Abstract: This disclosure relates to an air intake arrangement for a small boat including a hull, wherein the front end of a handle pole of the boat is supported pivotably on a horizontal shaft on the upper deck of the hull at a position which is on the longitudinal center line of the hull, and a handle lever to be held by an operator is attached to the rear end of the handle pole. An air intake port for taking fresh air into the engine compartment in the interior of the hull is provided on substantially the center line at a position corresponding to the lower side of the handle pole on the deck, and a lead-in opening for taking the air from the front of the boat and leading it into the air intake port is formed in the handle pole.

Abstract: A deck ventilator suitable for small vessels is formed as a low dome 12. Outside air may enter it through window 14 and then circulate around member 30, through orifice 22 and down duct 7 which pierces deck 4. Member 30 usually serves merely as a shield against spray, however if a surge of water enters compartment 18 the orifice 22 is closed by movement of member 30 which is slidably hinged to U-shaped rods 23. This closing movement results from the combination of the impact of the water on member 30 and the member's inherent buoyancy.

Abstract: An improved engine hood for jet ski type vehicles (boats). Air flow is greater and less water finds it's way into the engine compartment because of large ducts peripherally located, up and down in a horizontal plane around the interior of the hood, the down sections are water traps which drain outside and the previously horizontal ducts become snorkel type loops when the boat is capsized. The hood is removable and floats. The hood is characterized by a large rearwardly and forwardly louvered opening on the top, and a flexible exhaust conduit which appends the bottom extending down into the engine compartment.

Abstract: The vapor-sensing protective system of the present invention has a sensing device for fuel vapor which is mounted in an area where a fuel-powered engine is located. That sensing device develops a voltage within a predetermined range whenever it is operative and is properly connected in that system and senses for but does not detect fuel vapor; and that system responds to that voltage to permit starting of that engine. If that sensing device is not operative or is not properly connected in that system, it will be unable to develop a voltage within that predetermined range; and hence that system will prevent starting of that engine. If that sensing device is operative and is properly connected in that system and senses for and detects fuel vapor, it will develop a voltage above that predetermined range; and hence that system will prevent starting of that engine.

Abstract: Fuel tank breathing device for a small boat including a body and a handle column mounted on the body, a breathing conduit extending between a fuel tank in the body and a chamber defined in the column, the chamber in the column being provided with a ventilating and drain hole at its lower portion.

Abstract: An automatic digital safety system for controlling the starting and continued energization of one or more internal combustion engines within an engine compartment and for controlling the energization of exhaust blowers in fluid communication with the engine compartment. A guardian control unit disables starter motors and ignition coils of the engines, while simultaneously energizing the exhaust blowers for a first predetermined time interval after their ignition switches are turned ON. Blower sensor circuits sense the energized state of the blowers. Whenever the sensors indicate that the blowers are not energized when enabled, the system disables the engines. After the first predetermined time interval, the engine coils and starters are enabled and the blowers remain energized.
