How to Prevent Corrosion on Your Boat

Boats are a magnet for corrosion — the combination of metal parts and prolonged exposure to water creates the perfect conditions for rust. While most marine components are sealed and shielded, tiny leaks can corrode the surface over time. 

With a proactive approach, you can prevent corrosion and keep your most important systems in top shape. Use the following tips and don’t hesitate to contact the service department experts at Bill Howich RV & Marine. Our dealership is located in Campbell River, British Columbia, and we also serve those in Courtenay and Nanaimo.

Clean the Green Wire

The "green wire" is the wire that prevents you from getting shocked when the electrical system malfunctions. This component, which is usually called the grounding wire or bonding wire, often passes through damp or leak-prone sections of the boat. 

To prevent corrosion, clean the wire and apply a protectant to ward off moisture. If you're unfamiliar with electrical work, it's a good idea to hire a professional for this process.

Monitor the Fuel Shut-Off Valve

The fuel shut-off valve prevents gas from getting into the bilge of your boat. If it's rusted, you run the risk of fuel leaks, fire, and explosions. 

To ward off these issues, make sure to inspect and move the valve lever. This prevents corrosion from building up. It also helps you spot and repair potential problem areas before they become dangerous.

Inspect and Clean Light Wire Connections

Your boat's navigation lights are a crucial safety feature, especially if you like to boat in low-light conditions or after sunset. The delicate wire connections are vulnerable to corrosion; it doesn't take much to break the connection and turn out the light. 

Once or twice a year, examine the wiring. If you see signs of corrosion, clean it off and replace damaged connections.

Lubricate Throttle and Shift Cable Jackets

Find the throttle and shift cables on your boat — are they covered with a plastic jacket? If so, tiny cracks in the plastic can allow moisture to reach the metal cables. Over time, even a small amount of water can corrode and snap the cable. 

Every season, or any time you experience stiff shifting or throttle movement, lubricate the ends of the cables to repel water. If you see cracks, add new plastic shields.

Check Sailboat Rigging

The rigging components on a sailboat can accumulate corrosion, often in hard-to-see areas. When you winterize and de-winterize the boat, check the chainplates and rigging toggle for signs of corrosion. It's helpful to use a magnifying glass or a zoom lens to find tiny cracks. If you see a problem, hire a professional to inspect, remove, and replace the components. 

Corrosion is an insidious issue for all boaters. With constant vigilance and regular inspections, you can stop rust before it damages your boat.
