Raymarine EV-100 Tiller Evolution Autopilot Complete Kit

The Raymarine EV-100 Tiller Evolution Autopilot is the complete autopilot system for tiller-steered sailboats - everything needed for a working autopilot install in one package. The Evolution platform is Raymarine's modern autopilot intelligence layer (replacing the older fluxgate-compass-based autopilot generation), and the EV-100 specifically is the tiller-pilot variant of the Evolution architecture sized for boats up to 13,200 pounds laden displacement.

What's in the box - complete autopilot system. The EV-100 Tiller pack includes four major components: the EV-1 intelligent sensor core (the autopilot's brain), the ACU-100 actuator control unit (the power module), the tiller drive unit (the actuator that physically moves the tiller), and the p70s autopilot control head (the helm-side user interface). Plus all the cables and mounting hardware. For boat owners installing autopilot for the first time, the all-in-one pack means you don't have to research and source individual components separately - all the right pieces are matched and included.

EV-1 intelligent sensor core - what makes Evolution different. The EV-1 sensor is the autopilot's brain. Where older autopilots used a fluxgate compass alone for heading reference (which drifts under acceleration, can be deflected by ferromagnetic objects, and provides 1-2 degree heading accuracy at best), the Evolution EV-1 uses 9-axis sensor fusion - magnetometers, accelerometers, gyros, plus optional GPS-aided heading reference. The sensor fusion delivers meaningfully better heading accuracy (typically 0.1-0.5 degrees), no drift under acceleration, and immunity to most ferromagnetic interference. Practical impact: the autopilot holds course more precisely, requires less frequent rudder corrections (extends actuator service life), and recovers faster from boat motion disturbances.

ACU-100 actuator control unit. The ACU-100 is the power module that takes drive commands from the EV-1 and converts them into the appropriate electrical signals to drive the tiller actuator. ACU-100 specifically is the lower-power variant of the ACU lineup (ACU-100 / ACU-200 / ACU-400), sized for the EV-100 Tiller's lower-displacement boat application. Wiring is straightforward - the ACU-100 mounts in a protected location near the boat's electrical system, with cables running to the EV-1 sensor and the tiller drive.

Tiller drive unit. The actuator that physically pushes the tiller is an electric linear drive sized for boats up to 13,200 lbs displacement. The drive mounts externally in the cockpit, with one end attaching to a fixed point on the cockpit coaming and the other end attaching to a pin on the tiller. When the autopilot commands a course correction, the drive extends or retracts to push the tiller to the appropriate angle. The drive itself is similar to traditional Raymarine ST2000-style tiller pilots in mechanical concept but is a separate unit (versus the integrated electronics-and-drive of older self-contained tiller pilots).

Removable tiller drive for storage. The tiller drive uses quick-connect mounting hardware - lift the drive off its mounting points in seconds when the autopilot isn't needed. Useful for: hand-steering in tight quarters where the drive's drag on the tiller is undesirable, removing the drive for off-season storage to protect it from weather, or removing the drive for security in unsecured marinas. The mounting hardware itself (the cockpit-side socket and the tiller-side pin) stays in place when the drive is removed - no permanent install scars on the tiller, just two small mounting points.

p70s autopilot control head. The included p70s is the helm-side user interface for the autopilot. Backlit color display, dedicated keypad with mode buttons (Standby, Auto, Track, Wind), and the rotary dial for fine course adjustment. The p70s is the recreational variant of Raymarine's pilot controller line - sufficient for typical sailing use. For boats wanting touchscreen control instead of the keypad p70s, the EV-100 also works with Raymarine Axiom chartplotters as the control head (Axiom integration is the alternative configuration - the EV-100 ships with the p70s, but you can use an Axiom instead if you have one).

For sailboats up to 13,200 lbs laden displacement. The 13,200-lb spec is meaningfully more capacity than the legacy ST2000 Plus tiller pilot's 10,000 lb rating - the EV-100 covers slightly larger sailboats than the ST2000+ class. Typical compatible boat sizes: 32-foot cruising sailboats, 30-foot performance sailboats, larger trailerable sailboats with tiller steering. For boats over 13,200 lbs, the larger Evolution autopilot configurations (EV-200 with hydraulic drive) are the right call.

Evolution AI - intelligent course-keeping. The Evolution AI is the autopilot's adaptive course-keeping algorithm that runs on the EV-1 sensor core. It tunes the steering response based on observed boat behavior - small corrections in calm conditions to conserve battery and reduce actuator wear, more aggressive corrections in heavy weather to maintain course in confused seas. The AI also handles sail-specific situations: AutoTack initiates a tack maneuver while the operator handles the sheets, and the algorithm keeps the boat on course during the tack with minimal speed loss.

SeaTalkNG and NMEA 2000 networking. The EV-100 connects to the boat's network via SeaTalkNG (Raymarine's modern network) or NMEA 2000 (the open standard). Network compatibility lets the autopilot use data from connected sailing instruments (true wind for wind-following modes), chartplotters (route data for waypoint-based navigation), and AIS receivers (collision-avoidance integration). For boats with mixed network ages (older SeaTalk plus newer SeaTalkNG / NMEA 2000), the appropriate adapters bridge the protocols.

No complicated setup or autopilot calibration. The Evolution platform's signature simplification: no manual calibration, no swing-the-boat compass calibration, no extensive parameter tuning. The EV-1 sensor core auto-calibrates as the boat moves through normal use - the autopilot learns the boat's specific characteristics over the first few hours of use and tunes itself appropriately. Compared to older autopilots that required hours of manual calibration and ongoing parameter tweaking, the Evolution platform is meaningfully easier to install and operate.

IPX6 drive + IPX2 control head waterproof ratings. The tiller drive unit is rated IPX6 (protected against powerful water jets - handles wave splash, washdown, heavy rain in cockpit-exposed location). The p70s control head is rated IPX2 (protected against drips - typical helm console install where direct water exposure is unlikely but humidity and drips happen). Both ratings are appropriate for the typical install location of each component.

DIY installation. The EV-100 is engineered for owner installation. The included documentation walks through the install step-by-step. Required skills: basic mechanical (mounting the components), basic electrical (wiring the SeaTalkNG / NMEA 2000 cables), and the ability to follow the wiring diagram. Total install time is typically 6-10 hours for a competent boat owner, dominated by routing cables through the boat's wiring chase to the cockpit.

Two-year limited warranty. Standard Raymarine warranty terms apply.
