This kit replaces the old unit with a Mk II drive, integrating the technology of Raymarine’s Evolution autopilot range. It provides a solution to extend the lifespan of existing ST4000 systems by improving the performance of the rudder control unit.\n\u003c\/p\u003e\n\u003ch3\u003eCompatibility and Technical Specifications\u003c\/h3\u003e\n\u003cp\u003e\n    The drive wheel unit included in this kit is compatible with wheels featuring 3, 4, 5, 6, 7 or 8 spokes. It is designed to operate with steering systems having 1 to 3.5 turns lock-to-lock. The unit has a front cover diameter of 228 mm (9.0 in) and an overall diameter of 361 mm (14.2 in). Its height is 135 mm (5.3 in), with a motor shaft diameter of 48 mm (1.9 in) and a length of 171 mm (6.7 in), requiring an additional 60 mm (2.4 in) clearance for the cable. This unit integrates with the existing ST4000 autopilot controller, offering a targeted upgrade rather than a full system replacement.\n\u003c\/p\u003e\n\u003ch3\u003eInstallation and Kit Contents\u003c\/h3\u003e\n\u003cp\u003e\n    Installing the drive wheel unit involves securing it to the wheel using the pre-drilled spoke clamping holes in the front cover and connecting it to the existing control unit.
