SENSOR ARRANGING STRUCTURE OF ENGINE FOR SMALL PLANING BOAT

摘要

PROBLEM TO BE SOLVED: To provide a sensor arranging structure of an engine for a small planing boat for properly operating the engine by sufficiently taking a water splash preventive measure against engine control sensors. SOLUTION: The engine 20 for driving a jet propulsion pump is arranged in a hull 11 surrounded by a hull 14 and a deck 15. A horizontal partition assembly A extending in the longitudinal direction and extending in the almost horizontal direction in an engine upper part is composed of a throttle body 22 arranged on the intake air side of this engine 20 and a surge tank 23 continuing with this body, The engine control sensors 80 and 81 are arranged above this horizontal partition assembly. An intercooler 50 is arranged just under the surge tank 23. An intake pressure sensor 81 for detecting throttle downstream intake pressure is arranged near a head cover 26, and is installed in a state of floating from an upper surface of the throttle body 22.
