John,
Sounds like that installation might not ever leak or fail.
A lot of work though, and perhaps a little overkill, not to criticize the one and done philosophy, in which myself and many certainly believe.
Oversized fender washers on the underside to grab surface area and the standard beveled hole / butyl tape method of mounting deck hardware is how I intend to remount my blade tracks, foregoing the oversized, epoxy-filled 3/4” holes.

Good point to check the locations of the 1/4” holes inside the cabin before drilling. The underside, reinforcing deck gussets sometimes align with the exact location where the track says there needs to be a hole. (Thanks a LOT, Murphey!) Perhaps drill a very small hole (1/16”?) just forward or aft of the gusset from inside the cabin to quickly locate the gussets on the deck, position the tracks and then fill the small hole afterwards? No one likes drilling holes anywhere on a boat but the smallest of easily filled holes might be worth quickly determining the gusset locations on the exterior.
I too am curious about any performance difference you witness with the new track positions.Testing revealed the 17.5” outboard location to be not only faster, but higher as well.
For those of you who are not aware, Galveston Bay’s Fleet 2, based at Houston Yacht Club, races and sails using the blade all the time.
Best regards,
