Corrosion Prevention for Outboard Motors
Posted by Balki Bartokomous on 17th Oct 2024
Corrosion is an issue that every boater must contend with. Because they are constantly exposed to the elements, outboard motors are especially prone to corrosion, which can cause extensive damage when left unchecked. This guide from Marine Parts Warehouse explains how to protect your outboard motor from corrosion, so you can maximize its lifespan.
The Signs of Corrosion
How do you spot the presence of corrosion on an outboard motor? Corrosion is often visible as a color change, but it can also manifest in other ways. Look out for these common signs of corrosion on your outboard motor: Discoloration or rust spots on metal surfaces. Pitting and flaking on exposed aluminum or chrome surfaces. Roughness, bubbling, or blisters on the surface of the paint. You should address any sign of corrosion on your outboard motor as soon as you notice it. The damage will only get worse if left untreated.
The Sacrificial Anode
A sacrificial anode is a metal rod or plate that attaches to your outboard motor. It's made of a material that corrodes more easily than the motor, and it's designed to draw corrosive elements away from the outboard motor itself.
To protect your outboard motor, you will need to check and replace the sacrificial anode periodically.
Flushing the Motor
Another way to reduce the risk of corrosion is to flush your outboard motor on a regular basis. This will prevent corrosive elements from building up inside the motor. The user manual provided with your outboard should contain instructions on how to flush the motor.
Cleaning and Polishing
Regularly cleaning your outboard motor will also help to prevent corrosion. Make sure you get rid of any dirt and salt deposits that have built up on the metal surfaces. The user manual will specify which cleaning products work best. Once your outboard is squeaky clean, give it a good polish. This will smooth out any light scratches on the surface that could be susceptible to corrosion.
Replacing Parts
If any part of your outboard motor is corroded, it will need to be replaced. Thankfully, you have found the best place to get quality used and new outboards parts! Feel free to send us a parts request to the team here at Marine Parts Warehouse.We hope you found this information helpful!
