I have installed many puck style transducers on bassboats in the past and the two part epoxy works the best. It is imperative that the transducer sits parallel with the bottom of the vessel and that there are no air pockets under the transducer nor air bubbles in the epoxy.

Before you begin reaffixing you transducer again, you may want to clean you connections on both the power and transducer cables and the sockets on the base unit, then apply a liberal amount of di-electric grease to your connections each and every time you go out. This will improve the conductivity and reduce the amount of saltwater getting into your connections.

The exterior mounting technique noted in the above post is similar to the exterior mounting of a transducer on a trolling motor, which is truly the best way to go for the best signal.
