HI-AMP FMD

Postby Phantom5 » Tue Feb 12, 2019 10:09 am

On the bottom back of my transom is this what appears to be a lead bar approximately 12" x 3" with HI-AMP FMD and Do Not Paint, see picture. Boat is a 1980 Panther. Research as to what it is or does for an airboat, I came up dry.. It has something to do with Federated Metals Corporation. Then I got to several books by a bunch of Russian, Middle Easterners and... on books they wrote on Graphene Science of Electrical optical properties aND PHOTOVOLFAIL CELLS and SUPERCAPACITORS.

Ok, so this is supposed to interact with water or salt water for some sort of electrical balance??????

What say ye??????

sacrificial anod-- It corrodes instead of your hull.

fjdrill, nice catch, so don't paint, leave alone and the hull will last another 39 years.

Anodmine

A green, OEM-compliant, surface-active chemistry that protects all virgin metallurgies with a barrier film, thus mitigating corrosion.

Yep; similar is pretty much standard, and well known by anyone who owns an outboard powered boat.

It's a sacrificial anode.helps prevent electrolysis on your hull.For boats that normally stay in the water. A big tour boat is the only airboat that I would think that ever needs one (Stays in water).Any boat that touches salt water should have one for sure. Ive probably changed a 1000 of them things on outboards and just as many busted bolts.

This is on a 1980 Panther 15x7 and the hull inside and outside is very good for 39 years. The anode has very little pitting and the boat will probably spend the rest of it's life on fresh water.

There’re three different types of anodes that I know of; made for freshwater, saltwater, and brackish water. If your boat is left in freshwater, an anode made for use in saltwater won’t be as effective as one made for use in freshwater, and vice-versa.

The sacrificial anodes are made to protect outboard motors, props and hulls from the effects of electrolysis, which occurs in any type of water, not just saltwater. On an airboat, a metal hull is what will require protection if left in the water for extended time periods.

Rick, it's 39 years old and doesn't show any pitting or corrosion on the hull. The anode has sand size pitting over the entire unit, but still looks useable. The hull the best I can tell was in the water up until 1991 in South Texas. Guy had all paperwork for many years including Tx Parks and Wildlife 1991 sticker not put on. Took the old "white" brittle poly off and had Lone Star Boats in Baytown put new 3/8 poly on and have been "Frankenstein" parts with SBC DD. 90% finished with wiring console, bolt seats down, and last put the prop and rudders on.
