Need Some Help About Galvanic Corrosion!
Can I Use A Mercathode System On A Aluminum Pontoon Boat To Keep The Pontoons From Corroding? I Keep The Boat At The Jersey Shore In A Slip For The Summer.the Bottom Has Been Painted With Aluminum Bottom Paint & Primer.plus I Put Out Two Extra Zincs One Foward And One Aft But I Still Had A Large Amount Of Corrosion. Help!!

I'm sure no expert but::Be sure everything is bonded together as one.Pontoons,frame,deck,motor.Be sure there is no stray voltage
from your electrics including shore power.Be sure your zinks are installed properly and in excellent shape.If there is a problem with the marina power or a neighboring boat it could be your problem as well.
