Hey guys, I appreciate this forum and the chance to get some good advice. I recently purchased a Helix 9 si unit and am in the middle of installing it. I'm down to the Transducer location and just wanting to make sure I get it right the first time. My boat is a 97 procraft. It's pretty much identical to the boat in the first pics in the installation gallery. I am wanting to mount it on the step below where the one in that pic is mounted to possibly keep from having to run 2 transducers. My previous transducer was mounted there and I would get depth readings while on and off plane. Does this seem logical or should I bump it up and plan to use a shoot through for running. Also I've seen several pics of transducers mounted closer than 15 inches to the motor. The instructions say to keep it farther but obviously that isn't always the answer. Thanks in advance.
