Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Propeller Protection: The 420D nylon propeller cover safeguards boat propellers from debris, UV damage, and corrosion when the vessel is out of water or in storage.
  • Visibility Enhancement: Integrated flag ensures high visibility during trailering or storage, acting as a safety marker to prevent accidental contact or theft.

Key features

  • 1. 420D Nylon Construction for Enhanced Durability

    • With 420D nylon material, ensure robust protection against corrosion and abrasion in marine environments. This heavy-duty fabric is up to 50% more durable than standard polyester covers*, providing long-lasting performance for frequent use.

  • 2. Integrated Reflective Flag for 360° Visibility

    • The built-in reflective flag enhances visibility, alerting nearby vessels and pedestrians to your boat’s presence. This design offers 360° visibility compared to standard non-flag covers*, ensuring safety during trailering or storage.

  • 3. Secure Fit with Leak-Resistant Design

    • Engineered to fit snugly on propellers, reducing water leakage by up to 40% during transport*. The reinforced seams and tight seal protect against debris and environmental damage, even in rough conditions.

  • 4. All-Environment Adaptability

    • Designed for marine scenarios, this cover safeguards propellers from saltwater corrosion, freshwater debris, and UV exposure. Ideal for both recreational trailering and commercial storage needs, ensuring consistent performance across environments.

  • 5. Marine-Grade Certification Compliance

    • Meets industry standards for marine safety and durability, featuring UV-resistant treatment and corrosion-proof construction. Trust a product rigorously tested to withstand harsh marine conditions.
