[C320-list] Knot meter transducer

[Jeff Hare]

Crosby, 

I replaced mine a few years back.  I believe you should be looking up
Airmar. 

Anyway, either search for "airmar" on the C320 website or go here:

I found what I needed on the Airmar site and then purchased one through
Defender online I believe.

One thing I did notice when replacing it, the new ones have a feature I
don't like.  The new ones lift the paddle wheel as you unscrew the ring to
jack up the unit so that it comes out easier.  The old models you could hold
the paddle wheel down, fully loosen the ring, then Pull the paddle wheel
with one hand and replace it with the plug in you other hand in a one quick
motion. So, I only got a splash in the boat.

The new one lets in a lot more water during the unscrewing process.  

Anyway:  www.airmartechnology.com

Subject: [C320-list] Knot meter transducer

The paddle wheel on my knot meter transducer has corroded badly since I last
used it. I checked on the raymarine site for a replacement and could find
nothing; West marine seems to sell the whole unit for between $200-400. I'm
looking to just replace the insert part rather than the insert and sleeve.
Can anyone point me in the right direction?
