Prop Nut Kits?

[lordgoliath143]

I've got a Merc 30HP 4-stroke (2001) with no prop. I selected the prop I will be adding (Michigan Vortex from iboats)and it comes with a hub kit so I am set as far as that goes.<br /><br />It is my understanding that I'll still need a prop nut, tab washer and cotter pin? I've been looking at the prop nut kits offered here but don't see one that fits my application (not readily anyway) as they all seem to indicate a higher HP rating motor or lower. Can someone help me out with what I'll need?<br /><br />Thanks,<br /><br />James
