Parts Desk Insights
Best suited for routine oil changes on Kohler marine generator sets commonly found on cruisers, trawlers, and liveaboard vessels. Kohler gensets require regular oil and filter changes — typically every 100–150 hours of operation — making this a steady service item for boats with onboard power. Kohler uses multiple filter sizes across its genset lineup; this filter (47-237822) is a different size from the Sierra 47-237823 and the Sierra 47-237824. Always confirm fitment against your Kohler generator model number before ordering. OEM part number: Kohler 47-237822 | Sierra 47-237822.
