I bought a 1986 tracker and restored the decks and added my touch but could not find the leak which caused the bilge to be used every 45 minutes. I googed every rivet and external screw on the boat. Last week I was down to the aerator hose. Maybe water froze in it over the winter and burst. Well, that was it but not freezing water. When they installed the transponder, they hit the hose with one of the screws. With all the foam, it probably took years to start this major leak. I dug out all the foam in the back and rerouted the hose and all is well. Just thought I would share this with you guys with old trackers or leaky boats. I now have my faith in them back. All it took for the old 35 Merc was a new impellar and I have a great 16ftr. About $3.5K invested. Hope to get to Kerr later this year when the crappies turn on again with my grandsons from Raleigh. I live in Clarke County VA. Great site. I learn a lot here.
