I sent a reply Dave. Evidently you did not see it.
There are lots of techniques like this for mounting transducers in the hull. The surface doesn’t really need to be especially smooth, but clean is good. The important thing is that there are no air voids between the transducer and the water outside the hull. That means that the hull must be solid fiberglass (no wood or foam core). And whatever you mount the transducer in can’t have any bubbles. On one end of the spectrum people talk about using wax from a toilet ring, which is effective but not very permanent. Epoxy is the other end of the spectrum - very permanent. Color, mix ratio, etc. should not matter. They probably recommend slow hardener so any air bubbles have a chance to escape before curing. Other frequent suggestions are things like containers of mineral oil and caulk.I have been watching a video on installing an in-hull transducer for my depth sounder. It stated to sand the inside hull with 30 grit sand to get it smooth, then clean with alcohol and glue to the hull with 2 part, slow drying epoxy.
Question:
Does the epoxy need to be clear or can I use white? Does the color of the epoxy interfere with the transducer‘s performance?
Thanks

I mounted a Lowrance transom mount transducer in-hull once. Worked just fine.Will mounting a transducer "in Hull" still enable you to use all the functions? I bought a Garmin fish finder and thinking of doing an in-hull installation instead of the transom mount since the Catalina is already in the water.
We had vinyl letters printed.When you had the name of your boat put on, did you have it painted or stencil? I think I am thinking about having it painted on.

Same here. Looking to replace them during winter refit.We had vinyl letters printed.
