You may need to tighten the mount a little. Mine has popped up before and just needed adjusting. I would bet its fine. Rule of thumb of course is the horiz. center line of transducer should be level with the bottom edge of the hull. But the SI transducers usually need to be a little deeper so they dont lose bottom lock at high speed.

Post a picture of your installation and I am sure you will get some feed back. You can certainly stop by the SI forums and there are a lot of guys who could give you some more advice on placement.

Good Luck,

Robert
