I have 3 stripped screw holes I need to repair. One is on the hull itself-One of the screws for the Bimini is stripped out.

well i tried 5200 and it's worthless. I used a two part epoxy that comes in two small tubes, sold at marine stores. I can't think of the name but i 1st filled the hole, then let it dry, and the screw was as secure as day one.

I am fond of WEST SYSTEM Epoxy. Recently they had an application report concerning the use of expoxy to bed screws.
There was a large windmill electrical generating device which used wooden windmill blades (about 25-feet long). The blades were secured to the hub using bolts that were bedded with epoxy.
A high wind condition was forecast, which usually meant the blades were feathered and secured to prevent rotation. Unfortunately, the system failed to work properly and the blades went into a free-wheeling situation. As the wind velocity increased, the blades began to rotate faster and faster, with the blade tips soon going so fast they were almost supersonic. As the wind built to very high speeds (60 + MPH), the blades broke off the hub.
When the blades were recovered and examined, it was found that the they broke a few inches above the hub joint. All the bolts bedded in epoxy were still intact, but the material strength of the wood had been exceeded and it had broken away a few inches farther out on the blade.
After I read this I never had any worries about bedding some screws with WEST SYSTEM Epoxy.
