I said "appear" to be below the waterline because the boat's not in the
water, isn't going in the water anytime soon, and I've never actually
seen one of these in the water :) All four thru-hulls are under the
transom counter and below the boot stripe as well as below the waterline
as defined by the existing bottom paint, so I have to assume they are
submerged with the boat floating level. Given their location in the
bowels of the stern lazarettes, I know accessing them is a pain but I'm
paranoid enough that I'd close them when I'm leaving the boat on her
mooring and not returning for a span of days at a time. On second
though, I'd have to leave the two small ones open because those are
scuppers, so no sense in valves on them at all.
Here's a pic of the two port side thru hulls, big one is the exhaust. 2 more
on the stbd side in the same configuration.

Regarding seacocks on transom thruhulls - what do you mean by "they appear to
be below the waterline"? Either they are or they aren't, and it should be
pretty easy to determine this (are they submerged or not when the boat is at
the dock?). I'm not familiar with the 34+ but looking at some pictures on
Google Images it looks like the transom is similar to the LF38, which would
mean the exhaust thruhull and others are above waterline, but can be submerged
when you're pitching a lot in a wavy sea state.
The recommendation for seacocks is have them on every thruhull that is below
the heeled waterline. Whether you consider transom thruhulls that are 6-12"
above waterline as being below the heeled waterline is probably debateable.
What I've heard is most people don't bother with them (especially since access
to them is usually a giant pain, so the seacock would rarely be closed) -
*unless* you plan to go offshore a bunch. Although even offshore if a hose
pulled off you could probably just stick a wooden plug in (or potato or any of
the other thruhull plugging devices).
So it's a matter of personal preference / your own paranoia level. I'm pretty
paranoid about below waterline thruhulls but for the transom ones I've decided
there are bigger risks to fry first.
