Does the engine run? When I worked the Pensacola harbor tug we used to make the run to New Orleans in around 24 hours via the ICW at 8-9 knots. You can make the entire trip on the inside, I would just get her home using the most risk conservative method (ICW) that you can. If you have problems you can tie up somewhere, fix it and then continue, running outside with an unknown boat kinda limits your options.
