I recently developed a leak where my keel cable comes into the boat I opened it up to see if there was any worn out parts in there but there wasn’t just an empty cylinder that the cable ran through it was capped on both ends with a small whole the size of the cable that it ran through and a little bit of oakum left in the cylinder the cable was damage is it possible that all I need to do is replace the oakum in the cylinder and get a new cable to prevent this from happening again to stop the leak ? the boat is a 1974 clipper marine
