Yanmar 2QM15 muffler, exhaust hose?
 

Looks like I'm going to replace the exhaust hose and muffler for my raw
water Yanmar. Anyone have good sources for these?

I just replaced my last spring.
I do not know where you live and can only tell you what I have done.
First you have to check at you diesel engine outlet what is your exact OD of
the hose.
In your case I believe it's 1 3/4" ID. In some case some builders have
installed a reducer close to the exhaust elbow from 1 3/4" to 1 1/2 ID to
the water box exhaust then to the outlet pipe on the transom. In other
cases they use 1 3/4" OD all over.
What I bought is the Marine Certified exhaust hose. It is traced with a
blue line and the specifications are printed on the hose. If it is not
Marine Certified exhaust hose do not use it.
As for the price per foot you can start on line with West Marine site. It
is priced at about $7.00 to $8.00 USD per foot. plus shipping. Hamilton
Marine also has a good supply. What I did is I bought the same thing at
Bridgeport Marine,(Canada) a commercial fishermen supply store, for $3.50
CAD per linear foot.
As for the muffler box, If you're in the States, you might as well check
with West Marine or Hamilton Marine if you are in Canada check with HMP.
