Intake and Outflow Valves

Good morning everyone!

My head intake and outboard hull fittings have no valves. I guess previous owner, believed in luck and his plumbing skills to keep the boat afloat.
Well, its time to get something done about it.
I am know that I need 90 degree ball valves. I was planning on diving under and pushing two Tru Plug cones in the intake and outflow of my hull fittings to prevent water from getting in while I am working out it. However, I am not sure how to glue those ball fittings on. What materials should I use? What precautions to take, etc.

Any help would be appreciated!
Here are photos of the current set up

Seacocks should thread on to the thru hull fittings, not glue on the thru hulls.They may glue on, just never seen it done that way, SCARY to me if done that way IMOH..

I replaced all the thru hulls on our boat by lightly tapping the plugs in like you are talking about doing. The only one that was a problem was the engine intake because it has a screen over it. Just used a piece of plastic sandwich bag over it and open the valve. Suction holds it in place with just a little leakage...

Not exactly recommended, but I was at the yard and could get pulled if necessary,,

Ditto! The backing plate is the only thing glued on.
What kind of a boat are we talking about here. Your attached links do very little to show what you have.
Below is a picture of the system you should have below the waterline.
