Do you mean to glue it to the inside of the hull? If so yes. I also have Humminbird and they told me that the transom mount transducer that it comes with is what you are supposed to use for shoot through the hull (glue in). I also used silicone as my glue, epoxy
is recommended. You have to order a drill a hole in the boat transducer separately if that is what you want from Humminbird.
Agreed with above, any cored hull means no shoot through, unless they have provided a solid hull place for the depth sounder
. I've read that some do.
You can buy an extender cable to mount the transducer farther forward in the boat and that is the ideal and can be useful. But, the transducer I have is a 20 degree cone angle. At a flat bottom depth of 6 feet that means it is looking ahead maybe one foot, probably more as it's not an on/off function. How slow do you have to be going to able to stop your boat if you detect a ledge or a rock in front of you when it is the distance of the transducer in front of your keel
plus a couple of feet?
