I have an original Mercathode system from 1987 with the two little round sensors mounted on the stern of the hull.
im still getting a lot of corrosion on the anodes. I’d like to augment with a second system of the type that mounts to the bottom of the gimbal housing in place of an anode.
i understand there are 3 different versions of the system. One with a black box, blue box and orange or red box
my old system has s black box.
i boat in the upper cheasapeake bay.
boat is wetslipped in a marina
i found a good deal on s blue box system... is this ok to install or do I need to find a black box system?
thoughts?
thanks
So what’s the solution?
disconnect the existing and install? A new mercathode? Something else?
Why yes it is��
ive got two down-on-their-luck livaboards within 50 feet, on vessels that haven’t left the dock or even had functional engines in years
will a galvanic isolator help?
Their purpose is to minimize any corrosive current that flow thru the Shorepower's Ground line (the GREEN Lead)....if shorepower isn't used, then one isn't needed.
It may be worth the investment to have one of the local marine electricians visit the boat and make some measurements - that way you will know what's going on so you can correct the issue(s) once and for all.....
