Parts Desk Insights
Best used as a routine maintenance replacement filter during oil changes on compatible marine engines. Verify fitment against your engine's service manual or Sierra's application guide before ordering — Sierra part numbers are engine-specific and this filter may not interchange with other Sierra oil filter SKUs. Pair with the correct marine-grade engine oil for your engine's specifications.
