Mounting Bennett Trim Tabs-protecting the transom

[JW-Tex]

Who has used oversize holes filled with thickened epoxy for the tab screws to mount into? Any tips based on your experince? I have used this method for my garboard plug but am not sure it would hold up on the transom with the force exerted on the tabs. I want to avoid water intrusion in my new marine plywood transom. Any input or opinions would be appreciated.

I WOULD NOT USE THICKEN PUTTY ALONE / I WOULD BACK FILL THE HOLES WITH A DOWEL THEN REGLASS OVER THE HOLES AND RE GEL COAT/ TABS PUT A LOT OF STRESS ON THE SCREWS

The best way is to overdrill, but put in a G-10 insert instead of a dowel. You can then tap into the G-10 and it will never be a problem and you do not need to glass over it on the outside.
We buy G10 at McMaster Carr, but a quick web search turned this up G-10 supply

You can get the stuff in sheets, rods, whatever, and it is very tough, holds a thread, and is easy to work with. Great material for quick fabrication. I also use this for engine mounting holes-overdrill and then put in a G10 tube and you end up with a compression tube that will not allow the transom to be compressed by some mechaninc with a big wrench. Just leave it a c.h. long after you glue it in.

I would worry about putting wood dowels in-how is that any different than the plywood you already have?

I figure good old 5200 lasted 25 years so I did it again....
Will probably remove and replace every other year since I keep it on a lift now.
