Thru hull windows

[FL.flatback]

The frames will be 5200 to the outside of hull. Then the plexiglass will be laid in the hull cutouts on the flange of the frame with the adhesive/sealant. The inside seam will then be fiberglass like it was originally. The bolts will then go from the bottom. Through the  frame,plexiglass and fiberglass that was used to seal the inner seam. HH uses a frame with 5200 on the inside and outside to sandwich the hull/plexiglass. Im guessing the bolts tie the whole thing together. Minimizing the chance of the plexiglass coming in through the hull.

I see what your saying about the Sika not showing below waterline usage. I will check back with Merritt before using it. This is something I'd like to do once.and not worry about it. The boat is coming along great. I'm ready to go fishing.

Does the outside frame stay in place? Do you gelcoat over it? I'm getting a little lost on this part.

[FL.flatback]

Yes the frame stays on the outside. They are just under 1/8" thick. So they don't hang below the surface much. I don't know if gel coat will stick to them. If not I guess paint to match.

I've been thinking about this and wonder if you have to have the frame after the glue dries. Once the window is bonded I would think it is bonded.
I was reading a thread on Bateau2.com and this guy used Plexus MA 425 http://www.jamestowndistributors.com/userportal/show_product.do?pid=4885

Here is the thread where he is using it to glue down his deck on his boat. http://forums.bateau2.com/viewtopic.php?f=12&t=28463&start=300#p322845

I wonder if it can be used underwater?

Hi FL, here is a shot of what I'm starting with...

 Hey merkin, yours don't look so bad from the bottom. Mine were iffy on the inside. It looked like someone tried to maybe repair a leak with something like marine tex. Plus they were pretty hazy. I'm feeling a lot better with my new re-install. I just got done gluing in the frames today. When i get the windows in I will definitely post some pic's. I'm guessing next weekend the 5200 should be cured enough to remove the clamps. Does your's leak? You gonna try'n replace them or polish?

[RickK]

What glue did you end up using?  Are you leaving the frame on the outside?

[merkin222]

No leak issue on these, and they don't appear to have gotten the "aftermarket" treatment either. I'm planning to polish and see what I get. I'm told the material may be yellowed and or scratched bad enough to negate the purpose, like the hazy look you described, but they're dirty enough that it's a little early to tell. - Really looking forward to seeing yours once finished, FL. No doubt it'll be great to have nice clear "windows" on the life below. - You have any concern/plan for the glare issue? I tend to think a dodger might be enough to block direct sun so you can see well through the panels, but wonder what you plan to do.
