A sensor arrangement structure for an engine for a personal watercraft for preventing an engine controlling sensor from being splashed with water so that the engine operates appropriately. An engine for driving a jet propulsion pump is provided in a watercraft body surrounded by a hull and a deck with a throttle body and a surge tank contiguous to the throttle body being provided on the intake side of the engine and forming a horizontal partition assembly A extending in a forward and rearward direction and extending in a substantially horizontal direction at an upper portion of the engine. A sensor for controlling the engine is disposed above the horizontal partition assembly. An intercooler is disposed just below the surge tank. The intake pressure sensor for detecting the intake pressure on the downstream side with respect to the throttle valve is disposed adjacent to a head cover and is attached in a state wherein it is spaced away from an upper face of the throttle body. |
