Abstract
An outboard motor comprises, in an installed or mounted state, an engine holder, an engine located to an upper portion of the engine holder, a drive shaft housing located to a lower portion of the engine holder for housing a drive shaft extending downward from the engine, and an oil pan formed to the engine holder, the oil pan being provided with a wall section to which steering brackets are secured through upper mounts. A first seal member is disposed at a mating surface portion of an upper surface of the drive shaft housing and a lower surface of the oil pan and a second seal member is disposed at a mating surface of an upper surface of the oil pan and a lower surface of the engine to thereby expose the drive shaft between the first and second seal members.
