Tommy... Looks like to me you should be fine...

The HDSI xducer is longer than your existing xducer (about 5 inches I think).... But your clearance looks more than adequate....

Like I mentioned before.... Install your xducer and start trimming your motor down as you watch the full screen SI...blockage will be noticed on the side of the image that is being blocked...

Blockage will be evident when the side of the image being blocked starts to look noticably different from the other side of the image...

If I remember correctly blockage makes the side being blocked noticably darker than the other side of the image...
