Thanks for everyone's advise on this topic. I did remove the small elbow
and it was clogged. Once unclogged (and a coathanger jigged around
inside the exhaust manifold hole) and reassembled water flow is returned
and she is "gushing". It even seems to rev up higher than than previously.

I drilled out the buildup in the small right-angle fitting going into the
elbow, which gave me another year. I was surprised it took a drill to clean
it, but it wasn't going anywhere with a gentle touch. I replaced the mixing
elbow the next year. Now I just figure it's something that needs replacin
Kinda what I meant. I usually pull the mix elbow so I can make sure it's clean.
If you can remove the hose and its small elbow, clean it and clean its entrance
into the mix elbow, that works.
The couple of Yanmars I work on for this issue have easily accessed mix elbows.
In fact, I think it's
But his issue isn't with exhaust getting through the elbow, the issue is
with water getting into it - so my money is on the little right angle
elbow into the mixing elbow.
I've had the gasket for a year for removing the mixing elbow to check
it, but it never makes it to the top of the list.

But If it's the original elbow, I suggest replacing it. It's not pretty
when the side falls out of it due to corrosion and your boat slowly fills with
exhaust gas and dirty water.

Common issue with Yanmars. Soot builds up in the mix elbow. Pull the mix elbow
and clean it. Should be 4 nuts.

Hi Dave
I had this problem when we bought SP, little or no water was making it
through, and it turned out to be the right angle elbow was clogged. I
cleaned it out and she's run fine ever since.
I took the right angle elbow off of the mixing elbow, it just unscrews.

Secret Plan
It's almost certainly the mixer elbow.
I replaced it on my 2GM20F a couple of months ago. Take the manifold and the
elbow off as one. (You won't be able to separate them anyway.) There are
four bolts where the manifold connects to the engine.
