Installation Guide

  1. Ensure the engine is completely cool before beginning any work. Disconnect the battery to prevent accidental starting.
  2. Locate the thermostat housing on your Chrysler or Force outboard motor. It is typically positioned near the cylinder head.
  3. Remove the thermostat housing cover by loosening the mounting bolts or screws. Carefully lift the cover away.
  4. Remove the old thermostat and inspect the housing for corrosion or debris. Clean the mounting surfaces thoroughly with a scraper and solvent.
  5. Remove and discard the old gasket and seal. Ensure no remnants remain on the mating surfaces.
  6. Install the new F84504 thermostat seal into the designated groove or position in the housing.
  7. Place the new F528068 110-degree thermostat into the housing, ensuring proper orientation (check valve direction if marked).
  8. Position the new 517-31 gasket onto the thermostat housing, aligning all bolt holes correctly.
  9. Reinstall the thermostat housing cover and hand-tighten the mounting bolts. Torque bolts to manufacturer specifications in a crisscross pattern.
  10. Refill the cooling system with the appropriate coolant or water mixture as specified in your engine manual.
  11. Reconnect the battery and start the engine. Allow it to reach operating temperature and check for leaks around the thermostat housing.
  12. Monitor engine temperature during initial operation to confirm the thermostat is functioning correctly.

Troubleshooting & FAQ

Q: How do I know if this thermostat kit fits my Chrysler or Force outboard?
A: Check the compatibility table above to confirm your engine model, HP, and year match the listed applications. This kit is designed specifically for motors with a poppet relief valve in the block—verify your engine has this feature before ordering.

Q: What are the signs that my thermostat needs replacement?
A: Common symptoms include engine overheating, running too cool (below normal operating temperature), poor fuel economy, or steam/coolant leaks from the thermostat housing. If your engine temperature is erratic or outside the normal range, inspect the thermostat.

Q: How often should I replace the thermostat on my outboard motor?
A: Thermostats should be inspected annually and replaced every 2-3 years or as needed based on performance. If you notice temperature irregularities or the thermostat fails a boiling water test, replace it immediately regardless of age.

Q: Can I reuse the old gasket and seal when installing this thermostat?
A: No, always use the new gasket (517-31) and seal (F84504) included in this kit. Reusing old gaskets can result in coolant leaks and improper sealing, leading to engine overheating or damage.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

So cute and so worth it!
Size: 3 Little Kid, Color: Turquoise
AMAZING for my 7 year old daughter. She can tie shoes but I no longer have to wait on her to do so. It takes 2 seconds for her to put these on and she says that they are super comfortable. We have been to Silver dollar City multiple times and she never complains about her feet hurting! They are easily washed in the washer. They hold up great. I think they are very much worth the money! Fit normal.
