Where can I find a prop nut!?

[Chris Can]

I have a 1981 Yamaha Mariner 8 that runs flawlessly but the last time I took it out, the prop nut came off. Lucky I was not far from the doc and was able to retrieve the propeller. But I lost the nut and pin. I have looked on a million different sites and they all say the part is obsolete and out of stock. I checked with a local boat dealer who told me they couldn't get the part either. The part number is 80545M and boat serial is 677S045247. Any info would be great!!

hardware store get a stainless lock nut and some washers and pin put a washer on then the lock nut put a washer on top may need more until the cotter pin holds everything tight. you want everything to be stainless get a flat lock nut not a nylok the one with the dimple.
