Gemeco 2057103 Plastic Hull Spacer for Airmar B619 Transducer

The Gemeco 2057103 is a replacement plastic hull spacer designed specifically for use with Airmar B619 and SS619 tilted element through-hull transducers. This essential installation component ensures proper mounting and secure installation of your marine depth finder transducer.

Key Features:

• Designed for Airmar B619 and SS619 through-hull transducers
• Provides proper spacing between hull nut and hull surface
• Allows for adequate thread engagement in metal hull applications
• Helps distribute load evenly during installation
• Durable plastic construction resists marine environment corrosion

During installation, the spacer slides onto the transducer housing and rests against the washer. It is particularly useful in metal hull applications where additional spacing is needed to achieve proper thread engagement for the hull nut. The spacer should not be used if there is insufficient space to tighten the nut or if it comes within 1/2 inch of the top of the housing. This replacement part ensures your transducer installation meets manufacturer specifications for optimal sonar performance.
