Tom,
Maybe stating the obvious, but I would try drilling a test hole in a piece of
scrap plywood, to test out getting a snug fit. It's not easy to change the size
of the hole once drilled :-)

Using tape and starting in reverse to drill a neat hole through gel coat is
good advice.
Depending on where you drill, you might get balsa core, especially above the
waterline (not sure if the 35 has a cored hull)
I don't think silicone has any place on a boat. I'd use Sikaflex. (I'm not keen
on butyl either - my deck to hull joint is butyl and it drips everywhere!)
Why a 1 1/4" hole for a 1 1/8" fitting?

3M 4200 will work, but if the fitting is plastic, chances are you will be
replacing it again someday. 4200 is not as difficult as 5200, but neither is
easy to remove. Above the waterline through hulls are the only place that I use
silicone. Polysulfide (Life Caulk) would probably work, but there is a caution
about its use with plastics, and I don't know why. All of the plastic tank vent
through hulls, the shower through hull, and the electric bilge through hulls
needed replacement on my C&C36. Southern sunshine!

Hi listers,
Thanks, everyone, for your advice on the solar charging system and ACR.
Onto the next project!
I'm going to be drilling a hole in the hull to install a
well-above-the-waterline thruhull for a bilge pump discharge hose. The
thruhull is 1 1/8" inch, so I'm going to use a 1 1/4" hole saw drill bit.
I'm going to seal it with 3m 4200. Does this plan make sense? Are there any
surprises to expect?
Thanks,
Tom
