191 Fs Cavitation When Pulling Wakeboarder

[mjsurfsrodanthe]

I have a 2005 191 F?S with a 150 Yamaha 4-Stroke with a 4-blade prop (after complaining about cavitation to my dealer). It's really strange--when not pulling someone behind the boat, I can make extremly sharp turns going about 45 MPH. However, if I am pulling someone, the motor will cavitate extremely easily. If anyone has a fix, please help...

Someone earlier mentioned an "anti-cavitation plate." What is that, and how do I adjust it?

Thanks

i have a 2004 f/s with a suzuki 140 four stroke. the same thing happens with mine as well as any outboard that you try and make sharp turns with. the prop is entering the wash line and cavitation with occur. happens on my bass boat as well. all you can do is either trim down, slow down, or make wider turns.
i just found this web site so please excuse the late reply

Though not always preventable when making hard turns at speed... You may want to try this first and be mindful of your engine trim when doing such
