Morgan Thru-Hull fittings

My Morgan has through hull fittings that are glassed into the hull. Some of these have a screen on the outside, but most are flush with the hull. While I have owned an older boat (1970 Pearson), all the through hulls on that boat were not glassed in and had a flange on the outside of the hull.
Most of the through hull fittings on the Morgan need work- new seacock valves and handles.

Anyone else have this configuration? Have you changed these out?
I thought that I could un-screw the seacock ball valve and simply screw on a replacement, but the fiberglass goes up around the ball valve as well.


Any suggestions? I would prefer to replace the entire thing with a more modern configuration where the thru-hull is a mushroom type (with a flange on the outside) with a backing block inside and a thru-hull flange nut on top of it, and then the ball valve.

Happy Sailing

Morgan thru hulls

Why not keep the thru hull in place and only replace the valve? That's what might be the simplest option.

Thanks

I agree, after closer inspection, it appears that just new handles and cleaning (for most part) is all that is required.

Just finished all my seacocks and throughulls on my 1978 382. The original throughulls were in excellent shape.

I've got a 1981 416 with a non-functioning thru-hull for the aft air conditioning intake. I've never had to deal with thru-hulls before on my 26 ft Chrysler day-sailer, so this is all new to me. What do I need to do to repair the thru-hull, so that it keeps water out when closed? Also, what is the best method for unsticking and lubricating the thru-hulls before the boat goes back in the water?

Thanks in advance,
Lesley

Ball Valves are the ones I am trying to sort out. There are a couple Gate Valves that I need to replace, but the Ball valve type is the one that is broken.
