I had a tracker tx17 with a 90merc. Pulled three transducers off. After calling Hummingbird engineering suppport. Moved transducer to left rear to prevent steering torque and high up to prevent it from being ripped off no problems. Keep in mind its a skimmer and you may need to tilt motor to see side image on both sides. If you have a jack plate place it on the jackplate for best results. Hope this helps. If you need any more help just drop me an E-mail.Its a lot of trouble but once done its worth it.
