Compact & fully integrated design
Space-saving
With a design that occupies 60% less space than traditional combustion engines, the X-Series motors provide greater installation flexibility while freeing up valuable onboard space for passengers and equipment.
Lighter weight
The X-Series motors weigh up to 65% less than conventional combustion engines and 30% less than comparable electric inboards. This reduction makes installation easier, enhances performance on the water, and improves overall efficiency for a wide range of vessels.
Hydrogeneration
All X-Series models are equipped with integrated hydrogeneration, enabling the battery to recharge by capturing electricity from water flow while sailing.
Easy to install
Pre-connected internal wiring provides a true plug-and-play setup, making installation straightforward and allowing for immediate use upon delivery.
Easy to maintain
With advanced technology and carefully engineered interfaces, X-Series motors require significantly less maintenance than traditional combustion engines, reducing downtime and ongoing costs.
