I did a check following your guide on my paddle wheel and had 4.6V on and off as we slowly turned the wheel. However we get 0.0 Kts readings on the multi display ST50. How can I test the ST50 or is the transducer faulty? Mine is an Airmar (ST800?)

Welcome to the Raymarine Forum tstano,

Please click here to view a FAQ addressing this subject. The test referenced within this FAQ does not call for a voltage test. Instead it calls for a resistance/continuity test. Should the test match the results specified within the referenced FAQ and the ST50 Speed/Tridata display that the transducer has been interfaced to not report speed, then the display would be deemed to have suffered a failure and would need to be replaced. Within Raymarine's current instrument products, the i50 Speed and i50 Tridata instrument displays support speed through water.

Yep, my transducer failed continuity. I will contact Gemeco via phone. Thank you.
