The Scotty 170 2.25" Ball Mounting System brings together three purpose-built components to create a stable, fully adjustable mount for 10–12" fish finders and chartplotters. UV-resistant engineering-grade nylon and corrosion-resistant stainless steel hardware stand up to saltwater environments, while the dual 2.25" ball joints deliver 360° of rotation and 180° of tilt at each end for precise screen positioning. The classic Scotty 241 hole pattern on the base means it pairs directly with a wide range of Scotty mounting options.
