Had same problem with used Bass Cat Puma FTD 2009, call BCB and he told me that puck needed to be about 2 1/2 Inches in front of drain plug, when I looked it was as far forward as you could place it. You could tell that a puck used to be where it was meant to be, I replace with new and now it reads well up to 72, then it drops out, good enough since at anything above that my driving skill are lacking.
