You might be getting "lift" off the rudder as the hull leans into the turn. In that case its going to take some tweaking to remove. Like either adjusting the stinger or rudder. Are you running the stock prop?

grimracer 40x52/3 metal prop

you will get less cavitation with a 42x55 grimracer prop as well bud its verrrry popular and faster

Another thing you wanna do is move the batteries up. Remove the battery trays completely, and then move your batteries around inside until the center of gravity is 8 3/4" from the transom (rear). This will balance the boat out and you should see less cavitation. Once you've found the center of gravity, place a full length strip of velcro on both the battery and the boat. Hope this helps!

What makes that prop better?

[driftah]

well its a 2 blade vs. a 3 so more top end speed and if you move the batteries up some there is little cavitation happening,oh and have it sharpened and balanced you will love it

Its 2mm larger as well. The blades will dip into the water a little deeper and get a better "bite"
