Have a 32 YF with twin 350's.... Any advice on different props and the results speed and fuel economy??? Also will having them cupped help me in either of those categories???

I have a powertech 4 blade from my 350 that you are welcome to try. You would need to get the other counter rotating prop.

Cupping those propellers made all the difference in the world to me. I have a thread with some performance numbers posted under the 32 section. Cupped Yam 23's are what I ended up running.

Speed and fuel economy are not going to be changed much but the boat will hook up much better after they are cupped.

Did you change the pitch at all???? What should it cost to have the props cupped and what is the time frame to complete this normally????

I would go ahead and have them balanced, trued and cupped. Cost about 400 bucks for two wheels and took about a week.

I did not chancge the pitch as cupping is going to bring the RPMS down a little bc you are reducing your slip making the propeller harder to move through the water.
