What is a MerCathode controller?
The MerCathode system provides automatic protection against galvanic corrosion. A solid‑state device that operates off a vessel’s battery, the MerCathode system provides protection by impressing a reverse blocking current that stops the destructive flow of galvanic currents.
Does the MerCathode system work?
The Mercury Precision MerCathode system provides automatic protection against galvanic corrosion. It is a solid-state device that operates off a boat’s 12-volt battery and provides protection by impressing a reverse blocking current that stops the destructive flow of galvanic currents.
How do you prevent corrosion on outdrives?
Preventing Damage to Your Underwater Fittings
- Check your outdrive for signs of corrosion several times each season.
- Make sure you have the recommended number and type of anodes (aluminum works best for the vast majority of cases) and make sure they are in contact with what they are protecting.
How do you reverse galvanic corrosion?
Here’s how you reverse it, after a piece of metal has become corroded: 1. Set up an electrolyte bath in a non-conductive tub by filling it with water, and adding one tablespoon of electrolyte (washing soda works well) per gallon of water. Give it several minutes to dissolve, stirring as necessary.
Should I Store boat with outdrive up or down?
The outdrive should always be stored in the down position. This relaxes the bellows so they will last longer.
Can you keep a stern drive in the water?
To keep water from entering the exhaust hub when storing your sterndrive, leave it in the “down” position or use a waterproof cover.
What causes corrosion on an outdrive?
You might not think that a boat’s power connection could have anything to do with a corroding outdrive, but it can; aside from missing anodes, it is probably the most common cause of severe corrosion. Boats plugged into shore power share the green ground wire with every other boat in the marina that is plugged in.
Which Mercruiser outdrive is best?
Alpha One Outdrive Most Popular Sterndrive for Power Boats Cited by Mercury Marine as “the most popular sterndrive in the world”, the Alpha One outdrive system is used for single or twin engine applications. The Alpha One has earned a reputation as a value-priced outdrive propulsion system that delivers reliable speed.
Can galvanic corrosion reversed?
It sounds nuts – can you really reverse the corrosion process? Yep, you bet. Fighting corrosion is a never-ending battle for all boaters, especially those in saltier waters.
Can corrosion be reversed?
Unfortunately, the damage caused by rust cannot be reversed. Once the metal has flaked away, you can only stop any more rust from occurring or replace it.
Can I leave my boat in the water all year?
A protected boat can theoretically sit on the water all year long, or even longer than that, but this is usually not encouraged due to the damage and deterioration that can occur over time. If your boat is already damaged, you may need to sand the hull, refinish it, and apply a protective coating.
Should you leave your boat motor in the water?
It’s best to tilt your outboard up when leaving your boat in the water to prevent marine growth from forming and from corrosion eating away at its metal parts.
