Foil Drive Fusion (Base Kit)

With the power and runtime of an Efoil, the lightness and adaptability of an Assist, the Fusion earns its name as the perfect blend of both worlds. As its name suggests, the Fusion is a true hybrid electric foil system, bringing together the best of both worlds in one neat, versatile package. Simply mount between nearly ANY hydrofoil board and mast with Foil Drive’s latest snap-on propulsion. An Efoil alternative, the Fusion is the ideal tool for long rides, learners and performance riders alike. Why an alternative? Because the Fusion isn’t limited to just an EFoil like others. By simply switching to a shorter motor cable length, it transforms into an extremely powerful, long-runtime Foil Assist. Maintaining the lightweight, sleek, hydrodynamic form of the Assist range, the Fusion delivers greater power and longer runtime thanks to the Fusion 860 Battery (864 Wh) and 43 volt electronics. Riders can enjoy a sportier feel without compromising on thrust and boost thanks to the NEW FM+650 Battery (650Wh) and early in 2027 the even smaller, FM+430 Battery. The Fusion / MAX+ Gen 2.5 43v battery ecosystem allows a broad range of weight and runtime options that are cross-compatible with the Fusion. The battery is a separate, removable unit with a fully enclosed, single-piece housing and integrated nose cone for maximum durability, a higher water rating, and improved long-term reliability. This rugged, self-contained design also makes swapping, transporting, and protecting your power source effortless.

All of this is packed into a small, diverse system that can be removed at any time, or installed onto a different setup in minutes.

One Tool, Endless Possibilities.

Unlike the other two systems in the Gen2 range, the Fusion doesn’t carry the “Assist” in its name. Thanks to its technical advancements, it stands apart in its own subcategory, Gen2.5.

Who is it for?

The Fusion is for those wanting an adaptable efoil system OR riders wanting more power and ride time!

• Riders seeking an adaptable and powerful Efoil alternative
• Learners who want stability, longer ride times and smoother progression
• Experienced riders who want more power and more runtime
• Anyone who wants a single system that can do everything including Surf, Wing, Downwind, Wake and Flatwater

Wanting to make install a breeze? Foil Drive recommend pairing it with a Foil Drive integrated mast.

Weight and runtime by battery

*Installed weight includes the unit, battery, integrated high-power motor, three-blade hub, props and nose cone (if applicable). Runtimes are Foil Drive’s guide for an 85kg intermediate rider on a 5’0 40L board with an 800–1000cm² wing, in under 5 knots of wind. Yours will vary with weight, skill, kit and conditions.

Fusion needs the FM+ Battery Adaptor for FM+ batteries. It is included with new Fusion kits.

Good to know

• New Fusion kits include the FM+ Battery Adaptor, so the lighter FM+ 650 fits as well as the Fusion 860.
• A free update in the Foil Drive app adds around 10% more power and thrust.
• Motor pods are no longer in the base kit. Choose a retro-fit motor kit (pod included) or the integrated mast motor.
• The integrated mast motor needs a Foil Drive compatible integrated mast, sold separately.
