Mine just arrived. Getting ready to install! A question I have 1996 Ranger 451 v Comanche the turbulence at the transum prevents exterior mounted transducer . From the past installs I loose video or the picture on my unit once on plane running faster than 4 mph. Thus I must do a shoot through hull mount with epoxie ! Do you all agree? Will I loose some clarity scensitivity etc? Any other ideas? On mounting the 2 d transducer? I start the install by first removing the old transducer epoxied now. Plan to be carful and use a grinder with a fiber blade and try and cut it out? Just rambling thanks lb
