I've got a 2005 XLV and when I am at a decent speed, say around 25mph or above and try and make a "fairly" sharp turn, I can hear the prop start to slip(for lack of better words) in the water and the engine rpms spike momentarily. Is this a design issue with my boat?

I've noticed this doesn't happen with my friends Tige and his turns very sharp compared to mine. His is a 21" boat, I wonder if the shorter boat makes it turn that much better.

Ideas?
