Includes cabelas mounting plate, HB quick connect mount, HB power cord ready to be connected to 12V, HB soft case, and HB ice ducer. All you need to do is pull your 597 of your boat and put it on the quick connect mount. I put about $170 in for all the parts. I’d let it go for 100.
I sold the boat and thus the 597 went with it so the it will just be occupying garage space otherwise.
Sidenote: this is for a 597C, not and 597DI. The DI version requires a different ducer than what I have in this package.
