First sorry for my poor english hehe . I have a problem with my boat. Yesterday a ran 3 hours with the boat and we doesnt have any problem. I put 50 L off fuel and after that the motor bog at idle. When i try to put some throttle the engine stop. After 45 min the problem stop. Today we return in boat fort 3 - 4 hour with no problem but at the end of the day the same problem appear again. Anyone have a solution.
