[C38] Heat Exchanger

[Charles]

I finally took apart my old exchanger yesterday.  Mine had an 
inspection/clean out port on the end, but the unit is positioned in the 
engine compartment so that regular maintenance is never going to 
happen.  I was surprised to discover the cooling tubes were clean.   
What I did find was Zebra Mussel shells blocking the intake chamber.  
These beasties are an ever increasing problem in the Great Lakes. 
By the way, I do have a screen on my water intake.  I can only surmise 
these mussels actually grew in my cooling system as the shells I found 
were much larger than the screen....

While I am happy to have a larger exchanger, I think in retrospect I 
might have stuck with the old exchanger (cleaned out of course) while 
sailing in cooler waters.

I also have to figure out how to deal with this issue as it appears it 
will be a re-occurring problem.
