What Kind of Maintenance Does an Outboard or MerCruiser Motor Need?
Routine maintenance is critical for keeping your Mercury outboard motor and MerCruiser sterndrive in top shape. Typical needs include regular oil changes, spark plug replacements, and gear lube checks.
In saltwater conditions, flushing your engine after every use is a must to avoid corrosion. Inspecting the fuel system for leaks or blockages also helps prevent long-term damage. Following Mercury’s recommended maintenance schedule is the best way to avoid costly repairs and keep your engine at its best.
How to Do Maintenance on an Outboard or MerCruiser Motor
- Oil Changes: Use the right oil to reduce friction and keep the engine cool.

Staying on top of these tasks helps prevent costly repairs and keeps your Mercury motor or MerCruiser sterndrive running smoothly.
How Often Should You Service a Mercury Outboard or MerCruiser Motor?
Service frequency depends on usage and conditions. Mercury recommends servicing at least once a year or every 100 hours of operation—whichever comes first. In saltwater or harsh environments, more frequent service is advised.
Each service should include oil replacement, fuel filter changes, and inspection of key components like the propeller, water pump, and lower unit. For convenience, PowerBoatSupply.com offers maintenance kits with all the essentials for both outboards and Mercury MerCruiser parts.
