the engine, the exhaust conduit extending forward and upward from the exhaust inlet and then subsequently extending downward and rearward to an exhaust outlet. The marine engine assembly also has a driveshaft operatively connected to the engine and a propulsion device operatively connected to the driveshaft. A center of mass of the engine is disposed below the tilt-trim axis at least when the driveshaft is vertically oriented.

Abstract: A watercraft and a marine engine assembly for mounting to a watercraft are disclosed. The marine engine assembly includes an engine unit including: an engine unit housing being sealed such that water in which the engine unit housing is immersed is impeded from entering the engine unit housing; an engine in the housing; and an air intake assembly in the engine unit housing which forms a conduit between an exterior of the engine unit housing and the engine, the air intake assembly defining an inlet fluidly communicating with exterior air, the engine unit housing defining at least one aperture aligned with the inlet, the air intake assembly defining at least one outlet fluidly connected with the engine intake, the air intake assembly being sealed such that surrounding fluids within the engine unit housing are impeded from entering the air intake assembly; and a propulsion device operatively connected to the engine.
