A couple of the snaps for the pop top enclosure have stipped out. There does not seem to be any damage besides the enlarged screw holes. What is the best method to repair the holes so the snaps can be screwed back in? I have a 1988 Catalina 22.

Same thing happened to me. I drilled out the hole to clean it up and will be putting that 2 part white putty stuff in the hole (what was the name of that stuff - Marine tex I believe). After it hardens, I will drill a new starter hole for the threaded snap. Should work, I'll let you know.

I need to do the same with my pop-top lift brackets.

For a blind location, both in metal and composite structures, I would consider a rivnut. You end up replacing the sheet metal-type screw with a machine screw.

There are a few installation tool options, all of which seem to work fine. Though not always the best in close quarters, I prefer the feel of hand squeezers:

Here’s a wrench-driven style from Wicks Aircraft supply – they work well too and are better in close quarters:

This is one of those tools that you can do without for a long time, but will find uses for one you have one. :-)

Good luck!

I am having a screw hole problem (story of my life!) -- I have a bunch of screws that are loose but I can not seem to remove them. I tried putting some tension on the screw head and then unscrewing but they did not unscrew. Thoughs?

question: I have a few holes on the cockpit side of the transon where the PO seemed to have had some deck hardware attached and is no longer there leaving the srew holes, my question is, how do I fill the holes and does that "Marine Tech" stuff work for a job like this?

See if you can use a chisel or putty knife to get under the head of the screw. Pry it up as you unscrew it.

Marine tek works fine for filling holes. It drys fast and sands easy but it will not match the white of your hull. If you are rearlly particular you can sand it flat and then spray white gel coat over the top to match the rest of the hull--but this is an advanced technique.

What I do for holes in the rear of the cockpit, or any where that I can get to the back of the fiber glass wall, is to add a patch of glass, cloth, or wood soaked in Epoxy on the back of the hole/s. Then you can fill and finish or put screws into the new wall. I have been wetted to using WEST (Wood Epoxy Saturation Technique) Systems epoxy, as oppposed to polyester resin, or Bondo, but they might work as well. I guess I believe in epoxy since using it on my 35' cold molded plywood boat for 15 years.

Heres one for you listers, for your information Northern tool ( NorthernTool.com ) just today came out with a sale catalog. On pg.4 they are offering a kit for installing rivnuts for $10.00. It comes with 40 threaded aluminum rivets in the sizes 6-32, 8-32, 10-24, and 1/4-20. Might just be useful.

I'll echo Al G's comments but add that West Marine carries a tinting product that can turn the usual yellowish epoxy a nice white color. My C-22, Time Out, is literally covered w/screw holes from projects by POs. I'm filling them in sections and am very happy with the results.
