  • Patent number: 10287963
    Abstract: An outboard motor includes an engine, an engine cover with which the engine is covered, an intake pipe disposed between an outer surface of the engine and an inner surface of the engine cover, and a battery. The engine includes a piston that reciprocates rectilinearly and a crankshaft that rotates around a crankshaft axis extending in an up-down direction. The intake pipe is connected to a first outer surface of the engine along the crankshaft axis, and supplies air to the engine. The battery is disposed between a second outer surface of the engine, which is different than the first outer surface, and the inner surface of the engine cover.

  • Patent number: 6975936
    Abstract: A malfunction diagnosis system is provided to aid a technician or engineer in diagnosing an internal combustion engine. The diagnostic system comprises an electronic control unit that is operatively coupled to a data storage device and to one or more engine sensors. The electronic control unit is configured to collect data from the one or more engine sensors, compare the collected data with predetermined engine parameter values, and store the collected and compared data in the data storage device in various formats. A computer is selectively coupled to the data storage device. The computer program is configured to display specific sets of data and to clearly display any faulty engine parameter values resulting from the collected data comparison.

  • Patent number: 6846207
    Abstract: A watercraft is equipped with an outboard motor and an inboard local area network (LAN) that communicates control signals to the outboard motor. An outboard motor operating device retains the ability to operate the outboard motor even if part of the inboard LAN develops an abnormality. In particular, a control signal that controls the outboard motor and a conditional information signal that indicates a condition of the watercraft are transmitted by independent cables that are mutually separated. Even if the cable for transmitting the conditional information signal or equipment connected to the cable develops an abnormality, transmission of the control signal for controlling the outboard motor is not hindered since the control signal is on the other cable, which is not affected by the abnormality. The conditional information signals are processed to generate and display return-to-port warnings based on the watercraft conditions and other operator issued constraints.

  • Publication number: 20040100369
    Abstract: A service alarm system for a boat propulsion unit monitors a lubricant service life. The system informs the watercraft operator when the lubricant is no longer suitable to provide proper lubricating properties for the boat propulsion unit. The alarm system informs the operator by sounding an audible alarm or illuminating a visual alarm through at least one light. By informing the operator inadequate lubrication properties, the user can perform proper service of the watercraft to ensure safe and enjoyable watercraft operation.

  • Patent number: 6647769
    Abstract: A diagnostic system is provided for aiding a technician or engineer in verifying that a fuel injector in a fuel injected engine is operating properly. The diagnostic system comprises a controller operatively coupled to an actuator for the fuel injector and to a fuel pressure sensor. The controller is configured such that, during a fuel injector test, the controller outputs a signal to the fuel pump so that pressurized fuel is supplied to the fuel injector. After the pressurized fuel is supplied to the fuel injector, the controller outputs a signal to the actuator to operate the fuel injector for a predetermined amount of time. The controller is also configured such that after the predetermined amount of time the fuel pump is turned off.
