Re: [Amel Yacht Owners] electrolysis on jib furling gearbox? [1 Attachment]
While you are waiting to install a galvanic isolator, consider buying an additional easy to install (i.e. no haul out required) sacrificial anode like this one or similar: https://www.amazon.com/Martyr-CMGROUPERZ-Alloy-Grouper-Hanging/dp/B001TK98LM
It can be connected to the green/yellow bonding wire at a terminal in the Aft locker and then just hung off the back of the boat. It will give you some additional protection of your underwater metal until you get the issue sorted.
