Product Details

The Quicksilver 864920A02 Fresh Water Closed Cooling (FWC) Kit is a genuine OEM Mercury/MerCruiser assembly kit designed to convert or service a MerCruiser sterndrive engine to a closed cooling system. Closed cooling systems protect the engine by circulating fresh water coolant through the block rather than raw (salt or lake) water, dramatically reducing internal corrosion and extending engine life.

This kit replaces legacy part numbers 864920A 1 and 864895A1, making it the current OEM-specified replacement for those earlier assemblies.

Key Features:

  • Genuine OEM Quicksilver / Mercury Marine part — not aftermarket
  • Closes the cooling circuit to protect the engine block from raw water corrosion
  • Includes all necessary hardware and components for a complete closed cooling service
  • Replaces superseded part numbers 864920A 1 and 864895A1
  • Sold as a single kit (quantity = 1)

Supersedes: 864920A 1, 864895A1

Using a closed (fresh water) cooling system is one of the most effective ways to extend the service life of a MerCruiser engine, particularly in saltwater or brackish environments. Always verify fitment using your engine's serial number prior to ordering.

<br>Good prices - seemed to be the best online! Shipping seems normal. / Handling time seemed delayed. If quality is good will order from again.

You had what I was looking for at the best price and with quick shipping, I couldn't go wrong!

using amazon pay is easy I was not able to track the UPS shipment until the day of delivery. Maybe the number did not scan correctly at the time of shipment. Customer service did show it was shipped on time, and it arrived quickly.

Couldnt find the item by navigating the page, had to google search it then it came up, but otherwise easy purchase.
