Quintrex Large Style Transom Drain Bung & Base

The Quintrex Large Style Transom Drain Bung & Base is a high-quality, marine-grade solution designed to seal and drain the transom area of compatible Quintrex boats and Telwater-built hulls. This combined bung and base system simplifies transom maintenance by offering a complete assembly engineered for secure installation and easy operation.

Manufactured from durable materials, the bung is molded from flexible EPDM rubber while the base features corrosion-resistant plastic components. Together, they form a reliable barrier against water ingress during navigation and trailer transport, yet allow fast and controlled drainage when necessary. The turnkey assembly reduces installer error and ensures a proper fit every time.

Installation of the bung and base system is straightforward and requires no special tools. The base mounts flush into the transom’s drain boss and secures with tighten-down fittings. The rubber bung is then inserted into the base and pushed in to form a tight seal. To drain water, a simple pull on the bung allows it to release and maintain the assembly’s position. Removal and reinstallation are fast and intuitive.

Designed for longevity, the EPDM rubber bung remains flexible even in harsh UV and saltwater conditions, providing dependable sealing across seasons. The base resists cracking and warping under exposure or temperature fluctuations. This combination delivers a durable solution that remains functional even during trailer launching, rough sea conditions, or frequent cleaning.

The bung’s slightly concave top allows water to pool slightly over the plug, enabling small amounts of bleed-off and cleaning fluid flow during in-season care. When travelling or moored, the bung holds tight to prevent leakage from wake, waves, or trailer vibration. This dual-function makes the bung and base system practical and versatile.

Maintaining the bung and base is simple: rinse with fresh water to remove salt and debris, check for softening or cracking, and replace if necessary. The replacement process is minimal and can be done in under five minutes, thanks to the modular design.

The Quintrex Large Style Transom Drain Bung & Base is an economical yet effective upgrade or replacement part for boat owners who value hull integrity and ease of maintenance. It eliminates the risk of water ingress and simplifies routine cleaning and storage.

Ideal for both recreational boaters and commercial users, this bung and base kit ensures peace of mind whether you’re cruising, fishing, or trailering your vessel. Its solid performance, user-friendly design, and marine resilience make it an essential transom component.
