We have a backup Type3 Robertson pilot pump with larger cylinder in our J42. It is oversized and does not steer as well as the Type2 system. The Type 3 cylinder space on the quadrant is needed for the new Cape Horn vane tackles.
Any reason not to replumb for twin Type 2 pumps teed to the Type 2 cylinder? Only one pump at a time can be plugged into the Evolution controller. The single
NO solenoid bypass also teed in. Brushes
are the most common offshore
breakdown, and a spare parallel pump would be great to have ready to go.
