in the hull there are two holes that have been plugged with wood. I've been told by the surveyor that that is where the transducer and the 'prop' (or whatever it is) goes on the other. I was going to pull those plugs out and rewire...rrr cable those devices. Any idea on what the replacement cost is for something like that. Not looking for top of the line, but not at the bottom either. Thanks.

Holes

I personally do not like any more holes in the hull than absolutely necessary. If you want a speed instrument, then a thru hull is necessary. If you don't find the speed instrument a necessity then you can do away with the holes completely. A depth transducer can be placed inside the hull, and will work just fine. I have a hawkeye depth in my boat. The transducer epoxied inside the hull. Works good, no danger of it getting knocked off, and no thru hull fitting. As for boat speed, I use a GPS, which gives speed over ground, but not speed through water, which I don't find necessary for me. You can tell if a inside transducer will work on your boat, by putting the transducer in a baggie of water and sitting it in the bottom of the hull. Move it around till it gets a good reading and then use a good epoxy to stick it down in that spot. I used Marine Tex on mine.
