Product Details

The Quicksilver 71587A10 is an OEM Fresh Water Cooling (FWC) coolant overflow recovery kit designed for MerCruiser sterndrive and inboard engines equipped with closed cooling systems. This genuine Quicksilver replacement kit restores the coolant recovery system that captures overflow coolant as the engine heats up and returns it to the cooling circuit as the engine cools down, helping maintain proper coolant levels and protecting the engine from overheating.

In a closed cooling (FWC) system, coolant expands under heat and is directed from the pressurized fill neck into the overflow recovery reservoir. As the engine cools, vacuum draws that coolant back into the system. Replacing a damaged or missing recovery kit ensures this cycle functions correctly and prevents coolant loss overboard.

Key Features:

  • Genuine OEM Quicksilver part — manufactured to Mercury Marine original equipment specifications
  • Designed for MerCruiser fresh water cooling (FWC / closed cooling) systems
  • Includes overflow recovery reservoir and associated hardware as a complete kit
  • Restores proper coolant overflow capture and return function
  • Direct OEM replacement — no modification required
  • Backed by Mercury Marine's 1-year factory warranty against defects and workmanship

Part number 71587A10 is sold as a complete kit. Always verify fitment using your MerCruiser engine serial number before ordering.

Fast,quick and secure. Paid with amazon.

So far so good

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.

Your site looks professionally constructed and has an easy to understand interface.
