“Gray Hawk†(#815 w/wing keel) has the original Kenyon depth and knot instrumentation that was installed by the original dealer, I guess. We have only owned the boat 2 years, so I don’t know the complete history. The knot meter works fine, but I have no confidence in the depth sounder. When we are in relatively shallow water it will show 5.7’ constantly. I don’t remember it ever showing less, even when I knew we were in shallower water. As near as I can tell it displays the proper depth in deeper water. Its minimum seems to be 5.7’. Before I install a new sounder, does anyone have any ideas as to what might be wrong with the old one and can it be corrected?

I did a web search for PetroScrub, and found the following:
an article from the Chesapeake Catalina Yacht Club (click here (http://www.aztec.com/ccyc/nl0496.html) and scroll down to "MAINTENANCE TIP DIESEL FUEL TANKS")
a listing of tank cleaning outfits in PA (http://www.envirodirectory.com/Mid-Atlantic/index/svcs/2170.html)
and a few other listings of the same company.
