Product Details

The Quicksilver 863631T1 Water Distribution Housing Assembly is a genuine OEM Mercury Marine cooling system component engineered for MerCruiser sterndrive and inboard gas engines. This housing serves as the central hub of the engine's freshwater cooling circuit, routing coolant flow to and from the fuel cooler, water circulating pump, thermostat housing, and exhaust elbow to maintain safe operating temperatures.

Designed for MerCruiser's standard cooling (multi-point drain) configuration, the 863631T1 features both 3-point and 7-point drain locations, allowing thorough winterization and engine block drainage without the need to remove block drain plugs or disconnect manifold hoses manually.

Key Features:

  • Genuine Quicksilver / Mercury Marine OEM factory part
  • Supports 3-point and 7-point drain configurations for standard cooling systems
  • Interfaces with the fuel cooler, water circulating pump, thermostat housing, and exhaust elbow
  • Replaces superseded part numbers: 863802T2 and 863444T2
  • Also cross-references drain plug part numbers: 22-806608A02 / Sierra 18-4226
  • Backed by Mercury Marine's 1-year factory warranty against defects and workmanship

This housing assembly is sold individually (each) and is the direct OEM replacement for worn, cracked, or leaking water distribution housings on applicable V6 and V8 MerCruiser engines. Always confirm fitment using your engine serial number prior to ordering.

Great price, fast shipping! Looking forward to receiving the part.

I bought 2 pairs of Stainless Steel polished 12x16 mud flaps. I looked at quite a few mud flaps for my Escalade EXT, and these were the only ones I could find that were not plastic or rubber. They are excellent, heavy duty, polished stainless flaps; and mounting hardware was included. They were well packed, shipped fast and at a very reasonable amount. Best of all they were $26.00 cheaper a pair. So I saved $52.00, got fast delivery, and got a very nice product.....Thank you Autoplicity; definitely saved in my favorites....Bill in Pittsburgh, Pa.

My ARB 50qt fridge/freezer arrived quickly and it was way cheaper than anywhere else. I was a little leery only because of that. However, I received the fridge and saved about $65 over even Amazon. No problems.

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.
