Sierra Oil Filter 18-7910-1 for Yanmar 3YM20, 3YM30 Diesel Engines

The Sierra 18-7910-1 is a spin-on oil filter engineered for Yanmar 3YM20 and 3YM30 marine diesel engines. It is built with a steel housing and a 20mm x 1.5 thread, and it is furnished with an anti-drain-back valve that keeps oil from draining out of the filter and back into the crankcase during engine shutdown, which helps eliminate dry starts and protects critical engine components at the next start-up. Sierra filters are tested and approved for use with ethanol-based fuels and are built to meet the demands of modern high-tech, high-performance marine engines.

This filter is a direct-fit replacement designed to install with confidence in place of the original equipment filter, and it is cross-referenced to Yanmar part numbers as well as several well-known aftermarket filter brands, so boat owners have multiple sourcing options for the correct filter. Routine oil and filter changes are one of the most important maintenance tasks for a marine diesel engine, and using a filter sized and rated correctly for the application helps protect the engine against contaminants during normal operation.
