I have a set of 250 Mercury Pro XS decals I bought for my motor. I got them from DiscontinuedDecals.com. online it showed a bright blue, but when they arrived they were more of a Navy Blue. I haven't even taken the decals out of the packaging (they are for the 2006-2013 year models)
Asking $75. Located in North Fort Worth. Feel free to Call/Text 214-458-0524. Thanks.
