[C320-list] Airmar CS4500 replacement for speed paddlewheel?

[Jeff Hare]

Hello,

My speed sender seems to have died. Still getting temp readings but no speed.

I read from raymarine's website that the airmar cs4500 ultrasonic speed transducer is compatible with the st60 (and others) .

Has anyone done this swap? The only comment I read regarding replacement compatability was that the st40 thruhull fitting was too long. So is the st60 thruhull a direct fit?

I suspect the paddlewheel version is also made by airmar?
Sure would be nice to not have to mess with clogged paddlewheels.
