The Stern Saver is the world’s first glue-on high density polyethylene transducer mounting block. Made from genuine King Starboard. Swap transducers without putting unwanted holes in your boat below the water line. It’s also a great mount for switches, fuel separators, livewell and bilge pumps and more! Great for larger transducers and side imaging transducers and 50% stronger bond than the Mini Stern Saver. Installation kit included with each Stern Saver. Available in four colors to best match your boat, Black, Bright White, Gray, and Ivory. 100% Made in the USA.
