[C320-list] Knotmeter knot working

[Allan Field]

Bill - Sea Shadow's hull knotmeter has never seen water.  We have the
complete Raymarine SeaTalk instrument system including color chart plotter
so this gives us boat speed.  I believe that the only thing missing by not
having the knotmeter in is being able to read true wind but apparent wind
works for our needs as we don't race.  Where we are on the Chesapeake Bay,
the knotmeter on my old boat had to be cleaned every week.  Once I got GPS,
I never used the old knotmeter again either.

Forum:

Having never owned a boat with a through hull knotmeter, I am not clear how
to fix one.  It was not working this past Sunday when I went out for a
chilly but beautiful sail. A colleague at work told me that I need to
unscrew the fitting in the V-berth sump, and immediately screw in the spare
fitting that is tethered there.  Is this in fact how you do
it? Isn't that opening a hole in the hull below the water line?

I am pretty sure a crustacean or other volunteer has made a home up in the
little fly wheel that needs to be dislodged. Can I do this by entering
through the sump?

Appreciate any advice.
