I hooked up my hummingbird this way, works like a charm. i put it in a bag of water(which im not sure if you need to do) and moved it around till i liked reading, removed from bag and epoxyed it to the fiberglass (after a decent cleaning), when i pushed it down into the epoxy, i kinda used a twisting motion to get rid of any bubbles. there is another method with mineral spirits filled pvc but i didnt go that route. what your boat is made of is a consideration, as well as not forgetting to offset the unit to keel depth.
mine is in the engine compartment, but i use that unit primarily for fishing from the cockpit, and do have redundancy via thru hull unit. if you are worried about grounding id put the transducer toward the bow to 'see' what is in front of you.
edit: while i maybe off base, i believe the number of 'beams' affects size of area you can view-spinning the transducer wouldnt affect the range, persay just make everything on the scrolling display be backwards... i think~that last bit was giving me a headache... lol.
