Up for sale is a genuine Tides Marine SureSeal drip-free marine propeller shaft seal assembly kit (Part Numbers: HS-2500-2625 / 1983-SF3). This system features a high-performance blue Venair silicone articulating hose paired with a self-aligning fiber-reinforced composite seal housing, offering a reliable alternative to traditional, high-maintenance stuffing boxes. This design provides a watertight, drip-free barrier between your rotating propeller shaft and stationary stern tube, drastically reducing water ingress and keeping your bilge completely dry. The integrated articulating hose allows the housing to self-adjust and absorb engine movement, axial shaft vibration, and hull flexing over rough water, protecting your shaft from the friction and premature wear typically caused by traditional flax packing materials.

Key Features

Drip-Free Mechanical Interface: Provides a highly reliable watertight barrier that entirely replaces leaking, packed gland configurations for a cleaner, safer bilge environment.
Articulating Blue Silicone Hose: Features a premium, multi-ply Venair silicone hose engineered to flex and absorb severe engine movement and shaft vibrations without compromising seal integrity.
Self-Aligning Architecture: Fiber-reinforced composite housing naturally tracks the movement of the propeller shaft to prevent binding and ensure constant face-to-seal contact.
Authentic Maritime Legacy: Manufactured under strict Tides Marine standards, trusted worldwide by pleasure craft owners and commercial maritime operators for dependable underwater gear performance.

Critical Installation & Maintenance Notes

Verify Shaft Fitment: Prior to installation, carefully check your propeller shaft's outer diameter, the inner diameter of your stern tube, and your vessel’s available axial clearance to confirm strict technical compatibility with part number HS-2500-2625.
Water Feed Inspection: Ensure that the cooling and lubricating water supply channels are entirely free of grit, sand, or marine growth before completing assembly. Adequate water flow across the face interfaces is mandatory to prevent dry-running and premature elastomer degradation.
Service Life Scheduling: To ensure the ongoing safety and seaworthiness of your vessel, it is highly recommended to perform a comprehensive physical inspection of the sealing faces during every routine haul-out or dry-dock maintenance cycle.

Please confirm your specific marine propulsion blueprint configurations or original equipment tags match part number HS-2500-2625 before completing your purchase. Feel free to send a message if you have any questions!
