I did something similar, only I single pointed it in aluminum. Cut
it
upside down to have the bit leaving the hole. I had to modify the
acme profile some to get the handle to spin in. It was for an
adapter
to allow me to get the engine flush bracket onto my outboard while
hanging over the transom (it was in a marina on a lift at the time).

Why do you want to do it from inside the boat? On friends' boats,
they/we always put the flusher on the outboard (or I/O) from the
ground, then turned the water on, then started the engine for a
minute.

There was no ground. The boat went from lift into the water, then
upon return, straight back onto the lift hanging over the water.

Crikey, how did I miss that "marina" phrase? sigh Mea culpa.
