Does anyone know the torque specs for the keel bolts on a 1969 Coronado 25? I understand that this may be a sister hull to the Catalina (Columbia??) 25 of the same vintage. Although mine appear to be in good shape, rumor has it that this could be a weak point for this boat and I would like to double check them during haulout. Beyond staring at them from the bilge and imagining corrosion monsters below, is there any other way of checking keel bolts besides torquing them?
