I attached wood to my bench with #14 x 2" self-tapping screws. I put one in each corner, then another about 8 inches apart. I then attached my seat mount with the same screws. Stainless screws would be best for corrosion, but I've used zinc plated and they haven't started rusting yet on my other jon which was done 3 years ago.

Check out my boat in the Boat Modification forum titled Alumacraft 1236 Makeover

you could use some liguid nails or 3m 5200 sealent and screw it it wont come loose but if you have to take it back off you would have alot of cleaning up
The fishing was good,it was the catching that was bad

it doesn't matter how thick the metal is.. i mean, mine is like 1/16" thick if that.

If you drill 1" holes, how are you going to get under the bench to get it tightened? Unless you use those wall anchor type nuts/bolts that you use for sheetrock that expand as they are tightened.

A pic of what you are working with would help.

i think he means he is going to drill holes in the side of the bench to tighten the nuts

Before attaching the wood, be sure to paint it with several coats of paint. After that, I suggest using the Liquid Nails as already suggested, then the bolts or screws. Wal Mart sells an acrylic enamel for a little over 16 dollars. I just added plywood flooring and coated it with three coats....before carpeting....especially the edges of the wood and particularly in your case, at least three coats on the end grain. Do no use stainless steel bolts or screws. It sets up a galvanic response and will deteriorate the aluminum. Also, marine plywood will affect aluminum...as well as treated wood. Hope this helps...good fishing, Mac

If you decide to use liquid nails.......a tip or two...

Use the industrial or heavy duty.

When applying it to the board.....use a serpentine looping patttern......this leaves gaps for air to escape....picture a snake laying on the board, his head at the upper right corner and his tail, after looping back and forth, his tail at the lower left corner. The snake at no point touches himself, but overall is a long snake looping back and forth along the way. Hope this isn't an inslult to anyone's intelligence, but the open loops are the way to go.

Good Fishing, Mac

I don't know about mounting wood to the seat but I've mounted rod holders and a sonar bracket to my seats using the correct drill and 8-32 tapped threads with 8-32 stainless machine screws. The seat metal on mine is rather thin but these screws appear to hold pretty well.

Hey i think you were refering to regular steel mac. Stainless steel is fine for a aluminum boat it wont cause any problems. You are correct in that most pressure treated wood will be harmfull to a boat but most marine grade wood is fine. Marine grade wood does not mean it is treated it has more plys to it then regular wood wich makes its denser and therefore you can use a thinner peice of wood. It also lasts longer since it is a better quality of wood. Most people on this site though just use furniture grade ply wood and coat it with something like thomsons watersealer.
Good Luck

I would use toggle bolts with a dollop of silicone sealant on the toggle. That way if you have to remove the wood, the toggle will be still there when you replace the wood. Silicone won't be needed if there is unrestricted access to the under side. If you have complete access I would use 1/4" x 20 Flat head screws.
