Need some help folks. I have a 1986 OMC sterndrive 2.5 L. I'm having a new prop being shipped to me Friday. I'd like to go out on the lake this Friday. However, I lost my prop nut. The local boat shops give me the evil eye/you are dumb look each time I visit there. Trying to figure out the sizing information of my prop nut so I can go in armed with the correct information. It there an easy way to relay this information to them? It seems like anytime I go in there talking about my 86 omc they always say they don't have anything. Or do new propellers typically come with prop nuts? Appreciate any help.
