Out on charter this weekend, we lost our hydraulic steering and had to use our throttle's and transmissions to get back in normal day in our world. Once I had a minute to investigate the problem, we realized that we had run out of fluid, probably due to an extremely slow leak at the cylinder, the actuator the rudders. I installed new fluid re-pressurize the system, bled the system and got it back up and running. Found an extremely slow leak in the cylinder which I may pull out and get rebuilt. I think I rebuilt this myself about 20 years ago so for now, and probably the next 20 years this will solve the problem.
