At EFS, we hold a high bar for new products. Every addition to our lineup must deliver real, measurable value to the rider. The Vortec props lineup clears that bar.
Introducing the Vortec Sifly1 Propeller for Sifly Boards – EfoilSolutions' most refined propeller to date. Engineered for the everyday rider who demands more from every session.
The prop will fit within the shroud, but it will ship to you with a custom made MJF Nylon 12 cone that is designed for maximum riding speed and efficiency. (ride without the shoud AT YOUR OWN RISK)
Pound for pound, the Vortec Sifly1 provides efficiencies even better than its twin brother — the Vortec FB2 for Fliteboard.
EFFICIENCY
Independent testing confirms the Vortec delivers more than 25% reduction in required power to achieve the same speed as the stock propeller — consistently across the full operating range.
BATTERY & RANGE
More efficiency means more ride time. Expect lower battery consumption at cruising speed and longer sessions at comparable speeds — without sacrificing performance.
SPEED & POWER
The Vortec Sifly1 was clocked at 31MPH (compared to the stock prop at 28MPH, on same day and settings).
In addition, the same power input now takes you further and faster. The Vortec converts energy more effectively across the entire speed range, giving you a noticeable edge on every ride.
NOISE, BALANCE & FEEL
Smooth. Quiet. Responsive. The Vortec Sifly1 was designed to be a joy to ride — refined acceleration, minimal vibration, and a composed feel that inspires confidence at any speed.
Key Benefits: More than 25% power reduction vs. stock (same speed), lower battery draw, longer ride time, higher speed per watt, consistent gains across the operating range, low noise, smooth acceleration.
