You would have to drill holes in the OEM one if you need to drill holes in the KFI mount to install your winch. I already went through this because I had a Warn 4000 lb winch that had a bigger mounting pattern than the two winches recommended by Yamaha. If your winch has a Hawse fairlead, I would not recommend the KFI mount because of the cutout on the front of the mount. The Hawse fairlead doesn't cover the entire opening so it doesn't look right.
