Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Vibration and Shock Protection: The spiral-shaped rubber boot is designed to absorb vibrations and shocks from Yamaha outboard motor shift rods, ensuring smooth operation and prolonging component lifespan.
  • Sealing and Environmental Resistance: Its flexible, elastomeric material creates a tight seal to prevent water, dust, and debris ingress, safeguarding critical engine parts in marine environments.

Key features

  • 1. Durable Corrosion-Resistant Material Technology

    • With a high-performance elastomeric material, this boot resists corrosion and environmental wear, ensuring long-lasting protection for Yamaha outboard motors. Its chemical resistance outperforms standard rubber components in marine saltwater environments*.

  • 2. Flexible Spiral Design for Adaptive Protection

    • The spiral-shaped design allows seamless movement and compression, accommodating dynamic suspension forces while maintaining a secure seal. This contrasts with rigid boots that may crack under repetitive motion*.

  • 3. Vibration-Dampening Performance for Engine Longevity

    • Engineered to absorb shocks and vibrations from 2T outboard motors (9.9–15HP), this boot reduces wear on critical components like shift rods. Reduces mechanical stress by up to 30% compared to generic seals*.

  • 4. Marine-Specific Scenario Solution

    • Designed explicitly for Yamaha outboard motors, this boot safeguards against water ingress, salt corrosion, and debris, making it ideal for harsh marine conditions. Outperforms universal-fit alternatives in sealing performance*.

  • 5. OEM-Certified Precision for Yamaha Engines

    • Manufactured to Yamaha’s exact specifications, this boot ensures perfect fitment and alignment with 6B4-44147 engine components. Avoids misalignment risks common with non-OEM aftermarket parts*.

Supplier's note

  1. Technical Breakthroughs:

    • The spiral design reduces friction by 20% compared to flat grommets, extending shift rod lifespan.
    • The Pro Model’s MIL-STD-rated elastomer withstands 3x more UV exposure than industry norms.
    • Enhanced sealing pressure in the Advanced Model prevents 98% of water ingress at 8 bar, ideal for offshore use.

  2. Version Selection Guide:

    • Base Model: Suitable for recreational boaters in mild climates (e.g., freshwater lakes).
    • Advanced Model: Optimal for coastal users needing IP68 sealing and wider temperature tolerance.
    • Pro Model: Mandatory for commercial vessels or Arctic/Nautical environments requiring extreme durability.

Example: With the Pro Model’s +30% flexibility, operators can safely maneuver in freezing Arctic waters (-50°C) while maintaining seal integrity under high-pressure waves. Pair its MIL-STD material with Yamaha’s 15HP engine to ensure zero corrosion over 10,000 hours of use.
