Powerful Raymarine Type 3 hydraulic linear drive unit (12V) for autopilot systems on larger boats. Designed for mechanically steered vessels up to 35,000 kg displacement. The set includes:

• Independent hydraulic ram: provides direct steering input via an independent tiller arm
• Built-in clutch: allows friction-free manual steering when the autopilot is disengaged
• Reversible 12V pump: high-performance hydraulic pump drives the cylinder
• Fluid reservoir: closed hydraulic fluid system for reliable operation

High-performance Raymarine hydraulic linear drive (Type 3, 24V) for autopilots on large vessels. Suitable for mechanically steered boats up to 35,000 kg displacement. Key components include:

• Hydraulic ram: powerful piston mechanism that drives the rudder via an independent tiller arm
• No-load clutch: ensures the helm can turn freely when the autopilot is off
• Hydraulic pump (24V): a reversible, high-power pump that actuates the cylinder
• Fluid reservoir: maintains optimal pressure in the hydraulic circuit

Raymarine Type 2 hydraulic linear drive unit (24V) for autopilot, suitable for mid-sized vessels. Designed for mechanically steered boats up to 22,000 kg displacement. Features:

• Compact hydraulic ram: provides reliable rudder actuation for boats up to ~22 tons displacement
• Built-in clutch: allows the drive to disengage for free helm steering when needed
• 24V reversible pump: powerful pump optimized for lower current draw and steady performance
• Closed hydraulic loop: includes fluid reservoir and lines pre-filled – simplifies installation and reduces maintenance
