MERCRUISER IB 160F° THERMOSTAT KIT
160°F thermostat kit with reassembly gaskets for Mercruiser injection or closed cooling FWC engines.

The thermostat is a key part of the marine engine's cooling system. It opens and closes based on coolant temperature, enabling quick warm-up and stable engine cooling.
A faulty thermostat can lead to overheating or inefficient engine performance. Replacing it helps extend your engine's lifespan and ensures reliable operation.
Our thermostats are compatible with Volvo Penta, Mercruiser, OMC, PCM engines and resist marine corrosion and temperature stress.
