Tony,

Q. Is it hard to bleed the system once the pump is replaced? Or is just cycling hard port to hard starboard enough to bleed?
A. It is indeed not hard to bleed the hydraulic steering system. Good vessel maintenance would include regular replacement of the fluids and lubricants within the vessel's engine(s), steering, and hydraulic system. When replacing the pump, this would indeed be a good time to replace the fluid within the hydraulic steering system. There are a number of good videos on YouTube addressing how to change out and then bleed the steering system. The Bleeding the system section of Chapter 5. Post-installation check of the Hydraulic Pump Installation Guide calls for following the instruction of the hydraulic helm manufacturer when bleeding the hydraulic steering system and that afterwards follow the additional instructions provided within this section of the Hydraulic Pump Installation Guide.
