SX leg cosmetic maintenance

[shepnuts]

My SX leg started corroding under the paint and spread quick. What can I do to stop/repair this mess? I appreciate any help on the matter.

To start with, make sure all the bonding wires on the drive and transom shield are in place. There are also connections inside the boat.
Make sure you have the correct anodes or the electronic setup is working if installed.
Next, how about a hint as to the year and type water you run in (salt/fresh), engine model or serial number.

Ok I thought it might have something to do with that. The leg and engine are 07' models, the engine is a 3.0l GLP-E. I run strictly in the Pacific Ocean.

Re: SX leg cosmetic maintenance

I checked the bonding wires and I found one that was not connected to a hose clamp on the exhaust bellows. I also found one inside the boat on the transom shield that looked a bit corroded. Could these two things be the source of the problem? Both the transom shield and the leg seem to have extensive corrosion under the paint. This has only happened since I owned the boat in the last three years. I have taken the leg off once and serviced the bellows, I'm sure this is when one of the bonding wires was left off. The anodes seem to be in decent enough condition, maybe I'm wrong... Should I continue to look or have I found the problem, what is your take? I feel like the only way I could know if I'm right is if it doesn't continue to corrode, however, that will be hard to gauge at this point. Any advice is greatly appreciated.

The serial number on the leg is 4151139853



And just to understand the bonding system more clearly, a negative wire is attached to the transom shield, then each component (pivot housing, trans shield, outdrive, etc.) are connected to each other with a grounding strap?
