Switching from Aluminum to Stainless Steel Prop

[T-Bone]

I have a 25 yamaha on a 1546 express (.100 guage) with a 9 7/8 X 14F aluminum prop that has seen much better days. It's dinged up and out of shape. Just wondering if you guys that run stainless props on these smaller outboards stay with the same size prop when switching from aluminum to stainless. I like the way my current setup runs, just looking for some advice. Thanks.
