I had the 1989 version of that boat. I was not not into wakeboarding at that time but have always wondered how decent a wake it would put out. Yours looks good for an I/O
MY BOAT IS NOT AN I/O!!!!!!!!!!!!!!!! everyone always says that. its a 21 foot dd spyder skier. everyone always seems to think that they didnt make a direct drive. sorry just figured i had to say something.
