O.k myself and Steve (67hat34c) both have 34C's and have or transducer a little back from the forward bulkhead. Both of us get a lot of air bubbles when going fast. Mine was beautiful until my repower so the boat is out of the water more.
So we have to move them back some so I am looking for ( How far back do I go)? I am thinking about the area near the Transmissions. Anyone with a 34 or 36 that cruise at 20 kts or above have any suggestions from where theirs are placed.
