I pulled my 48 in Sept for its winter vacation from the family. then I noticed my trim tabs were not looking too healthy. the spot welds from the L bracked to the running surface had come apart on a few. I checked with formula and they said talk to Bennett. so i did, they said send pics, so I did, After looking at the pics they said "you don't have any zincs on those tabs" I said the boat has a bonding system and everything is linked. Unfortunately the trim tabs are NOT linked and the electrolisys is what caused the welds to come apart. Easy fix with a couple of stainless nuts and bolts, but future reference make sure you put zincs on your tabs before you splash this spring. I think Formula should have put them from the beginning so I would have known they need them but whatever.
