Inside Hull Transducer Mount

[gregst7]

I have a Humminbird Piranha 215 with a suction cup transducer mount. The problem that I have is that kayak turns to one side when paddling with the transducer mounted to the outside hull. I am considering mounting the transducer inside the hull and am concerned that I won't get all the readings - temperature, fish-id, accurate depth and structures. I've read about all kinds of mounting procedures. My question - will I lose any of the fishfinders readings when mounted inside the hull?
