Ok here's the deal, I bought a 1979 ranger 168v. It def needed some cosmetic work(seats,carpet,) but when I bought it, the motor ran great.. Used it for a year and motors cylinder 3 piston ring shattered, ugh. Put a black max 175 on it, got it going and runs great, with 150psi on all 6 cylinders. Started noticing water in the back by the batteries, the drain plug was in it, always check that. Tool the boat home, put the plug in it, and started filling water up in the boat to check for leaks. Then it happened.... Water started leaking on the bottom point in a few spots, not pouring out, but for sure leaking. Looked and seen where awhile back someone put some fiberglass resin and sheets to patch it. I bought some marine Tex, heard that was the best? What is the best procedure on patching these spots?? I don't wanna have to keep fixing the cracks, I just wanna fish and not have to use my bildge pump, lol. Any ideas would be greatly appreciated. Thank you
