GRP (Fibreglass) Thruster Tunnel Ø125mm – Length 750mm

The Max Power GRP tunnel Ø125x4mm in 750mm length is a premium solution for tunnel thruster installations where marine-grade strength and clean fitting are required. Built from fully isophthalic resin and finished with a pre-gel coated internal surface, it delivers long-term resistance in harsh marine environments.

The tunnel’s internal gel coat is protected during the installation process thanks to Max Power’s manufacturing method using an additional matt first coat before filament winding. This makes cutting, trimming and drilling safer and helps achieve a neat professional result.
