Cant comment specifically on the Sabre or Margay but all that I have read says that the Fury likes to be run at a lower setting on the jackplate. Also from reading, I dont think many people use any PVS plugs….just not needed. Hopefully somebody with a similar rig can comment for you soon.Jim EbarbMany, LA (Toledo Bend Lake)2004 Cougar/ 225 OptimaxHumminbird Helix 12 Chirp SI on BalzOut Mount at bowLowrance HDS 7 at bowHumminbird Helix 12 Mega SI on Ram Mount at ConsoleLowrance HDS 8 in dash at console
