Maybe i'm trying to make the boat do something it isn't designed to do, i'm going to adjust the trim and see what happens. I'm sure that it being 23ft instead of 21ft also makes a difference on turning radius.
Thanks for the input everyone.

I'd still add weight to the back of the boat so the prop is deeper in the water.
If you are trying to throw people off the tube, look for some pulling techniques instead of speed.2006 Supra 24SSV

Definitely sounds like prop cavitation to me. When you load a prop wrong or too much they tend to do that. Essentially drops the pressure on the back side so much the water boils, creating pocket of air. Pretty cool physics behind it.2007 LSV

A few things to consider when pulling the dreaded tube. First of all I hope you don't have it hooked to the the tower, way too much load and could damage things. Second of all, if you have it hooked to the ski pylon like most everyone, that's still elevated enough that when you make a sharp turn the drag from the tube will actually pull (roll) the boat over more thus exposing your prop to a greater chance of cavitation.
Also, as far as tube pulling technique. When you pull from the ski pylon, it's a lot more difficult to whip the tube around because when you turn, the boat is almost pivoting around the pylon (just forward of it) and you lose that tail whipping movement that most of us are used to on conventional ski boats. If you have a transom attach point, you may try hooking a tube there, but your riders will have to deal with more spray generated from rope splash.2008 Mobius LSV

While it rarely happens given the "perfect storm" should a wave hit your tube just right and take it under while you are more focused on fallen riders than the tube the amount of drag that thing creates is an attention getter! That is when towers get damaged. And you can pull a tube for years without ever submerging it but that one time it happens you will be glad you didn't attach it to your tower.-Jake

I've often wondered this myself. If you wake board with a pretty big wakeboarder who knows how to build a good progressive edge and a lot of line tension it can roll the boat over too. Happens all the time on our boat, I can't see pulling a tuber applying any more stress than a 200 lb+ man edging hard...David

Like jake said, if that tube gets under the water, that pressure far exceeds a big wakeboarder. That tube won't let go of the rope either.'08 Mobius LSV, Mods- 1100 lb Rear Sacs, IBS Sac, Center 400 Sac, Dedicated thru-hull intakes and pumps per sac, SeaDek One Piece Mica over Black Roo, EZ Net Cargo Nets, Swivel Drivers Seat, Hot Water Shower, Hinged Wind Block, Bow Cushion Adapter Plate for Drink Holders Access, etc, etc.
