Engineered for simplicity, Raymarine's award-winning Evolution autopilots eliminate the need for complicated set up and calibration. Thanks to the intelligent 9-axis EV sensor core, the autopilot automatically evolves and adapts to your vessel's steering characteristics without any user adjustments. The result is precise and confident course keeping, regardless of vessel speed or sea conditions. The Evolution EV-150 system also employs Raymarine's patented Hydro-Balance technology which delivers superior autopilot performance for hydraulically steered boats, particularly those with outboard motors and rudder-reference less systems. Hydro-Balance automatically compensates for hydraulic system elasticity, steering system asymmetry, and torque steer to keep your boat on-course at trolling spe.
