The Optimus Electric Steering Actuator is the next evolution in electronic power steering

News Date: March 1, 2021

Propulsion Systems

The Optimus Electric Steering Actuator gives you control like no other, with intuitive and adjustable navigation controls at your fingertips, you can steer your vessel confidently.

The Optimus Electric Steering Actuator mounts directly on the outboard in place of the present hydraulic cylinder. The powerful drive train, position sensor, brake, and electronics are all embedded in the electric steering actuator. This means no Pump Control Module, no hydraulic pump, no hoses, hydraulic cylinders and fluid, and no more purging the system.



The Optimus Electronic Steering Actuator is the first complete bolt on electronic steering for outboard engines, compatible for twin, triple, and quad engines 150-hp and up.


The steering control unit, hydraulic power source, and transmission and actuator are integrated into one electro-mechanical actuator, making this the next evolution in electronic power steering.
