Wrong Prop?
 

I ordered a prop from my local marina using my serial numbers and when it came in and i went to change it today it does not look like the one i removed. I have a 1999 182 shabah with the alpha one gen 2 outdrive. The prop on the drive had a bushing in it and the michigan prop I bought slides on the drive shaft, but does not have a bushing. It lines up with the teeth, however there is a gap between the prop and the locking nut, as well as nowhere to place the lock washer (one with 6 teeth), or the locking hub. I am assuming they sent me a prop for a bravo drive, which sucks since I am leaving for the lake tomorrow. Just looking to see if I am correct in my assumptions, or if I am missing something. thanks
