Lil brother has a 18hp on a 16x36 duck skiff and he can't turn the 9x6 and 9x5 so he's running a 9x4 and gets like 18mph with him, battery and lil over 6 gallon of gas. When he puts the bigger props on they slow him down a lot and also suck in the mud but his 9x4 seems to go good in both mud and speed.

I'm running a modified 9x4 on my 20hp and she'll tote a decent load. Jumps in plane in about a boat length too. I'd say try at least that.

Go devil says 9x6 on their 25 Kohler long tails. My wore out 9x6 turns 3440 rpm. Tried a used in very good shape 9x7 BPS Tiger but couldn't get the rpm I wanted. Dropped to 3000 at WOT with me, dog and my duck gear. Same speed by GPS but the engine sounds like it's lugged down.

What kind of shape is your 9x6 in? I need another prop!
