Also posted this on the Advantage page but no response. Let me know what you think. Trying to get a friends 30' Advantage dialed in. It has 2 steps, twin v12 Ilmors 550HP each, teage drives. Boat runs great but wicked chine walk after about 78mph. Fasted I have hit with it was 83, seems to be a sweet spot on the trim were the chine walk is not as bad. Should the Drives be rotating in or out? Should the drive alignment be strait, toed in or out? Probably going to be trial and error but would like to get some feedback.

Boat actually has 3 steps. Props are rotating in and drives are toed out a quarter inch.

Wow, not one reply. This used to be the goto place. I guess all the nonsense ran everyone off.

I'm no help, but V12's or V10's. The only Advantage that I have been in was a handful over 70, twin 27. It was more stable with extension boxes though. Maybe try drive spacers.

Yes, v10's. Going to check the drive depth next. It also has a notch in the transom.

Miss typed, actually has V10 Viper motors.

Jeff shoot me a PM so I can get you my #
