[C320-list] exhaust elbow question

[Rod Boer]

Allan,

I am also planning to replace the elbow this winter but I am also going to
replace the motor mounts.

Koen - There are 2 concerns with the exhaust elbow.  The first is that it
clogs over time and will impact engine performance.  The second is that it
eventually gets pinhole leaks.  Both happened on my previous boat.  Trust me
when I say that you don't even want to think about the mess you will have if
the elbow gets a pinhole leak.  The engine compartment fills with black soot
that never completely goes away no matter how much you clean, clean, clean,
and clean some more.

I intend to replace my elbow prophylactically over the winter at about 500
hours, change the hose to the aqua lift muffler, add a hump hose at the
muffler, and pull the muffler, send it back to Catalina, and have a
duplicate muffler made to sit on a shelf until when I need it.  Again, you
don't even want to think about the mess if these parts fail.

I seem to remember someone mentioning that the exhaust elbows on C320's get
clogged and are recommended to be replaced every so often..
My local mechanic, who will do the very first service on our boat soon (so
we do not have experience either with him or with the engine
service in general), recommends we order the elbow and gasket from Perkins
(I believe tadiesel sells them?) in advance to save time.

Is this a good suggestion? We have purchased the boat used 2 seasons ago, so
I have no idea what the history of this part is.

Thanks for any suggestions,

-Koen
