So many boats have dubious installations at the thru hull. My /Vega
had a 1 1/4" bronze gate valve screwed to a nylon thru hull.
Dissimilar materials is one concern, but not using an actual seacock
is worse, particulatly in this 32 year old installation. (I
invisioned the brittle plastic thru-hull snapping off below the
valve.)
I suggest taking a look at an actual through bolted seacock
installation. Try:

A new sailor may not be able to tell the difference, but this kind of
thing really impresses a marine surveyor, and could save lives.
