GRP (Fibreglass) Thruster Tunnel Ø185mm – Length 2500mm

The Max Power GRP (Fibreglass) Thruster Tunnel Ø185mm – Length 2500mm is engineered for strong tunnel thruster installations where extra tunnel reach is required through wider hull structures. It delivers a clean professional finish, excellent rigidity, and long-term resistance in harsh marine environments.

Manufactured with fully isophthalic resin and a pre-gel coated internal surface, this tunnel offers a smooth internal coating that improves flow and helps support optimal thruster efficiency. The tunnel can be trimmed, drilled, and prepared during installation with reduced risk of inner gel coat damage thanks to the additional matt coat applied before filament winding.
