No, just standard X drive with dual water intake. I was so happy with my 26 Stock B1 (17% slip) that I was going to change only if something else was perfect without a lot of work (labbing/drive height etc ....)
I could do better spending time and money with Brett I'm sure, but it's just not a priority for me right now. I also tried a labbed 26 B1, labbed 28 B1, stock 24 B1, Hydromotive 4 blade and the stock Maximus 24.
By far I liked the stock 26 B1 for bow lift and overall boat position along with a good slip number, great cruising speed, and a good RPM for my dyno chart.
