Another transducer mounting question

Fiberglass boat. Would you epoxy it in the hull? Mount on a piece of starboard, on the transom? Mount on the jackplate?

Some pictures for reference -

The graph is a Garmin stryker 4.

Bilge mount for 2d thru fiberglass is a good option ...

SI or DI need to be in the water ...

Some are even lucky enough to get good 2d digital depth from a transom mounted SI/DI xducer - but it’s challenging (due to SI/DI xducers being brick shaped and not very hydrodynamical) ...
