The only solution I can think of for this situation is a second transducer that can be mounted inside the hull or through the hull forward of the step to provide readings at high speeds.

I have a stepped transom on my boat but the aft most step never quite clears the water on my boat. There is a lot of noise, but I still can get depth readings while on plane at the speeds I prefer to run.

I agree about the Step Keith. After I put the "splash guard" on the transducer and eliminated the roostertail, I can now read bottom at WOT (35mph). This splash guard helped a lot.

Aqua dynamics for the puck needs improving. Is there such a thing?
