They were bought by Helmsman including the name. The tooling has been revised as well as outright tossed out with new tooling made. Camano is no longer used and it is just called the Helmsman 31.

It is the exhaust from the gas/ water separator. The valve lower down is for the water.
The other valves you see came Fisheries Supply in Seattle and were
shipped over to the factory.

What's the thu hull with the big hose with no valve? Or am I looking at that pic wrong? Oh wait, maybe that's an exhaust hose?
And I wonder if there is a thread mismatch on those thru hulls with the ball valves screwed on.

Should there be a seacock there?
I really know nothing about boat construction, but looking at mine...

Never hurts to re-check so I just examined the diagrams again. This is how the Dutch design things and they have to adhere to mandatory standards:

Wow, what a NICE vessel. Seems like there's some new smaller trawlers that are very well laid out with some super features.
Good choice.

That's what I was wondering-- no seacock on that thru-hull, but didn't know about that separator it goes to. Maybe a check valve there or something?
Is it common to have exhaust exiting under water like that?

In the installation instructions photo there is a valve shown in the below waterline water exit after exhaust/water separator.
It appears that the hose in your installation has no valve.
If you were to pull that hose off of that thruhull what would happen?
If as I suspect, sea water would enter the boat then you have a fairly dangerous installation and didn't conform to the drawing shown.
Isn't that new thruhull below waterline? Aren't the thruhulls next to it intakes for the generator? Am I missing something?

There are two outlets from the separator. One above water line for the gas fumes , the second is below the water line for the water - the two have been separated. The below waterline valve is just barely below water.

Ok,
Let's do it this way. Is the hose that I've marked with a yellow arrow "just barely" below waterline?

No it is above waterline. That is the gas fumes exhaust.

Interesting!

I'm very confused...
No biggie,

I was using the iPhone to take the picture so it isn't the best picture. There are three hoses attached to that separator. The hose connected to the center of the separator is from the water lock device (which looks almost exactly the same as the separator). Then there are two other hoses exiting at the top of the separator: 1 for water, 2 for gas fumes.
The water lock device is connected to the genset directly and prevents back flow. It is installed slightly below the genset. Then the separator is connected to this water lock minimum 24" above water line. The hose runs 24" from the water lock to the separator .

Anyone concerned about NPT (tapered thread) ball valves on straight thread thru-hulls?

Roger that! I think I've got it now. 
Those thruhulls are in the vertical side of the hull, not on the floor of the ER. The exhaust (without the seacock) is the highest one and it's above the waterline.

That is correct. The lowest valve (barely showing in the picture -
is the ball valve.

Ahhh. I get it now! From that pic it looked like they were mounted on the bottom of the hull. I suppose the light shining through the deck should have been my clue.
Sorry for the confusion.

This is the water lock that is mounted low against to bottom of the hull and connected in-line to the separator:

This is 1 minute video on my personal YouTube channel of the gas/water separator just installed to the Whisper Power 3.5 MSC. You can see the water discharging below the gas outlet. Recorded with an iPhone starting outside, so the sound will be subjective, but rather quiet IMO.
