Show original supplier description
The Sierra Marine 18-7897 oil filter is specifically engineered to excel in the demanding conditions of extreme marine environments. It incorporates an anti-drain-back valve to ensure oil stays in the filter and lubricates the engine immediately upon startup, preventing dry starts. This filter meets or exceeds original equipment quality standards. Constructed with premium grade materials, the 18-7897 offers robust filtration for 4-cycle marine engines. It features a standard 3/4" x 16NPT thread size, making it a direct replacement for various Johnson/Evinrude and Suzuki part numbers, including 5033919, 778887, and 16510-82703. The filter is also epoxy coated for enhanced corrosion resistance in saltwater environments, a crucial feature distinguishing it from automotive filters whose cases can be thinner and prone to rust. This oil filter is suitable for specific marine applications, including some 200HP and 225HP engines from 2004-2006. Always verify fitment with your specific engine model to ensure proper compatibility.
