Abstract
An engine for an outboard motor includes an oil filter. A first oil passage has a communication duct disposed at a position lower than that of the oil filter and communicating with a crank chamber. The communication duct is closed by a drain valve that can be opened and closed manually. Opening the drain valve allows the oil accumulated in the first oil passage to flow down into the crank chamber through the communication duct.
