So another project I have between now and spring launch is installing a thru-hull transducer. Can anyone tell  me if the bottom of the hull of my '96 Gulfstream is cored or not? From the transducer instructions it looks like the process for a cored hull is more involved, still doable but probably not a one-day job.
Thinking spring,
