We left Caleta Lobos about 9:30 a.m. and headed out intending to go to Caleta Partida on Isla Espiritu Santu however just after exiting Lobos we had issues with the engine and quickly raised sail to clear the rocky outcrop of Roca Lobos so we could investigate the problem. Engine checks were made and everything was OK so John put on his mask and dived on the boat in the 70 degree water to check the propeller in case we had picked up some rope/line but everything was clear. As the engine was continuing with issues at anything above 1,200 RPM and because we were still close to La Paz we decided to sail back to the Marina to at least have calm water and a dock to work on our problem. Engine fuel filters are the most likely cause; 90% of diesel engine problems are related to bad or dirty fuel.
We had superb sailing back to the Marina in winds of 18-20 knots slightly aft of the beam. The seas were about 2-3 feet but running behind us as we sailed under full main with a shortened Genoa. It gave us a chance to relax, enjoy some fine sailing at over 6 knots. We arrived back in the marina safely and tomorrow will be a day of engine work as all of the diesel fuel filters are checked or replaced.
