I recently installed a transducer mounted on the back of the Javelin Renegade 20'.
Left of the motor. I am reading turbulance while on plane and the graph flashes. Due to the different steps in the transom, I do not see a better place. Does anyone have a picture of how yours is mounted. Option 2 would be to epoxy it on the inside. Does any one know if there is styrofoam between the hulls?? will this work

Thanks
