    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.

    When I looked at it from the top side they were glued brakets like the pump shoe. It would still be a good idea to block them off the more I think about it tho to order to keep corrosion down if your running without tabs for extended periods of time.

    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
