Max Power GRP thruster tunnels are built for professional use where installation accuracy and long-term reliability are essential. This Ø125mm x 4mm tunnel in 1250mm length is ideal for hulls requiring extended tunnel penetration or specific thruster positioning.

Manufactured from fully isophthalic resin with a pre-gel coated internal surface, this tunnel ensures a smooth inner finish and strong resistance to marine conditions. The tunnel can be trimmed or drilled during installation thanks to the additional matt coat applied before filament winding, helping prevent internal gel coat damage.
