Having owned jets, I/O's and vee drives, you will have the most fun in the vee drive hands down.
Some things to consider.. Just comparing it to a jet.
1. You cannot remove the motor, rebuild the drive , throw the motor back in in a weekend, you can with a jet.
2. You simply cannot beach a vee drive.
3. if you find a sand bar with a vee drive, you just spent in excess of $2500
4. Not just anybody can hop in and drive a vee drive. So you are in essence, the designated driver. There are way too many ways to screw up huge in a vee drive.
5. When they break, they break big.
6. Plan on at least 10 times the maintenance.
7. Believe it or not, they are more crude and chunky than they seem. Not a lot of creature comfort.
8. A flatbottom will give you a flat bottom... They ride like crap even in a small chop.
On the positive side, they're great to ski behind and sip fuel when cruising.
