Product Details

The Quicksilver 14586A3 Thermostat Kit is a genuine OEM replacement thermostat designed to maintain proper operating temperature in select Mercury and Mariner 2-stroke outboard engines. Engineered to Mercury Marine's exact factory specifications, this kit ensures your engine runs at the correct 120°F (49°C) temperature for optimal performance, fuel efficiency, and long-term reliability.

Key Features:

  • 120°F (49°C) thermostat — factory-specified operating temperature for compatible engines
  • Genuine OEM Quicksilver part — direct factory replacement, not aftermarket
  • Complete kit — includes the thermostat and all necessary gaskets for a thorough service
  • Direct-fit installation — no modifications required for compatible models
  • Protects engine health — correct thermostat temperature prevents carbon buildup and overheating

Cross-Reference Part Numbers:

  • Mercury/Quicksilver: 14586A3, 14586A 3, 75692A9, 75692A10, 75692A11
  • Sierra Marine: 18-43052
  • GLM: 13121
  • Recmar Marine: REC14586A3

Using the correct OEM thermostat is critical for engine performance. An improperly rated thermostat can lead to carbon buildup, reduced fuel efficiency, and premature engine wear. Trust the Quicksilver 14586A3 to deliver a precise, factory-quality fit every time.

Unbelievably fast shipping

great pricing

Easy and straightforward

Package arrived on time, and quality was good. Shipping and taxes all included. Its really worth the money spent. Thank you Andy

Thanks

easy ordering. 15 secs and i was done.

Great price, would purchase from Autoplicity again.

Not only was it the lowest price on the net, the Amazon sign-in saved valuable time and ensured they were reliable. What impressed me even more was the delivery time, I've already gotten it! I did NOT expect to receive my air filter this quickly!

Quick checkout easy fast

great

Ordered EBC brake rotors on Tuesday afternoon and received notification on Thursday morning that they have already been shipped. Fast order processing and a low price, what more could I ask for? When I need to do the front brakes, I will be coming here first.

Great service

Great communication, Great prices! They beat all the competitors hands down on price for my cold air intake order #18986. Quick shipping and they are now in my favorites for places to look for automobile needs. The only thing I would like to see them change is the speed of their website.

Very easy to use and great prices

thank you

great prices

Always great parts.

Regarding order 708:<br><br>I would order from Autoplicity again without hesitation. The order process was simple and I received my order within a few days. I am very happy with my purchase.

Good deal
