Quick D110 Fiberglass Tunnel

The Quick D110 Fiberglass Tunnel is a purpose-built thruster tunnel designed for marine and small craft installations where bow thrust capability is required. This component serves as the structural conduit through which bow thruster units operate, providing a streamlined passage that minimizes turbulence and maximizes propulsive efficiency. Whether you're installing a new bow thruster system or replacing a damaged tunnel on an existing vessel, this fiberglass construction delivers the durability and precision fit that professional installers and vessel owners demand.

Manufactured from high-quality fiberglass composite, the D110 tunnel measures 1000mm in length with a 110mm internal diameter and 5mm wall thickness—dimensions engineered to accommodate standard bow thruster motor units while maintaining structural rigidity under operational loads. The fiberglass material resists corrosion, osmotic blistering, and galvanic degradation that affect steel or aluminum alternatives in saltwater environments. The 5mm wall thickness provides adequate reinforcement without excessive weight, a critical balance for boats where load distribution affects handling and fuel economy. The tunnel's uniform bore diameter ensures smooth motor mounting and optimal hydrodynamic flow characteristics.

This tunnel is ideal for installers working with Quick brand thruster systems and compatible third-party units requiring a 110mm bore specification. Professional marine technicians appreciate the straightforward installation process and the tunnel's ability to integrate seamlessly with existing hull structures. Before purchase, verify your thruster motor's specifications against the 110mm diameter and ensure the 1-meter length accommodates your vessel's through-hull routing. Proper bedding compound and sealant application during installation ensures a watertight seal and prevents future leakage or structural compromise.
