This water temperature sender with its 5/8 X 18UNF thread will fit a WaterMota engine if your temperature sender is fitted in the WaterMota Thermostat Housing if you do not have a thermostat or into the WaterMota Water Temperature Sender Core Plug at the rear of the engine in the block which provides a more accurate reading.
This water temperature sensor reads 240 ohms of resistance to 23 ohms. There are many different resistances used for temperature senders so it is important to match the gauge with the correct sender. The resistance used for this sender is based on the European standard, however, there are multiple interpretations of the European standard, therefore we recommend purchasing the specific Freeman Smiths Electrical Water Temperature Gauge with Chrome Bezel for this sender.
