You should change the oil in your Mercury outboard every 100 hours of use or at least once a year, whichever comes first. This is especially important for 4-stroke models, as regular oil changes keep the engine running smoothly and prevent wear.
If you’re using your outboard in harsh conditions, like saltwater or extreme temperatures, you might want to check the oil more frequently. Don’t forget to replace the oil filter during the service—it’s a small step that makes a big difference in engine performance and longevity.
