alluminum to stainless

[village]

I have an aluminum 10 3/8 x 13 three blade prop on my boat, hole shot ,WOT and performance is good. I am thinking about going to SS. What size would be comparable in a stainless 3 blade?

If you make the change please post your results.I'm having trouble getting my Scout 160 with F60 Yamaha prop.'d correctly.
Original prop was alum.10.3/8x12. Under-propped,motor would over-rev.@WOT.
(Rec. RPM @ WOT 6100)
After receiving several recommendations to go to a 10.3/8x13" prop I bought
10.5x13 S.S.(closest size I could find in S.S.) this is to much prop and will only allow Rpm @ wot to reach 5100.
I need something between the two.Please let me know how it works out.
I do agree,your going to want less prop then you have now in alum.

Thanks,
