Raymarine Type 2 Linear Drive 12V M81131
Raymarine Mechanical Linear Drives
|
Our most commonly used drive types for sailing vessels.
Raymarine mechanical linear drives provide powerful thrust, fast hard-over
times and quiet operation. Mounted below decks, the linear drive moves the
rudder directly by pushing the tiller arm or a rudder quadrant.
A linear drive unit connects to the rudder stock via an independent tiller
arm. Accessory fittings from your steering manufacturer may be required.
Must be able to back-drive steering system from the rudder. |
