I brought the rental car back to Enterprise at the Marathon air port at 9 AM then they brought me back to the marina, that is a convenient thing about Enterprise, they will pick you up to get the car then drop you off when you return it.
Then I changed the oil (4 gal.) and filter on the Cummins (main) engine. We had lunch at a BBQ place across the highway from the marina. After lunch I changed the fuel filters on the Cummins engine and the generator.
It has been warm, low 80', and cloudy with rain in the evening. Miami and central Florida had some bad thunderstorms but happily they did not affect us. Dinner on board.
