I hate the thought of holes in the hull. ? I also mounted mine as far aft under the V-Berth as possible on centerline.? Instead of an epoxy or silicone puddle, I fitted a threaded 3" PVC female pipe fitting to the hull to make it plumb, and then epoxied that in place.? I then filled the fitting with mineral oil and screwed the transducer in mounted to a PVC pipe plug.? No problems in 2 seasons, but I was carrying around a couple ounces of oil if?I needed to top it up.? Been reliable enough that it didn't make the on-board race kit for this year.

It worked great. You do loose some sensitivity but only on the "deep" side. ? I mounted?mine under the V berth as far aft as I could get it. ? It will only work if there?are NO air pockets (however small)?between the transducer and the water, either in the hull (won't work with a cored hull)?or your installation. ? I used a "beer" cup for the installation. I sanded the gelcoat/paint off the interior hull surface and wiped it down with acetone. Then cut the bottom out of the cup and siliconed it (upside down) to the hull and suspended the transducer in it with a wooden dowel and some string.?Then (careful not to "whip" in?any air) mixed some slow cure west system epoxy and filled up the inverted cup. ? On subsequent installations for customers, I used?a short length of PVC and beveled it so as to make it?plumb and not 90 degrees to what ever angle the hull is. Also the epoxy my cause (thru heat or chemical reaction) a "beer cup" to melt. I got lucky in that the epoxy cured before my cup completely melted. It was ugly but it worked. ?

If so, where did you mount it? All the best Earl s/v Nautidog C27 Traditional #3188 Old Point Comfort, VA Internal Virus Database is out-of-date. Checked by AVG.
