My plan is to replace the existing mixing elbow with a dry stack.
Basically I'll cut off the big round can and replace it with a 10"
high stainless tube U that will have the raw water entering 1/2 down
the side that connects to the muffler. I'll wrap the whole thing in
insulation to reduce the burn potential and heat.

Does this sound like a reasonable solution to this problem?

Perhaps, but take note of Bruce's comments.

What you describe is not truly a dry stack but more closely resembles
a "riser" in power boat language. A true dry stack has no water entry
at all and usually exits vertically through the deck like a lobster
boat. Many commercial fisherman and some long range trawlers use dry
stacks and keel coolers to totally eliminate raw water cooling and
exhaust issues.

Thanks for the nomenclature edification. I'm certainly not versed in this.
Regardless of what you call it, is this a reasonable solution? Based upon
the previous response, it sounds OK.
