Stainless Steel Thru-Hull for ForwardScan – B&G

This B&G Stainless Steel Thru-Hull Kit includes a heavy-duty stainless steel sleeve and a watertight sealing plug, specifically designed to accommodate the ForwardScan transducer. It allows you to prepare the hull in advance for a future forward sonar installation, without fitting the transducer immediately.

Thanks to its self-sealing valve, the transducer can be inserted or removed without needing to haul the boat out of the water. The included plug ensures complete watertightness when no transducer is installed.

Compatible with hulls up to 29 mm thick at 12°, or 19 mm at 20°, this sleeve integrates easily on most boats. It’s the ideal solution for shipyards or boat owners planning ahead for future marine electronics installations—particularly in the field of marine electronics.
