Known for its proven reliability, this cockpit-mounted actuator delivers a fast response time with a 4.0-second full-stroke rudder movement. Weighing 1.778 kg, it provides an optimal balance between power and weight for course-keeping in varied sea conditions.\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and positioning\u003c\/h3\u003e\n\u003cp\u003eHistorically paired with ST4000+ and SPX-5 autopilot computers, this actuator is now the standard power unit integrated in the popular Raymarine EV-100 Tiller autopilot pack. Unlike mechanical linear actuators (type 1) or hydraulic systems that require installation below deck on the rudder quadrant, the ST4000 T installs directly in the cockpit. This setup ensures simplified maintenance and quick removal at the harbor, while offering a cost-effective and high-performance alternative for mid-sized sailboats compared to more complex in-board systems.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation specifications\u003c\/h3\u003e\n\u003cp\u003eStandard installation of this actuator requires two strict kinematic dimensions: a 620 mm (24.5 inches) distance between the mounting base and the tiller pin (dimension A), and a 460 mm (18 inches) spacing between the rudder stock axis and the tiller pin (dimension B). To accommodate the complex geometries of different cockpits, Raymarine offers maximum modularity. A wide range of compatible accessories can be added, including rod extensions (part numbers D003 to D008 ranging from 25 to 152 mm), cantilever brackets for mounting under or on the tiller (D009 to D160), and elevated mounting bases (D026 to D030). This flexibility ensures perfect alignment of the thrust, essential for optimizing power consumption and motor lifespan.\u003c\/p\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":53723809022292,"sku":"Q047","price":702.72,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/raymarine-q047-tiller-drive-official-1600.jpg?v=1784802322","url":"https:\/\/skysat.fr\/en-gb\/products\/raymarine-st4000-t-tiller-pilot-linear-actuator-12v","provider":"Skysat","version":"1.0","type":"link"}
