Abstract
In engine temperature display device for a watercraft, an engine temperature data value is calculated based on a detection signal of a temperature of an engine of an outboard motor. The engine temperature data value is sent to an engine state display device installed in a watercraft by a LAN. A control portion of the engine state display device computes the engine temperature data value based on a plurality of threshold temperatures of a standard engine model stored in a nonvolatile memory, and converts the data value into a display data for indicating a temperature level among a plurality of temperature levels. The display data is displayed on a display device on the watercraft. An engine temperature data value calculating and sending device computes using a plurality of threshold values on an engine block wall temperature specific to an engine, and sends the appropriately converted engine temperature data value. The engine state display device for the watercraft propulsion unit can display an appropriate temperature level of the engine coolant temperature indicated for a model with higher engine coolant temperatures.
