Severe electrolysis on lower units

[edliden]

I have a Sea Ray Sundancer 280 with twin outdrives. Over the past boating season I have noticed severe electrolysis of the lower units. I know this is caused by current leakage from the electrical system. Can any one tell me how to go about finding and stopping the current leakage?

Thanks, schematic. I will look into the galvanic isolator idea. I'm willing to try anything if it will help!

It might not be electrical leakage from your boat, of course, if you are in a marina. If it's a marina environment, I would check with owners of boats in adjoining slips to see if they are having problems (and maybe find a tactful way to suggest they make sure their electrical systems are up to snuff.)
