Hey all,
We have a new to us 2003 Four Winns 260H engine 0M621773 and drive 0M149309. When we bought the boat the steering was stiff so I rolled the dice on the steering cable being bad. Replace the cable and the rotary helm and it did not help. It was almost impossible to turn. I pulled the pins to check both the steering cable(the new one) and move the drive both of which are easy to move with no resistance when you move them. I put the pin back in the steering cable at the ram and ran the engine and it feels like there is no assistance from the power steering pump. When I put the pin back in for the drive and turn the wheel with the engine running if felt like it was "sticking" and occasionally the pump would help. I pulled the actuator and seperated the tube and there were small black particles inside. I cleaned the tube and worked the valve with marvel mystery oil and it seemed like the valve was functioning correctly. I then flushed the pump and lines with marvel mystery oil and then Mercon V fluid. I reassembled everything and bleed the system by hand before starting the engine. Now when I run the engine and turn the wheel it still feels like the pump is helping occasionally but when I turn it back from lock to right the actuator will shudder hard enough to shake the whole boat. If I move the wheel slowly it does not do it. I am thinking that maybe the pressure valve in the pump is stuck or sticking? Any help is appreciated!
