Transom Mounted Transducer Placement

[ScottM]

Hoop,
I mounted my 'ducer to the inboard-most side of the 2nd chine (see pics on the 23' page). I wanted it as deep in the water as possible without getting too close to the engine. As it turns out I don't get any reading beyond 18-20mph so either it's too far out of the water on plane or there is too much intereference by the engine. It's not the end of the world though since we also have an old Koden color CRT with a thru-hull 'ducer that reads at all speeds.
