[C320-list] Knotmeter knot working

[Bill Sloane]

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.
