Trim Tab removal... hole blockoff
For those of you who run tabless for speed runs/cruising and with tabs on roughwater/tight turning days this may help....
You can use allen head 6mm X 1.00 setscrews to fill your bolt holes. This way you can easily fill the hole, without putty, cork or other that you would have to dig out.
I am not sure where to get 6mm setscrews so i just purchased 8 setscrews from lowes 1/4 x 28 pitch 1/4 inch long
Using a 1/4 28 tap, i cleaned threads about 1/4 deep and inserted set screws. I wrapped tape around my tap to mark how deep to go. If you remove the setscrews to reinstall your tabs, the stock bolts will screw right in as normal and hold just as tight since they are much longer then the set screws...(see pic of stock bolt through tab with setscrew beside)
From Lowes in hardware..

Why fill those holes? Pretty small and not a resistance issue since water is most likely not even hitting that area at speed. Just curious.

Doesnt water get into hull there? I just figured.. empty hole... put something in it

I have mine sealed and 2 still leaked. They will leak between the hull and the insert . Inside the bolt holes on mine it is solid at the top so it will not leak in the threads. I also filled the back of my hull with water to find the leaks.

some guys are using button head bolts to seal the threads and inserts. With mine these allen heads are sealing the threads. I put light coat of epoxy over the inserts, then use the allen set screws to seal threads. The epoxy stays over the inserts whether i am running tabbed or tab-less
