Hi every one, I am new to the forum and will jump right in with my project. Hopefully you guys can help me steer clear of some of the disasters I am already encountering. I have lurked here a couple of times, so now I am a member and look forward to some good tips and pointers, here goes...
Okay, I have used pressure treated lumber on my jon boat not thinking anything of it and later was warned that it would corrode the aluminum. What? I don’t believe it. Then I thought about it a little and I know that copper is the main ingredient in the treatment to prevent fungus (rot) and I though maybe it would. I love PT wood and have used it with great successes in rebuilding my fiberglass boat. So it only seemed natural to use it in my tin boat. Well I had already used it before I was warned by those that had bad experiences. I questioned the danger and I was WRONG!
I walked out and started looking over the transom of my boat. I had attached a red neck jack plate, a piece of 2x10 pt to mount the motor on to raise it up mainly. I didn’t see any corrosion around it but I did notice some spots. See picture below.
What the heck? This is a hole corroded through the metal. Granted the metal is only 1/8” thick but still… This is in the area where the transom is reinforced with wood from the factory. So I pulled off my red neck jack plate and it looks like this…
Okay, this isn’t good I am going to go ahead and tear into this thing and see what I have to do to correct this problem. The transom is bolted, riveted and welded together for crying out loud.
After looking it over I decide the only way to do this is from the top so I need to cut the weld…
Piece of cake, was easier than I thought using the skill saw and carefully working it backwards…
Oh yea, some pop rivets too…
The cap is off, yep, PT plywood…
So here is the inside aluminum cover piece…
The wood is in great shape, yea! But, I am going to throw it out now!
