this is going to be a bit long. we sailed motored 2000 miles from guatamala to texas we had some fule filter issues that were resolved but after i got to texas and the motor had run for 6 mointh with no issue. i turned of the engine at the dock and went home to sleep on land. i came back to move our boat to the marina and she would not start just turn over over and over and over. no matter waht she will not start we reprimed and checked the celnoid , glow plugs, fule pump, compresion waht could be doing this to my engine i have no clue what to do next to get this fixed.
