Just get a steel-lined replacement bushing that screws into the trunk. Available from any marine supply (West Marine, Defender, etc. or your local chandlery). That will work with steel cable or rope. In replacing bushings, I try to make them as small as possible without binding on the cable/rope. That minimizes splashing.
Roger suggests actually threading the hole and replacing the bushing with a brass or plastic plumbing fitting that goes all the way through the hull and includes an end cap that blocks almost all water from the cabin. See his book on the topic.
