Specs At A Glance

Good To Know

Q: How do I know this cylinder matches my steering system? A: Compare the cylinder mounting pattern and port fittings against your existing hydraulic steering unit before ordering. Helm and hose ratings should also match the 300HP capacity of the cylinder.

Q: Is bleeding required after installation? A: Yes, hydraulic steering systems must be bled of air after any cylinder replacement. Follow the helm manufacturer's bleeding procedure and top off with the recommended hydraulic fluid.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
