Aluminum hull corrosion pin hole repair. Thread starter nickle and dime Start how to repair holes in aluminum boat Jun 13, Joined May 30, Messages 8. I have a 16' crestliner Imperial that i picked up in lakeside oregon. It needs work as it has been sitting on a rusty ol trailer for years.
This last weekend i removed the ply wood iin and all the foam planks and found about 3" of dirt and muck. I cleaned up the muck and took a wire wheel to the inside of the hull. I found some pin holes in about three different spots. I like the idea of using the marine tex and Gluvit. I'm pretty new to this aluminum repair stuff what is marine Tex?

Scuff it up really good and throw some JB on it and you are done, I repaired a huge crack in a lower unit with it and it held without leaking for the 3 years I owned and I am sure it is still fine.

Re: Aluminum hull pinhole Re: Aluminum hull pinhole That is pretty how to use transformers in tekkit so I would use the Jb Weld, Gluvit is for small pin holes and you have a hole, scuff it up really good way around the repair and use the JB, you may want to put some tape on the inside of the boat so it doesn't dribble through, should fix you right up.

May 01, · How to replace rivets and repair holes in an aluminum boat. Apr 20, · So I got my first boat, a aluminium one, and now after one season, its leaking. I tore up the floor to have a look and there is deep pitting and one smal hole in the “grooves” at the bottom of the hull. The brown hole in the middle left of the picture is about 2 mm.

Aluminum boats have several advantages over wood and fiberglass. They have lighter gross weights, which make them highly maneuverable, faster and more economical to run. Wood rot, typical in wooden hulled boats, does not affect aluminum, nor does aluminum shatter upon impact like fiberglass.
This makes aluminum boats easier to repair than other designs. Unfortunately, all boats suffer impact damage, collision or hard-grounding that can lead to leaks and cracked seams.
Fortunately, special brazen rods have been designed specifically to patch and fill in holes on damaged aluminum boats, allowing boat owners to perform self repairs. Remove the boat from the water and take it to a sheltered garage or port. Place three sawhorses in a triangular configuration on a level surface. Have an assistant help you lift the boat up and balance it hull side up on the three points formed by the saw horses.
Clean the damaged area on the aluminum with some acetone and rags, removing algae, mud and all chemical water stains. Wear a particle mask and gloves for protection. Place the boat in such a position as to face the hole or crack at its highest upward position. Have your assistant hold the hand anvil while you wield the hammer. If the aluminum has suffered a collision impact that has dented the metal inward, you will need to pound the dent out from inside the hull with a body hammer, while your assistant provides a backstop with the hand anvil.
Straighten the profile of the hull as best you can by repeated tapping and straightening -- you need the stretched aluminum to conform closely to its original shape. Determine the size of the crack or hole and whether you need to back it with some scrap strips of aluminum. If so, dab a small amount of epoxy on a thin strip of aluminum and glue the piece to the underside of the boat directly over the crack. This will provide a trough for the brazen rod material to settle in.
Use a drill motor and a grinding cone bit to grind a V-shaped channel in the crack. In the case of a hole puncture, bevel the inside of the hole with the cone bit, grinding only enough away to provide more surface area for the brazen weld to adhere to. Sand the surface area of the crack with grit sandpaper, overlapping the crack area on all sides.
Use a propane torch to heat up the crack area thoroughly. Scrape a wire brush over the area, using crosshatch strokes to rough up the aluminum surface. Hold steady heat on the crack while you apply a tip of HTS brazen rod over the crack sides. Let the brazen melt and flow into the crack or hole, filling it up. Melt the brazen rod onto the damaged area to cover and overlap it completely. While it cools, scrape the wire brush over it to remove small slag and residue.
Use a flat file to grind away any excess brazen material that protrudes up past the aluminum panel surface. You want a nice even profile, without removing the thickest part of the brazen weld. Remove the scrap aluminum material from the underside of the hull. For added strength and protection, you and your assistant can flip the boat over and sand the inside part of the crack area.
Run another bead of heated brazen weld over the crack area, and then file it down. Chris Stevenson has been writing since His automotive vocation has spanned more than 35 years and he authored the auto repair manual "Auto Repair Shams and Scams" in Stevenson holds a P.
