Repair a leaking thermostat with an OEM gasket

Cooling system components are subjected to countless heat cycles. As a result, thermostat gaskets can break down and leak. Replacing the gasket at the first sign of a leak can prevent corrosion to surrounding areas. Mercury Marine thermostat gaskets are manufactured to factory specifications. Boaters and technicians can have confidence of quality and performance by using original manufacturer parts.

Available for many thermostats on different engine applications, reference your repair manual or the table below to confirm the proper part number for your inboard or outboard engine.

Or call 1-800 BOATING with your serial number, or make, model and year of your engine and speak to an expert to find the right gasket.

Key Features

  • OEM part ensures proper fit and function
  • Restores seal of thermostat to engine block connection
  • Available for many MerCruiser applications.
