HyDrive's impressive range of manual hydraulic outboard steering is ideal for most applications, however, power steering may be suitable for large horsepower boats that require small turn ratio's with little effort or for people who, for medical or employment reasons, require power assistance in turning the wheel. The system can be installed as a complete unit, or used to upgrade an existing HyDrive manual hydraulic unit that is in good condition. Power steering systems are available for dual stations, single or dual cylinders, catamaran steering without mechanical tie-bars and can include provision for an autopilot.
