- 7.4 Merc w/Bravo III Drive
I have a BravoIII so I need to do what I can to protect against corrosion. I've seen a lot of info floating around but decided to call Mercury for the straight scoop.
- Don't add a second Mercathode if you only have on engine, it's counter productive. One will do the trick.
- If your setup did not come with a anode on the prop nut don't add one. Too many zincs will begin to have the out-drive casing protecting the zincs.
- If you are painting your out-drive per paint manufacturers directions whether, Interlux , Petitt or whoever paint the bare metal that is normally covered by the inner prop. This is hard to explain. If you remove both props you will see about 5 inches of unprotected metal, Mercury does not paint it from the factory. I'm not referring to the shaft. This exposed metal should be painted especially if your in saltwater.
- Get a Merchathode test probe & Digital Multimeter, learn how to use it and check for stray electricity often.
