Abstract
PURPOSE: To contrive to simplify construction and facilitate production by a method wherein an engine mount box at a rear part of a surfboard is composed of three cases, i.e., upper, middle and lower cases, and the case are interconnected in such a manner as to form a support for a crankshaft, a sealing part, a cooling and an exhaust system and the like.
CONSTITUTION: An engine chamber 12 is formed at a ridge part 6 of the rear part of the surfboard 1, and the engine 14 is mounted on the square engine mount box 13 which is placed at the bottom of the chamber 12. The box 13 has a stacked construction consisting of the upper case 43, the middle case 44 and the lower case 45 which are integrally connected to each other. A spirally shaped case 52 enclosing an impeller 51 of a water jet propulsion device 50 and a jet nozzle 53 are formed through the interconnection of the middle and lower cases 44, 45. A supporting pipe 57, cooling-water passages 42, 60, 62, an exhaust passage 29 and the like are also formed through the connection of the stacked cases 43, 44, 45.
