Re plugs: I've had 14 boats with many holes in each of them and have yet to have a problem other than stuck valves. I have installed many transponders in all kinds of boats, and I have yet to see a properly installed through hull transponder leak or cause any problems. I think the fears of drilling holes in hulls are unfounded. Just sayin'...
