Regal 1900 LSR - 4.3GL with SX drive 190hp running 14.1/4 - 21 prop. <br /><br />I have just brought an O'brien Wake Wizard II and most times with even one child weighing only 4 stone the ring dives under the water. The same happens with no rider or two or three riders. I have tried slowly accelerating or straight to full throttle with a taught rope. The odd times it gets going its fine. <br /><br />Any ideas why this is happening at the moment spent loads of money and the kids have been put right off!.<br /><br />Regards<br /><br />Chris
