Combi E-Thruster electric outboard engines are characterized by their robustness, sleek design and reliability. Our motors have been developed for long-term use and have a high efficiency. The Combi E-Thruster line uses Asynchronous AC motors and synchronous Brushless PM motors, making them very user-friendly and continuously variable. The fact that they are brushless also makes them low-maintenance.

The Combi E-Thruster is a silent motor for optimal sailing pleasure, available as standard outboard model and tiller steered in both short and long-shaft configurations.
