Abstract: A marine motor assembly for a watercraft includes a housing, a motor, a housing gearset, a gearcase gearset and a propulsion device. The housing includes an upper housing portion and a gearcase connected to the upper housing portion. The gearcase includes a gearcase chamber, and a gearcase fluid port disposed on an exterior surface of the gearcase. The housing also includes a housing chamber spaced from the gearcase chamber, a housing fluid port that is disposed on an exterior surface of the housing and that is fluidly connected to the housing chamber, and a fluid conduit that fluidly connects the gearcase chamber to the housing chamber. The housing gearset is disposed in the housing chamber. The gearcase gearset is disposed in the gearcase chamber. A method for changing a lubricant in the marine motor assembly via the gearcase fluid port and the housing fluid port is also disclosed.

Abstract: An outboard engine assembly has an engine unit including an engine unit housing, an internal combustion engine disposed in the engine unit housing, the engine defining at least one combustion chamber, a gearcase connected to the engine unit housing, and an exhaust system, the exhaust system including an idle relief passage fluidly communicating with an exhaust passage, the idle relief passage having an idle relief outlet, the idle relief passage extending through the engine unit housing for supplying exhaust gases from the at least one combustion chamber to an exterior of the engine unit housing via the idle relief outlet, the idle relief outlet being disposed vertically higher than the exhaust outlet and vertically lower than a waterline when the outboard engine assembly is mounted to a watercraft and the watercraft is at rest, and a propulsion device operatively connected to the engine.
