Boat: 2011 Sailfish 2360 Pilot House with twin Yamaha 150's
Installed props: 15 P x 14 1/2. These props are fast and responsive but I tried to go tubing and it was irritating how bad they were ventilating where I would have to slow done to get them to bite again.
I do a lot of offshore fishing and the boat is new to me. I don't want to be stuck in a sea condition where these props wont respond.
I have a set of 17 P x 15 1/4 that were spares from my last boat. I am not sure how will they do, but they are free to me.
I would like some input of similar boats from others here if possible.
Thank you.

Hey fishnfool what size and pitch are you running on yours? I have 150's on my 2008 2660. I'm running 19 x 13 1/4 Reliance now and would like to get away from the cavitation problem also. Thanks.

I have the same props as you which I run most of the time because the are more economical and Mt top speed is better. Interestingly I don't have any ventilation problems. My 4 blades are Rev 4s 17 p labbed with some cup added which makes them closer to 18 p. I really like how they perform from the standpoint of lifting the stern, boat seems to ride higher out of the water, and it handles like it's on rails - very responsive. HOWEVER, it's too much prop, I'm not getting the RPMs I would like. What I think would be the better spec is a 15p in a Rev 4, they are big props.

Old forum member cowdogs ran 15p Rev 4s and said he really like them and they greatly improved the vent issues. Forum member fritz is running a set of Rubex Solas 4 blades on his 270cc and he said he loves them too. He has 200 Yammies.

Update: I emailed Ken at Prop Gods and he advised me to check the "Toe" measurements of the outboards and recommended I "Toe Out" to 3/4-inch so my props discharge face towards each other. My motors were "Toe In" at 1.0-inches with props facing away from each other. I made the adjustment and my ventilation issues have gone away. Currently running: 3300 RPM: 15 MPH 4000 RPM: 26 MPH 4700 RPM: 32 MPH 5700 RPM: 38 MPH

Yet another good news story from Ken at Prop Gods. I've never needed his services, but have heard of him multiple times and he seems to be legendary. A good resource like that is invaluable. I never would have even thought to check or change the toe measurement on a used boat, assuming it was set up correctly from the initial installation and leave it be.
Is your terminology correct as to the orientation of "toe IN" versus "toe OUT"? I would logically consider thrust facing each other as a "toe IN" configuration but your description seems to be just the opposite. Maybe I'm just wrong on the orientation of the toe...is it relative to the thrust direction or the forward direction of the boat? Asking because I want to learn!

I always recommend Ken and reming870's story is another reason to recommend him. On my last boat Ken talked me out of buying a new prop because he didn't want me to spend $450 for a prop that would give me less than 1 MPH higher WOT and less MPG.

Stand behind your motors and face forward at your motors. Look at your feet. Toes out puts the props (your heels) facing each other. I believe this is the correct terminology.
