The mounting rings have been glued in and cured for two days.

To insure perfect flat surface contact of the transducer to the hull, aluminum discs are included with the kit. A small dab of epoxy is placed on the underside of a disc and placed into the mounting ring. The transducer is coated with vaseline and screwed into the mounting ring. The transducer exerts pressure on the aluminum disc forcing the epoxy on the bottom of it to spread into any gaps, creating a solid contact with the mounting surface.

Will let the epoxy cure for several days before wiring the transducers and turning the system on..

The epoxy normally cures overnight but current temperature inside the boathouse is 40 degrees and the surface temperature of the inside of the hull is around 47 degrees. To be on the safe side, I have heaters running in the compartments where the transducers are mounted and will allow the epoxy to cure for several days.
