The Hobie Thru Hull Plug is a replacement plug that allows you to thread wires through the hull of your boat to install fishfinders, GPS and more. One plug, nut, and o-ring is included.
I needed a clean through hull access for my power cables connecting my fish finder to the battery inside my kayak. This is a great product and finishes off a clean access point giving your install a professional look.
Great little idem that hide wires
