E-LINE inboard electric propulsion system

The VETUS E-LINE inboard electric propulsion system delivers quiet, emission-free power for both existing boats replacing their diesel engine and newly built vessels. Compact in design and easy to install, the E-LINE can be mounted directly on an existing motor foundation using its supplied engine brackets and mounts, making repowering straightforward. At the same time, it is equally well-suited for integration in new-build projects, ensuring reliable performance and a full day of silent cruising.

Within the E-LINE range, you can choose between two versions to match your boat and sailing style:

E-LINE AIR – a compact, air-cooled solution ideal for smaller boats up to 8 meters (26 ft).
E-LINE (fresh water or keel cooling system) – a more powerful and efficient system designed for boats up to 11 meters (36 ft).

E-LINE AIR – Compact and air-cooled

Featuring an optimized design with less components, the E-LINE AIR is even more compact and lightweight than a standard liquid-cooled system. Engineered to use natural air as cooling agent, these E-DRIVES reliably dissipate heat without the need of additional cooling equipment.

E-LINE – Powerful liquid-cooled electric propulsion system

The E-LINE range is designed for longer trips and heavier loads, powering boats up to 11 meters (36 ft). Its liquid cooling keeps performance consistent and whisper-quiet, with the choice of fresh water cooling or a closed-circuit keel cooling system for salt or muddy conditions. Delivered plug-and-play with Swap & Go brackets and Active Electronic Braking, the E-LINE ensures smooth, efficient and silent cruising with full control.
