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:
\uff0a Stable cruising even under 400 kg payload conditions
\uff0a Lower power consumption per unit of thrust
\uff0a Reduced structural stress on SUPs, kayaks, and inflatable craft
Lightweight design is not about sacrificing performance \u2014 it is about sustaining it.<\/li>\n<\/ol>\n\n\n\n

- A Power System Built for Long-Term Use<\/strong>
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:
\uff0a Motor efficiency remains consistently above 80%
\uff0a Service life increases from approximately 200 hours (typical brushed systems) to over 1,000 hours
\uff0a 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.<\/li>\n\n\n\n- Safety as a Design Foundation<\/strong>
At IFUNGOO, safety is never treated as an add-on feature.
\uff0a The fin, battery, and wrist remote are all rated IP68 waterproof
\uff0a The floating wrist remote automatically shuts down within 5\u20136 seconds after water immersion
\uff0a 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.<\/li>\n\n\n\n- Modular Construction for Practical Maintenance<\/strong>
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.<\/li>\n<\/ol>\n\n\n\nClosing<\/strong>
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.
