PROBLEM TO BE SOLVED: To prevent splashing of seawater on a fuel pump even when seawater flows inside the hull through intake air ducts by arranging the fuel pump to supply fuel to a fuel injection valve almost above an inboard opening of the intake air ducts. SOLUTION: In the hull 2 of a water autobicycle 1, the bathtub-shaped hull 3 and a cover-shaped deck 4 are watertightly joined together by a gunnel 9, and intake air ducts 12 and 13 to introduce outboard air into the hull 2 are arranged in a front end part and a rear end part of its deck 4. A fuel pump 49 is arranged so as to be positioned above air delivery ports 12a and 13a of the intake air ducts 12 and 13 of these front end part and rear end part. Therefore, splashing of water and seawater entering from the respective intake air ducts 12 and 13 on the fuel pump 49 can be avoided, and the occurrence of rust and corrosion in the fuel pump 49 can be prevented. As a result, a fuel supply to a fuel injection valve 45 can be accurately controlled, and the service life can be lengthened. |
