Re: How to install an in-hull transducer
For an in-hull (also known as shoot-thru) transducer, you don't have to drill any holes. If you mean a thru-hull transducer, then you do.
I suggest following the instructions that come with your transducer, but the short of the long of it is this:
1. test spot for accurate readings both stationary and moving (you'll probably need help). There are a few different and well documented methods to do this.
2. clean and prep hull bilge surface at your desired mounting point.
3. mount transducer to hull using slow-cure epoxy or other suitable adhesive.
Is is hard to do? Nope, I didn't find it hard at all and I'm sure you can do it too. The only thing that could make it difficult is if you have a very hard time getting at a usable spot in the bilge due to the boat's design. Cored bottoms are generally a no-no with in-hull transducers as well, or, if there are voids in your boat's fiberglass layup where you want to mount the transducer. These will result in erratic and inaccurate readings.
