What size prop do i need for omc king cobra 454

[Whiteford2214]

I have 1991 four winns 265 vista with 454 king cobra outdrive. Well somehow I've managed to lose my prop or it was stolen.and I have no idea on what kind of prop it was or size or pitch. I'm selling the boat so I'm just looking for something for cruising maybe pull a tube and not real expensive.any help would be greatly appreciated. Thanks everybody
