Product Details
This 130°F thermostat kit is an aftermarket replacement for selected Mercury, Mariner and Force 2-stroke outboard cooling systems. It is designed to help maintain the thermostat's specified operating temperature and restore proper cooling-system regulation when the original thermostat or related service parts are worn, damaged or corroded.
The kit is listed for the Mercury Marine OEM reference 14586A7. The GLM catalog identifies the corresponding 130° thermostat, gaskets and poppet kit as GLM 13201. Always verify the complete engine model, year and serial number before ordering.
- 130°F thermostat service kit for selected 2-stroke outboards.
- Includes the thermostat and associated gasket, poppet and housing-service components shown below.
- Helps support correct engine warm-up and cooling-system temperature control.
- Aftermarket replacement; not an original Mercury Marine component.

Installation Notes
- Allow the outboard to cool completely and follow the service manual's safety procedure.
- Disconnect the battery or isolate the starting system where required by the engine manufacturer's procedure.
- Close or remove the cooling-water supply as appropriate and place a drain pan beneath the service area.
- Locate the thermostat housing and record the orientation of the cover, thermostat, poppet and related components.
- Remove the housing fasteners and carefully take out the old thermostat and gaskets.
- Clean the mating surfaces without scratching the housing or cylinder-head sealing area.
- Install the new components in the same orientation as the original parts, using the correct gasket at each location.
- Reinstall the cover and tighten the fasteners to the torque specified in the engine service manual.
- Restore the cooling-water supply, reconnect any isolated electrical components and run the engine using the correct flushing or test procedure.
- Check for leaks and confirm that the engine reaches its normal operating temperature without overheating.
Troubleshooting & FAQ
How do I confirm that this kit fits my engine?
Match the engine brand, model, horsepower, stroke, year and serial number with the parts diagram or service manual. Also compare the original thermostat and housing configuration with the kit contents. The OEM reference 14586A7 is useful for cross-checking, but it should not replace complete engine identification.
What does 130°F mean?
130°F is the thermostat's stated temperature specification, approximately 54.4°C. It is not a universal operating-temperature guarantee for every engine or operating condition.
What are common signs of thermostat trouble?
A thermostat stuck open may prevent the engine from warming properly, while a thermostat stuck closed or a restricted cooling passage may cause overheating. Inspect the water-flow system and related cooling components before replacing parts.
Is this an OEM part?
No. This is an aftermarket replacement kit associated with Mercury Marine OEM reference 14586A7. Mercury, Mariner and Force are manufacturer or engine-family references and do not indicate that this product is manufactured by those companies.
Should the gaskets be replaced during thermostat service?
Yes. Reusing compressed, torn or corroded gaskets can cause leaks or improper sealing. Use the correct supplied gasket for each mating surface and follow the engine manufacturer's service procedure.
Safety & Important Information
- Verify the engine model, year, serial number and parts-diagram reference before ordering.
- Do not use a 130°F thermostat where the engine requires a different temperature specification.
- Never work on a hot engine or run an outboard without an adequate cooling-water supply.
- Use the manufacturer's torque values and installation procedures; professional installation is recommended when required.
- Inspect the housing, poppet passage, cooling passages and sealing surfaces for corrosion or blockage during service.
