Product Details

The Sierra 18-7758 is a premium marine oil filter specifically engineered for Mercury 4-stroke outboard engines. This canister-style filter is designed to withstand the harsh marine environment while providing superior engine protection and filtration performance.

Key Features:

  • Heavy-wall steel canister with epoxy coating for maximum corrosion resistance in saltwater and freshwater environments
  • High-efficiency filter media that meets or exceeds OEM filtration standards
  • Anti-drainback valve prevents oil from draining back into the crankcase during engine shutdown, eliminating dry starts
  • Bypass relief valve ensures continuous oil flow even if the filter becomes clogged
  • M22 x 1.5 thread specification for secure installation
  • Backed by Sierra's industry-leading warranty

OEM Cross References: Replaces Mercury Marine 35-877761K01, 35-877761Q01, Quicksilver 35-877761Q01, Mallory 9-57822, and EMP 35-57822. This filter is engineered as a cost-effective alternative to OEM filters without compromising quality or performance.

Sierra has been a trusted name in marine aftermarket parts for over 58 years, manufacturing premium engine and drive components specifically designed for the demanding marine environment.

Exact replacement

They met all my expectations, which isn't a simple thing to do. I will visit the site again for future purchases.

Everything was great and smooth. No issues. Great job. Everything was easygoing and quick shipping.

Will be back!

I had ordered some CM-19546-A2 (friction-modifier for posi-traction differentials with carbon-fiber clutches) from CJ Pony Parts, and it arrived broken and had all leaked out. I spent $25.42 for nothing, and they still have not responded to my complaint. I bought 2 bottles from THMotorsports in hopes that ONE would arrive undamaged. They arrived in a box, not a bubble mailer like CJ, and both bottles were intact and undamaged. If you're going to buy specialty automotive fluids online, THMotorsports is the better place to do so.

Great, on time delivery
