I have been reading on this forum some horror stories about pitting on tubes. After much research I found out that the best defense is to make sure the anodes are installed correctly and that there is plenty of material on anodes. I do not have my pontoon yet but I did go over to see it (it is getting bottom paint) I was able to locate anodes on the two side pontoons on the back, one on the transom and one on the yamaha itself but I could not find on the center express tube. Can anyone that has an express package tell me if it is supposed to have one and if so, where?
