I have a 95 hydra sports bass boat that is fiberglass. My dilema is this. They makers glassed in the transucer for the depth finder and now its leaking, but its not leaking in the bilge it leaks around the transducer on the bottom of the boat. Here is the question. Is the hull a solid piece of glass or is there wood in between layers? If there is just glass then the water is being held in the compartment created when they glassed in the transducer and I won't worry about it, but if there is wood then I need to patch. HELP!!!!
