I have a brand new furuno B-258 bronze T/H never installed with the high speed block and all hardware that came with it. I have had this for a year or so and changed gears a bit and going with another set up. The Faring block has a little crack from being dropped. The crack is on the very end of the block so no bid deal. Comes with the 10 pin connector but can be changed to whatever you need.

$450 +shipping obo SOLD!!
