Re: Screwing down vinyl deck and pouring foam

About posting the pics, click on the reply with quote button on my post with your pic in it and you will be able to see what code I copied from photobucket. You can also see how I posted it in a line by itself, don't try to post the pic code in a sentence it needs to stand alone. If you still have problems, just upload your pics to photobucket and I can post them for you until you get the hang of it.

Take some more pics of your boat when you get all the wood and foam removed so we can see exactly what you have to work with.

Electrical work isn't my forte, but you can get some good help in the electrical forum on this site right here:
Electrical, Electronics, Audio and Trolling Motors

About pouring your foam:

It's much better to pour the foam before the decking goes down, you can get a complete and void free foam filled hull that will displace any water that tries to enter and actually seal your hull in case of a breach. This can be achieved by using a sheet of cheap OSB plywood wrapped in 6 mil plastic sheeting , I'll expand on this further if you're interested.

Sealing your decking:

This is very important and the better job you do of it the longer your decking and vinyl job will last. I strongly recommend using 2 part marine grade epoxy resin for this. USComposites (google it) has a 635 thin epoxy resin that works very well for this. Most people use the 3:1 medium hardener, but if you're working in cooler temperatures you may want to go with the 4:1 fast hardener which isn't really that fast in cooler temps.


Have you checked your transom wood for rot? Now is the best time to do this since you already have the boat taken apart and it'll be much easier to do now than waiting until later and having to take your boat apart again. Some folks go ahead and change it out whether it looks like it needs it of not just for the peace of mind and so everything will be new on the boat when it's finished.

did you ever check out the vinyl job I did to my boat I posted the link to back in post #7 of this thread?

Re: Screwing down vinyl deck and pouring foam

Just put some new pictures of boat to Photo bucket, questions for pictures are 1) first picture is of boat cleaned out, foam was in most of bottom but there is no drainage?? Second and last picture shows the solid framing of the back of boat, can I add drainage or not? 2) You talked of replacing transom, when and if I do it doesn't look like that big if a deal, am I missing something?(is that the transom) 3) the other pic. is of the inside bottom of the boat, there is some pitting I am thinking came from the electrical panel not being grounded(not my doing), can I put something on this to reinforce? thanks B.H.

Re: Screwing down vinyl deck and pouring foam

trying again to get a picture posted from photobucket, if this works, it's of the back of the boat, do I need to replace it? it's only about 5/8 inch thick and is just screwed to the back of the boat?

^^^^ This is the motor pad on the outside of your transom ^^^^
Yes, it needs to be replaced. It should be sealed on both sides and all the edges and then painted with at least 2 coats of good paint. There should be more plywood on the inside of the transom where the braces are, that's what I want to see a pic of.

We need to see a pic of the inside of your boat looking from front to back, like this one... but looking in the other direction.



^^^ This pitting/corrosion is fairly common with aluminum boats that have been left exposed to the elements. The fix is to clean it up with a stainless steel wire cup brush in a grinder or drill and then skim it over with a marine epoxy for metal like Loc-tite Marine Epoxy of JB Weld Marine.

In Photobucket, You should see the "IMG" code displayed in a window. If you right click on it, a window will open and you can select Copy. You can then return to iBoats and Paste this code into your iBoats post and your picture will be displayed "full size" in your post.

halvi76's Library | Photobucket Well I found the link and it copied to the lift but it's not in blue like I have seen others, maybe it will when I post it. If it doesn't work F>Y>I> I did take a couple of pictures and the entire back of the boat is covered with aluminum, I can't see anything wrong with it??? B.H. ( here goes )

Re: Screwing down vinyl deck and pouring foam

Well, actually, the IMG code is preffered. If you hover over the pic and see the flower in the upper right corner and click on get links and then click the IMG codes window it will say copied and then you can return to your iboats post and paste the code into your post and get this..

Re: Screwing down vinyl deck and pouring foam

Here is a picture of the back, inside of the boat, I don't see how anything would get in there but take a look and let me know. Getting into there would not be easy!! Thanks B.H.

Re: Screwing down vinyl deck and pouring foam

Your transom plywood is behind the aluminum sheeting in this area:


It sits on the "Z" angle (red arrows):


By the looks of the dimpled in sheeting in the orange circles I'd say your plywood is probably weak/rotten and should be replaced.

I'm pretty sure that the screws for the motor pad on the outside of the transom have let water into your transom core encased in aluminum, and since it is encased it has never had a chance to dry out and just keeps letting more and more water in every time the boat is in the water or left out in the rain.

Re: Screwing down vinyl deck and pouring foam

If I take out those rivets, what do I replace them with? I am not really equipped or knowledgeable enough to open that up? Or am I...

Re: Screwing down vinyl deck and pouring foam

Those rivets can be replaced with stainless steel hardware... bolts, nuts, and sheet metal screws. You may also be able to use some aluminum closed end blind rivets in some places, but most people just use the stainless hardware.

Re: Screwing down vinyl deck and pouring foam

I checked the back of the boat and the dimples you see is from me tightening down the bolts I run through to keep "honest people" from stealing my motor. From the side I can feel the plywood and I dug in the bolt holes, it did not seam to be rotted???
