Why Experienced Water Users Are Choosing Lighter, Smarter Electric Fins

In water propulsion, real performance is rarely defined by a single specification.
What truly matters is the long-term balance between weight, efficiency, safety, and reliability.
This principle has guided IFUNGOO’s decade-long development of the Y-Series Electric Fin.

1. Lightweight Design That Delivers Real Efficiency
   Many conventional propulsion systems increase power output to gain thrust, often at the cost of higher drag, greater energy consumption, and reduced long-term durability.
   IFUNGOO takes a different approach.
   Through system-level hydrodynamic analysis, the shroud geometry, fin angles, and underwater profile of the Y-Series have been repeatedly optimized. Under real load conditions, propulsion efficiency improves by over 30% compared to conventional designs operating at similar power levels.
   In practice, this means:
   ＊ Stable cruising even under 400 kg payload conditions
   ＊ Lower power consumption per unit of thrust
   ＊ Reduced structural stress on SUPs, kayaks, and inflatable craft
   Lightweight design is not about sacrificing performance — it is about sustaining it.

1. A Power System Built for Long-Term Use
   All Y-Series Electric Fins are driven by permanent-magnet brushless motors combined with industrial-grade FOC control.
   This configuration reflects a focus on durability and operational stability over short-term specifications.
   Within the same power class:
   ＊ Motor efficiency remains consistently above 80%
   ＊ Service life increases from approximately 200 hours (typical brushed systems) to over 1,000 hours
   ＊ Operating noise is significantly reduced, improving long-duration cruising comfort
   In real-world environments with weeds, fishing lines, or debris, the FOC system provides layered protection. Light entanglement triggers vibration or audible alerts, while severe resistance results in automatic shutdown to protect both motor and battery.
2. Safety as a Design Foundation
   At IFUNGOO, safety is never treated as an add-on feature.
   ＊ The fin, battery, and wrist remote are all rated IP68 waterproof
   ＊ The floating wrist remote automatically shuts down within 5–6 seconds after water immersion
   ＊ A built-in emergency switch on the battery allows continued operation if the remote is lost or depleted
   These safeguards are the result of extensive real-world usage feedback, not theoretical assumptions.
3. Modular Construction for Practical Maintenance
   The Y-Series features a modular architecture, allowing wear-prone components such as the tail fin and ducted shroud to be easily replaced.
   Carbon- and glass-fiber-reinforced nylon composites ensure durability while maintaining corrosion resistance and long-term structural stability.
   For individual users, this means confidence on the water.
   For distributors and operators, it translates into lower maintenance costs and reduced after-sales burden.

Closing
The IFUNGOO Y-Series Electric Fin is not designed to impress on paper.
It is designed to perform reliably, consistently, and efficiently on the water.
Once launched, the difference becomes clear.
