[C320-list] Shake-down cruise

Thu Oct 2 09:23:06 PDT 2014

Bill, 

What I'm implying is that sometimes it will and sometimes it won't.  I've
seen this on 3 boats. It isn't a sign of anything you need to worry about.
Mine does it sometimes and not others, so there may be some reason for it,
but it is most likely related to the design of the tach.  It could also have
something to do with differences in grounding points and ground potential.
But really, don't sweat it.

-Jeff

But the tach does drop to 0 when the engine is off and the boat is not
moving so I'm still confused.

It is common for the tach to not return to 0 when you shut of the engine. It
isn't related to the prop spinning fortunately.

was reading around 500-600 rpms. I assumed that this was due to the prop
turning with the boat in neutral. Don't really know.
