RE: Shoot through hull transducer

I have a "shoot through" transducer as well. I am using a standard Garmin through hull plastic transducer for my 3210 comob chart plotter. I cut a 4" piece of PVC pipe at the same angle as the hull. Then applied some 3M4000 goop to the angled end and wedged it in place to cure. I cut a hole in a 4" PVC pipe cap and mounted the transducer through this. Filled the pipe with water (I have heard mineral oil works good for this as well and won't evaporate) mounted the cap with the transducer immersed in the water and it works great. No additional hole in the hull and no junk gettting caught on anything protruding through the hull. The only drawback is that the water temp is not accurate. The water temp hardly changes around here anyway so no big dea.
