I guess my surveyor missed it but the speed transducer on my 1985 Catalina 30 Tall Rig is missing. There is some sort of blank fitting with a clevis pin in the hull fitting just in front on the master bunk. No wires or anything else. I have an older Raytheon Speed indicator mounted at the pedistal but I can't find a model # on it. The unit is mounted in a white "ball" type of housing. There is a similar housing for the depth meter on the other side of the pedistal. I am thinking that the transducer is a paddle wheel type but I do not know for sure. Does this sound like anything anyone has seen before? Can I get a new or replacement transducer and where would I wire it to the indicator. Thanks
