Product Details

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

Designed as a direct-fit replacement, this assembly features a 3 and 7-point drain configuration for standard cooling systems, making winterization and routine maintenance straightforward. It is the factory-authorized successor to earlier part numbers 863802T2 and 863444T2.

  • Replaces superseded part numbers: 863802T2 and 863444T2
  • Backed by Mercury Marine's 1-year factory warranty against defects in materials and workmanship

Very easy mobile site!

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.
