Just to follow up, the fill & re-drill with thickened epoxy her held great for the last three months, and I think I am good to go (since the original job failed after only about 3 hours under autopilot). Thanks!

I doubt you're weakening it.
I have a Raymarine ST1000 on my P26 and it's been there 6 yrs. (covered w/ tiller cover when not in use. We fashioned a custom made "hump" out of teak to raise the pin to the tillerpilot's height, and drilled a tight hole into which I epoxied the pin.
In 6 yrs. the hump-to-tiller joint (bronze screws plus thickened epoxy joint) is tight and so is the pin.
I could be wrong but think if you fill (use thickened epoxy) & redrill you'll be oK. Mine is coated with Cetol light & clear finish. After 5+ yrs. it is still solid & sound & looks OK.

Advice for repair of tiller pilot->tiller connection
The 'pin' in my tiller where the arm of the Raymarine SmartPilot X-5 connects to the tiller has come loose. It appears the force of the tiller drive on the pin acted like a lever and the force on the pin was more than the Epoxy cold hold. An Epoxy field repair lasted a couple hours, but then failed again because the 'hole' in which the pin fits has become enlarged.
My plan is:
1. Drill out the 1/4" hole to 3/4" or so
2. Wet with unthickened epoxy, then fill with thickened, cure
3. drill back to manufacturer defined size and depth (1/4" hold 1/2" deep)
4. Re-epoxy pin into tiller.
My *worry* is:
Am I weakening my tiller with such a large hole drilled and filled with Epoxy? If that 'plug' should ever pop out its a pretty big hole in the tiller... and I have this bad image of myself in rough seas trying to control the boat with only 16" of tiller left.
...and an additional question:
Whats the best way to protect the epoxy from UV? Do I have to paint it or will it take varnish (like the rest of the tiller)?
