[TG] ST60 Erroneous Speed Indication

[mmichaelbrown]

When the boat was delivered (Leopard 43) boat speed worked perfectly. Moorings never maintained this function so when I took delivery it was not working, I assumed it was fouled. Not so, transducer gives correct speed when hand held in water (different location), at the location where it has always been indicates max 4.5 kts.
Two questions:
1. How far should the paddle wheel protrude from the hull (small chance transducer was "re-attached")
2. My transducer housing is cracked, where can I get just the housing?

Thank you
