<P>PROBLEM TO BE SOLVED: To provide a water jet propulsion boat capable of suppressing air suction of an oil pump while suppressing an increase in the number of parts. <P>SOLUTION: In this water jet propulsion boat, a main chamber rib 32 divides the inside of an oil pan 31 into a main chamber R1 where an oil suction port 35a of an oil suction tube 35 is arranged, and an auxiliary chamber R2 outside of the main chamber R1. The main chamber rib 32 covers the oil suction port 35a at least from the front side and from the right and left sides of the oil suction port 35a. The main chamber rib 32 projects upward from a bottom surface of the oil pan 31. In the main chamber rib 32, openings 43a and 43b through which the main chamber R1 and the auxiliary chamber R2 are communicated with each other and oil passes are formed on only a rear side from a rear end of the oil suction port 35a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
