I recently purchased two skis, a 2003 stx 1100di and an stx 12f. I read quite a bit about both skis before I went for the test ride and purchase. I love both skis, but question the difference in performance.

The 2-cycle 1100 di outperforms the 4 stroke 12 F in every area...holeshot, acceleration, throttle response, and top speed. Is this normal?

I'm satisfied with the performance of both skis ( I recognized the difference before purchasing) but I'm suprised at the difference. I just want to make sure I'm not missing some perfomance on the 12F without correcting it.

Thanks to all on the forum...I've learned a lot from you guys already!
