Avoid Outboard Corrosion
As an authorized dealer and service center for Yamaha, Honda and Suzuki outboards, and servicing customers in and around the Chesapeake Bay Region, we deal with our share of corrosion. One thing is for certain; no outboard engine is impervious to corrosion if neglected. It is very important to do what you can to prevent corrosion from affecting your investment.
Some things to be aware of:
Sacrificial Anodes – Most outboards today have sacrificial anodes both external and internal that require inspection and /or replacement. In salt water, especially in cases where the engine cannot be properly flushed with fresh water, these anodes should be checked frequently. In most cases, they’ll need replacing annually. Remember these anodes are in place to protect your engine from corrosion. Once they are gone, the corrosion starts to attack vital components and can become very costly quickly.
Prop Care – Don’t forget the propeller—it should be removed periodically (at least once a season). Check, clean and grease the shaft. Also check for and remove any old fishing line which can cut into prop shaft seals. When a propeller is not removed and its left for years, it is likely it won’t come off.
