Raymarine Type 1 Linear Drive – 12V (M81130)

The Raymarine Type 1 Linear Drive – 12V is a precision mechanical autopilot drive unit designed for smaller mechanically steered vessels requiring reliable, smooth autopilot steering. Engineered to deliver responsive control and quiet operation, this linear actuator drive works with Raymarine autopilot systems (such as the ACU-400 control unit) to provide accurate course-keeping and effortless transitions between autopilot and manual steering. The integrated electromagnetic fail-safe clutch disengages the drive when autopilot is off, allowing unhindered hand steering.

Ideal for sailboats, small cruisers, and powerboats with lighter rudder loads, the Type 1 Linear Drive delivers dependable performance and compact design for boats where space and simplicity are key.
