Water jet propulsion boat

A water jet propulsion boat propelled by rearwardly ejecting water drawn through a jet pump driven by an engine, the water jet propulsion boat comprising:

• a fuel tank disposed in a boat body of the water jet propulsion boat through a supporting member to absorb vibrations;
• a fuel pipe extending from the fuel tank to the engine;
• a fuel pump unit including a fuel pump that is controlled by a control device to supply fuel from the fuel tank to the engine through the fuel pipe;
• and
• a fuel pressure detection device arranged to detect a pressure of fuel supplied to the engine by operation of the fuel pump;
• wherein
• the fuel pressure detection device is connected to the control device, and a fall sensor is disposed on the boat body and connected to the control device, wherein the control device stops the operation of the fuel pump if the fall sensor detects an overturning of the boat body and the fuel pressure detected by the fuel pressure detection device is out of the predetermined normal value range.
