For electric outboard motors, waterproof performance is one of the top concerns for users. Constant exposure to water may cause water ingress and circuit damage. As an electric outboard motor designed for leisure boating and fishing, the Fuber G1.5 not only resists water intrusion but also relies on water for heat dissipation. Its advanced sealing and protection structure delivers outstanding waterproof reliability in daily use.

1. Core Design: Water-friendly Operating Principle

Traditional fuel outboards are vulnerable to water, which easily leads to engine shutdown, rusting and circuit failure. The Fuber G1.5 adopts a completely different design concept.

Underwater direct drive & water cooling system: The motor and propeller are fully assembled underwater. The unit works submerged and dissipates heat directly via surrounding water, making water an essential working medium.

Leak-free magnetic coupling sealing: Magnetic coupling transmission replaces traditional wearable dynamic sealing with stable static sealing, fundamentally eliminating water seepage even under long-term submersion.

Deep-sea grade sealing test: The sealing assembly passes ultra-high pressure test equivalent to 11,000 meters deep sea, fully meeting all surface water application demands.

High-level overall protection: Key electronic cabins, controllers and connectors reach IP67/IP68 waterproof rating, resisting splash water, rain and heavy wave impact effectively.

2. Waterproof Zones & Usage Notes

✅ Fully waterproof areas for permanent submersion

Underwater motor compartment and propeller: Designed with integrated waterproof and heat dissipation structure for continuous underwater operation.

Drive shaft and sealing components: Magnetic coupling and deep-sea sealing ensure zero leakage and water ingress risk.

7075 aerospace aluminum hull: Hard anodization plus triple anti-corrosion coating delivers excellent seawater corrosion and rust resistance.

⚠️ Non-submersible areas requiring splash protection

Top battery pack: Rated IP67 against splash and temporary shallow immersion. Avoid permanent underwater soaking despite safe use in rainy and choppy water conditions.

Control handle and wiring connectors: Dustproof and splashproof for normal water spray and rainfall, prolonged submersion is prohibited.

3. Practical Performance in Complex Water Conditions

Sailing in rainy days: Fully applicable. All electronic parts stay safe under rainfall with normal navigation guaranteed.

Heavy wave impact & shallow water cruising: IP67 protection copes well with splashing waves. Brief full submersion will not cause equipment damage.

Accidental capsizing with temporary immersion: Underwater parts remain intact. Battery and control units can recover normally after being dried within 1 to 2 minutes of water exposure. Do not leave submerged for a long time.

Long-term mooring: Submerged motor and propeller can stay in water safely. Remove the battery for storage to avoid shortened service life caused by humid environment.

4. Waterproof Advantage Comparison with Fuel Outboards

5. Daily Maintenance Tips to Extend Waterproof Lifespan

Avoid long-term battery submersion. Remove battery and store in dry ventilated area after use.

Inspect sealing parts regularly. Clean sediment and impurities around propeller and sealing surface after each voyage.

Rinse with fresh water after seawater operation to eliminate salt erosion, then dry thoroughly before storage.

The Fuber G1.5 electric outboard motor features inherent excellent waterproof capability. Equipped with water cooling system, leakproof magnetic sealing and high-grade protection, it works reliably in rainy weather, rough waves and temporary immersion. Only battery and control sections shall be kept away from prolonged underwater soaking. It serves as a durable and trustworthy power choice for fishing and short-distance leisure cruising.
