Here's Johnny

all good advice but I would go down to the Sonic Owners Forum and post this question.....the 31' owners are great with all their knowlege on props and how the boat reacts to different styles of props.......being a Sonic owner this doesn't sound normal to me.......my 35' gets up on plane real fast with no blowout or spinning.......all I do is put the tabs and drives down and she is up and away........good luck with the new ride, once you get it dialed in you will love it........but I am sure you already do..........and post some pics please.........
