    I am saving my money and will get a new thu hull depth (mine is non functional) and
    speed & temp but until then I need a good way to measure depth I would like to get a in hull depth finder in the bow Close to where my thru hull is, in the v-bearth, is there any core material I need to be wary of. any one have a recommendation ? installation problem ?

    I am also faced with replacing a depth sounder and most of the electronics on Silverheels (hull #17). I have purchased a B&G Multi Function display package from which includes a DST800 in plastic housing which will leverage the NMEA2000 protocol and wiring. The plan is for the old transducer to be pulled out and replaced with this unit. I hope to work on this in about two weeks and will share how it goes with this forum.

    I too am looking at a b&g, in the meantime would like to use a temporary depth sounder that goes in the boat, until I have the cash for the b&g

    The old depth sounder was all one piece and we had to remove it by sanding down the residue around the depth sounder on the outside of the hull and then pushing the through hull down and outside. Once the old through hull was out, we found that the thru hull was a standard size and would fitting the new DST 800 would be no problem. After doing some research and speaking with some experienced sailors in Green Cove Springs Marina, I decided to used 3M 4200 Marine Polyurethane fast cure sealant. This was smothered around the lip and the bottom 1/3 of the through hull threads. As I hand tightened the through hull screw from inside the bilge, a person outside the hull was cleaning off the excess sealant that was forced out.

    There was one main gotchya I forgot to look for the little arrow on the through hull that was meant to point forward for the benefit of the speed sensor/paddle wheel. I had it pointed athwart ship…oops. Luckily I ran into a friend within So re-setting after 15 to 20 minutes of curing made the job difficult…especially hand tightening over the fast cure sealant that had started the curing process…I was sweating like a monkey in the bilge with every quarter turn.

    I’m still working on setting in the new gauge and running the NMEA 2000 backbone wire up to the inside of the cockpit combing.
