[C320-list] Engine Temperature Sender location

[Daryl Hunt]

Thanks Graeme.  That was my first guess, but when I ran step 2 of the 
test procedure contributed by Jeff Hare 
<http://c320.org/article.php/2012072022490543> (and also CatalinaDirect 
<https://www.catalinadirect.com/index.cfm/feature/161/temperature-gauge-test-procedure.cfm>), 
the temp gauge needle did not peg to the right when the sender wire is 
grounded.  I think there was a PO modification I need to track down.

Fair winds,
Daryl

The coolant is being circulated around the engine block but only when the thermostat opens will it go through the heat exchanger where it is cooled by the raw seawater that is pumped through the other part of teh exchanger and into the exhaust

Here's a link to pictures on my Google drive <https://drive.google.com/open?id=0B4Mdc10lhKTienl6djhsdkpNVzg>.  I'm not confident this location would give me an accurate engine temperature.
