When ultimate performance meets absolute safety, the boundaries of on-water exploration are pushed further than ever before. With a decade of R&D behind them, IFUNGOO’s Y-Series fins combine aerospace-grade hydrodynamics with precision motor engineering to deliver the best propulsion solutions on the market.
IFUNGOO Fins are compact, lightweight, high-thrust, and easy to install. They meet industry standards and carry multiple proprietary patents and international certifications (CE, FCC, UN38.3, MSDS, RoHS). Manufactured on our own production lines with a monthly capacity exceeding 5,000 units, we also offer OEM and custom-build services.
All models are driven by permanent-magnet brushless motors with field-oriented control (FOC). This provides comprehensive protective functions, industrial-grade durability and an extended service life. The fins have a modular design, with wear-prone parts such as the tail fin and ducted shroud made from carbon-fibre-reinforced nylon. These parts are fully detachable and highly interchangeable, which simplifies maintenance and reduces operating costs.
I. Core Design: The Perfect Balance of Lightweight Build and Potent
Power
Exceptional power doesn’t have to be heavy. Through the precise hydrodynamic design of our shrouds and fins, we minimize drag and increase propulsion efficiency by over 30% compared to conventional models.
Models
Y01 — Flagship: 1.6 kg | 600 W | 13.5 kg thrust — stable cruising at 400 kg payload (suitable for 4–6 people)
Y02 — Elite: 1.1 kg | 450 W | 10.5 kg continuous thrust — optimized for 2–4 people
Y03 — Classic: 1.24 kg | 350 W | 8.3 kg thrust — excellent at 200 kg payload; ideal for solo use
II. Technological Heart: Quiet, Reliable Power
Powertrain — High-efficiency permanent-magnet brushless motors
All models use high-performance brushless motors rated at 3,000 rpm, and motor efficiency of over 80%. Compared with brushed motors, service life increases from roughly 200 hours to over 1,000 hours, and operational noise is significantly reduced.
Smart Control — FOC vector drive
Industrial-grade FOC controllers deliver multi-layer protection: adaptive voltage control for stable thrust; audible/vibration warnings in the even of entanglement and automatic shutdown if entanglement worsens; continuous operation up to 1,000 hours under maximum load.
III. Comprehensive Protection: Your Assurance for Carefree Exploration
Intelligent waterproof safety system
Fin, batteries, and the wrist remote are all IP68 rated. The wrist remote is buoyant and features automatic shutoff 5–6 seconds after immersion to protect the user in the event of a fall.
Emergency switch for assured return
The batteries include a backup emergency switch. If the wrist remote is lost or the remote battery dies, the emergency switch enables the battery to continue powering the unit, allowing a safe return.
Modular, durable construction
The tail and shroud are made of nylon reinforced with carbon/glass-fiber composites. Modular, user-replaceable parts simplify maintenance and reduce lifecycle costs.
IFUNGOO Y-Series is not just a propulsion device — it’s the key to a freer, safer, and more enjoyable life on the water. Thanks to our advanced technology, strict quality control, and user-centric design, we invite adventurers worldwide to experience the future of water propulsion.
