Galvani Corrosion?

[Fully_Loaded1]

I have a 24 ft Chaperall with twin 115 Yammys. My startboard motor is getting the little galvani corrosion spots on the lower unit and tower housing. I have 2 batteries and the starboard motor battery is isolated from all the accessories it is just used to start the one motor any ideas?

Re: Galvani Corrosion?

how is the paint? scratches nicks? what are you parked next to on the stbd side? do you have trim tabs, are anodes fitted to the tabs? what kind of props? whats the condition of your bonding straps. these questions are a good start.

It is on a trailer, just painted, Anodes are good but I will replace them, SS props, What are bonding straps?

make sure you get the correct anodes for your application. bonding straps are all the little wires connecting the separate pieces together to create the same potential. how old are your engines? how long is it usually in the water?
