I'll more than second that. Since this is a raw water line and
operated at elevated temperaturs due to being in a cooling circut,
it absolutely should not be brass. Even though it won't sink the
boat if it breaks, water rising in the bilge could be a dangerous
distraction in a difficult situation. The breakage would also be
accompanied by exhaust leaking into the interior of the boat. You
won't be able to keep a close enough eye on the interior of the
fitting where the problems will be.

Even if this is just a seldom used overflow that seldom sees salt
water, it's still exposed to exhaust gas on the other engine cooling
water.

This is the place to invest in bronze. Brass should only be used in
F.W. and fuel lines.

Well, you'll all be thrilled and comforted :{)) that today I bought
another nylon fitting, as there were no bronze or Marelon fittings
available. Next on the boat chores list is to replace the entire hose
to which the leaky fitting fed, as it's getting old, at the same time
as I replace the fitting. No pressure on it, but I have plenty of
fuel hose, which is the same size, and as I'll route it so as to have
no side pressure on it (as was the case in the broken fitting), I
expect that will last the life of the boat as we own it, since I
speculate what was there was original :{))

Meanwhile, I spent two hours on the silty bottom of the Frederica
River today, after spending about 5 hours in the other Angel's boat
doing hoses, rescuing an anchor and setting up a mooring, from the
first Angel's couple-year ago loss by fouling on a huge lead cylinder
with 6 INCH chain on it. Every bit of it by feel, as there was ZERO
vis, even only ~10' down. More boat work in the first one tomorrow,
and then I'll deal with my own boat's 1-2-3's (small daily chores)...
