Shawn,
I was looking at their website. I don't see any wording that the motors are New or Used, it says Current Year. I would contact Mercury Marine and find out if the motors from Celebes Marine are factory new AND covered under warranty from Mercury Marine. Can't hurt to ask. I checked on my motor, 225XL Pro XS, $8037. That would be a steal for a brand new motor.
EDIT: Don't bother, it's a scam.
