Hi guys, I have a Navman sounder that has a small amount of green colored corrosion in both the plug and the lead. What is the best way to remove the green stuff and how do I keep it out? The sounder was in my tinny butit is now in my 1/2 cabin. The back of the unit got more than a few splashes on the old boat. But now it never gets wet, except when I wash it after fishing.
Cheers from OZ

clean with a Q-tip and contact cleaner as good as you can. Before you plug it back together put some synthetic dielectric grease on each pin and into each socket.

Thanks but the q tip wil only clean the outside of the female receiver on the sounder. Wil the dielectric grease dissolve the green corrosion?

Get yourself a can of CRC contact cleaner and spry it on then put on the dielectric grease

no dielectric grease will just stop it from getting worse. You might be able to buy a spray contact cleaner at the auto parts store. You wont get it perfect so just clean it the best you can then apply the grease

Gotcha. I was thinking along the lines of using a pipe cleaner or if a very small wire brush that looks like a pipe cleaner will get into the female receiver on the sounder. There is only some wrong water temperature readings that are way out that in on screen. Here the water temperature at the reef is from 22C in winter to 36C in summer. The sounder reads water temperature as high as 55C and 65C. My hope is that it's a bad connection from the corrosion causing the misread.

the above are correct, if you spray it in it gets most of the dirt out and the dielectric grease will seriously delay it from growing back. Don't use any hard objects like a wire brush or even a stiff bristle nylon to clean it as it will further damage the contact surface. These are usually tin plated (the good ones are gold) and if you remove the tin the copper in the brass will turn green a lot faster.
