Coolant Temperature Sensor - Indmar Engine Temp Sender

Keep your Indmar-powered boat running safely and efficiently with this screw-in coolant temperature sensor (engine temp sender). It monitors engine coolant temperature and sends the signal to your gauge/ECU so you can spot overheating early, protect your engine, and maintain reliable performance on the water. Designed in a compact brass, automotive-style threaded body for a secure fit and consistent readings.

• Product type: Coolant temperature sensor / temperature sender
• Application: Indmar marine engines (verify fitment by thread/connector and your engine model)
• Construction: Brass threaded body with hex for easy installation
