摘要： An oil jet device for piston cooling in which no press-fitting device is required, and the O-ring is prevented from being broken. A filter plug is inserted into an oil passage opening from the crank journal of a crankcase toward the side of the lower portion of the cylinder, and the crank journal is sealed by a plain bearing being abutted against the filter plug. The oil passage is formed by ring-shaped feed paths formed in the ring-shape on the bearing portions on the plain bearing and the crankcase.

摘要： To make an intake apparatus and the inside of a boat body less likely to be contaminated with oil and to make an electric apparatus less likely to suffer from any trouble. A four-cycle engine having a head cover in which a breather exit is formed is carried in a boat body, and an oil storage portion when the boat is capsized is formed from the head cover. An upper face of the head cover is positioned close to and extends along a ceiling of the boat body, and the breather exit is provided above an upper face of oil stored in the head cover when the boat is capsized. A connection portion of the intake apparatus to a breather pipe is disposed below the breather exit. The head cover has a water drain path formed therein which connects to a plug mounting-dismounting hole and is opened to a peripheral face of the head cover rearwardly of the hole with respect to an advancing direction of the boat body. A water drain flow path is formed at a lowermost end portion of a bearing surface for a plug.
