Abstract

A water jet propulsion boat includes a main chamber rib dividing the inside of an oil pan into a main chamber where an oil suction port of an oil suction tube is arranged, and an auxiliary chamber outside of the main chamber. The main chamber rib covers the oil suction port at least from the front side and from the left and right sides of the oil suction port. The main chamber rib projects upward from the floor of the oil pan. An opening through which oil passes is provided in the main chamber rib only rearward of a rear edge of the oil suction port. The main chamber and the auxiliary chamber communicate with each other through the opening.
