The Sierra 18-7824-2 is a spin-on marine oil filter engineered to protect V8 sterndrive and inboard engines through routine oil changes in the demanding marine environment. It is built with a heavy-wall, epoxy-coated steel canister for corrosion resistance, an anti-drain back valve that keeps oil in the filter between starts to reduce dry-start wear, and a high-efficiency filter media that meets or exceeds OEM filtration performance. The filter is field-tested and manufactured to meet or exceed OEM specifications, and it directly cross-references Mercury Marine 35-866340K01, making it a straightforward replacement for engines that call for that number.

This filter fits a wide range of V8 454/7.4L, 502/8.2L, and 496/8.1L marine engine models, including 400 TRS, 420, 425, 454 Mag. Alpha, 454 Mag., 454 Mag. EFI, 454 Mag. MPI, 465, 496 Mag., 496 Mag.
