Prop ID / Where?

[gearhead]

I have looked at every place I can think of and can find no diameter or pitch markings on my prop. The only number is "W543". Any idea what that means? How can I properly (no pun intended) measure my prop?<br /><br />Thanks

Re: Prop ID / Where?

On my Evinrude, and I believe most others, it's marked on the inner hub right behind the washer/crown nut that holds the prop onto the spline.<br /><br />You should be able to read it without taking off the nut/washer however. It'll be like 13 3/4 X 15
