Hi Graham,

I didn't need to install through-hulls. There were fiberglass tubes
attached to the boat at the top (1 1/4") and bottom (3/4") of the drain.
The reinforced plastic hoses are clamped to those tubes. It would be nice
to replace the top fiberglass tube with a through-hull, but the top part is
part of a curved drain channel (on top of the bridge deck) and the bottom
of it has very limited access. The bottom tube attaches (I believe) to the
CB housing and I'm in no hurry to tackle that project.
