Product Details

The Quicksilver 99520 is an OEM molded coolant hose designed specifically for MerCruiser stern drive cooling systems. This genuine Mercury Marine replacement hose connects the heat exchanger to the regulator, providing a critical pathway for coolant flow in the closed-cooling circuit.

Key Features:

  • OEM Mercury Marine part number 32-99520 (also referenced as 99520)
  • Molded rubber construction for precise fit and durability
  • 3/4-inch tube outer diameter on both ends
  • Pre-formed shape eliminates kinking and ensures proper routing
  • Direct replacement for original equipment

This heat exchanger hose is engineered to fit MerCruiser 3.7L engines (1983-1989) and GM Big Block 454 V8 engines (1998-newer). The molded design ensures optimal coolant flow while withstanding the temperature extremes and constant vibration typical of marine environments. Genuine Quicksilver parts are manufactured to Mercury Marine's exacting specifications for reliable performance and long service life.

SO EASY

Great price and quick delivery.

good service and quick response

This is the only place I found that didn't ask if I wanted to talk to someone. Plus check out was easier then the rest.

Pretty smooth ordering and shipping process. Thanks.

I was very satisfied with the item we purchased and delivery time. The only thing I wish we could of done was add another item to our shipment before it was shipped. We I called customer service but was told that could not be done.
