I need to replace either my keel pivot bolt, or at the least the washers, on my Macgregor 25. I had the normal problems assessing the problem. Remove the water in the bilge. Done. Assess the quality of the packing material. Needs replacement. Remove boat from water. Done. Remove bolt from boat. It was about this time that Murphy arrived. Most tools were about 45 mile from the boat, including those necessary for the removal. I want to buy a new bolt with new rubber washers, and new aluminum washers, before driving back to the boat. Can any one tell me what size of bolt, etc.? ANdrew
