Patent ID: 8321080

Claim:
An outboard motor comprising: an engine control unit including a memory device and a control portion; wherein the memory device is arranged to store a plurality of threshold values for an engine temperature of a standard engine; the control portion is arranged and programmed to receive a detection signal corresponding to a temperature of a non-standard engine that runs at a normal temperature that is a higher temperature or a lower temperature compared to a normal temperature of the standard engine, to determine an engine temperature level based on the plurality of threshold values and the detection signal, to convert the detection signal into an appropriate engine temperature data value based on the engine temperature level, and to send the appropriate engine temperature data value from the outboard motor to a display device on a watercraft; when the normal temperature of the non-standard engine runs higher than the normal temperature of the standard engine, the control portion is programmed to convert the detection signal into the appropriate engine temperature data value by decreasing the temperature corresponding to the detection signal; and when the normal temperature of the non-standard engine runs lower than the normal temperature of the standard engine, the control portion is programmed to convert the detection signal into the appropriate engine temperature data value by increasing the temperature corresponding to the detection signal.
