Abstract
An outboard motor includes a housing unit and an engine. The engine defines a first exhaust passage and a first lubricant passage. The first exhaust passage generally extends on a first side of the outboard motor. The first lubricant passage generally extends on a second side of the outboard motor opposite to the first side. An exhaust guide member is coupled with the housing unit to support the engine above the housing unit. An exhaust conduit depends from the exhaust guide member within the housing unit. The exhaust guide member defines a second exhaust passage connecting the exhaust conduit with the first exhaust passage. The second exhaust passage generally extends on the first side. A lubricant reservoir depends from the exhaust guide member within the housing unit. The exhaust guide member defines a second lubricant passage connecting the lubricant reservoir with the first lubricant passage. The second lubricant passage generally extends on the second side. The engine and the exhaust guide member together define a first water passage extending in the vicinity of the first and second exhaust passages. The engine defines a second coolant passage extending from the first coolant passage toward a location in the vicinity of the first lubricant passage.
