So that Mach Sterndrive prop showed up today. Was 14x24p a standard size? What was the finish like on them? This thing is like a work of art, perfect shape, you could cut yourself on the edges, highly polished etc.... Im wondering if this thing has had a lab job, it looks really sweet for a stock prop. Where they that nice?

Anyways, Im currently running a 23 mirage that I straightened with a BFH and ground the edges. Spinning it about 4700 which is about it on a 7.4, with better condition, less diameter but more pitch and blade Im hoping I can spin it.....

Sounds like that one was worked on, without prop scan you really don't know the true pitch. Of course you can measure the diameter, should be 14.5". Try it and see what you think but you are probably going to be around 4500 or so.

I did measure it, clearly 14" and stamped on the side 14x24

x2 on the test date.
Just checked all 4 of my SternDrivers, they measure exactly 14.5" so your prop has been worked a bit; they did not have fine leading edges and were all satin from the factory. Guy next to me has a few pairs he uses on a 35 Fountain, his also are as I described.
