Indmar 160 Degree Marine Thermostat

Indmar 160 degrees marine thermostat part # 985009. Used on the majority of indmar like the Indmar Monsoon, Indmar MCX, Indmar Assault, Indmar LT3R, Indmar Hammerhead, and many others. One exception is the Corvette LT1 engine, use Indmar part # 986034 for that engine.

Older engines equipped with a 143 degree thermostat can use the 160 degree thermostat. An engine running at 160 degrees will benefit better performance because fuel will atomize easier helping the engine run more efficiently. Make sure to perform a tune if you change from a 143 to a 160-degree thermostat. 

Thermostats can fail and what you use to replace it with is important. The only thermostat that will function properly is the original equipment.
