2005 PowerQuest 300 Revenge 496 Mag Ho's. Props turn in and most other boats I see turn out, what's the difference, plus the top of my props are level with the bottom of the hull and most others are 4 to 6 inches deeper in the water than mine. The dealer said to keep the drives down and in all the time accept at high speed for the boat to run best. New performance boat owner so all opinions appreciated.

I am new to this also only 4 years now but I would recomend you speek with others with the same set up my boat runs out and I find it works better ,as for your prop depth your x demension is high that is for better top end and keeping the drives tucked in lets you get up with much less effort.

i read somewhere on here that 1 way is for more speed and the other is for better control...but dont remember which is which

Turning in gives you more speed but points the X center point of your boat closer in so you have less handling (especially when docking) turning out usually loses 1-4MPH or so but you pick up a ton of docking capabilities in my experiences.

I was just having this discussion as well, if you compensate for lower transom lift on the props would that work better ?

Spinning in provides better bow lift on a straight vee. Less wet surface. But you have to drive it more to keep it balanced on the keel. Dock manners are bad spinning in. I tried spinning out this weekend and had a very hard time getting on plane versus spinning in. My drives are raised 2".

To test, do you just change props from one side to the other?

If you have Bravo drives, thats all you have to do. Then run the shifters in reverse to go forward. If after testing, you want it to be permanent, just reverse the shift cable locations on the shifter.

I can't speak for all brands, but Fountain used to run them one way for their old "straight" hulls and the opposite way for the newer "stepped" hulls.

I do have a harder time getting on plane turned out.... Takes full tabs and usually around 2500-3000 rpm to lay her down flat. But my boat needs bigger power and is extremely heavy.
