Product Details

The Sierra 18-3483 is a replacement water pump housing designed for marine outboard and sterndrive cooling systems. The water pump housing is a critical component of the engine's raw water cooling circuit, encasing the impeller and directing water flow to prevent overheating.

Over time, water pump housings can wear, crack, or corrode — reducing cooling water flow and increasing the risk of engine overheating. Replacing a worn or damaged housing restores proper water pressure and flow to keep your engine running at safe operating temperatures.

Key Features:

  • Direct replacement water pump housing for compatible marine engines
  • Engineered to meet or exceed OEM specifications and fitment standards
  • Manufactured by Sierra International, a trusted name in aftermarket marine parts
  • Designed to work with Sierra and OEM-compatible impellers, wear plates, and seals
  • Durable construction built to withstand the harsh marine environment

Sierra International has been producing premium-quality aftermarket marine replacement parts for decades, with a catalog covering thousands of components for major engine brands. The 18-3483 water pump housing is sold as a standalone replacement part and is ideal for use during a water pump service or rebuild.

The Mobil app SUCKS. After three (3) attempts to order this part, I had to wait until I was home to order it with my laptop.

Quick and easy.

Price was great although shipping was a little higher than other vendors. The status of the order online always showed as order passed to the warehouse so I had to call to find out what was happening with the order. Later that day the item arrived. Overall I'm happy with the service.

Not bad.. Except for one I was on your website the other day and I was going to order but I never did and I went on today to do that same order in the shipping prices Were double I don't understand why

good

Fast, easy & good prices

So far so good!
