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 a trouble. An intake apparatus of a four cycle engine cooperates with a small boat body to reduce the possibility of oil contamination or possible electrical damage. The four- cycle engine 20 having a head cover 40 in which a breather exit 41 is formed is carried in a boat body 11, and an oil storage portion when the boat is capsized is formed from the head cover 40. An upper face 43 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 51 of the intake apparatus 50 to a breather pipe 42 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.
