Overheating:
After experiencing the same symptoms as listed in this thread. I removed the
old mixing elbow. No surprise, after about 670 hours the elbow is almost
completely clogged with carbon.
I sent a digital picture to Elias at Pacwest Marine.  After a brief phone
conversation with Elias to confirm parts and make the necessary  payment the
parts where shipped.
I just received a new mixing elbow, threaded joint and gasket from Pacwest
Marine (619-222-0475). 
Replacement is an easy process but you will need a large wrench and a sturdy
vise to unscrew the joint.
The threaded joint was in good condition and didn't really need replacing. 
Total cost with shipping = $215.50  subtract $35. If you use your old joint.

Dennis:

Excellent idea. Someone else made a similar suggestion. I'll add that to the
list of things to check. Thank you.

On my 2002 hull 906, it's the battery charger (which does have a fan)  
that's mounted on the port locker bulkhead aft of the reefer box.  The  
reefer compressor, which is mounted on a shelf in the aft port quarter  
locker, also has a fan.  Either one might be heard (especially in the  
aft stateroom) when all else is relatively quiet.

Due to our problem of zebra mussels jamming the paddle wheel, I Made a point
of painting my paddles this spring when the bottom was done.  Speedo works
fine and so far no zebra mussels to clean off.

John:

Did it work earlier in the season? I'm told that if bottom paint gets on the

paddles, it can affect (or kill) the reading.

Yes, this does have a happy ending ? I have the parts. After
a bevy of emails to Ken and Kent on the east coast and west coast, a letter
to
Frank Butler, and a very nice phone call with Mr. Butler, we solved the
mystery. The parts I needed for #515 are no longer installed on newer 320s.
So
my parts were in storage on the west coast waiting to be shipped to the east
coast.
This is why the east coast guy couldn?t figure out what I was ordering. At
the
suggestion of Mr. Butler, I took pictures of parts I needed and emailed
photos
to parts department. When parts shipment arrived in Florida, just like
magic,
my parts were located.? Moral of
story is: send photos of what you need. Boat models change as do parts. All
the Catalina folks were helpful and courteous to the end of the month and
half
hunt for parts.
Tks for all input comments. I hope this will help you order
parts.
