    It's already in there. You didn't read my thread. Mac's ECU is cover up in the plastic case and it mount on top of the battery, look closer you will see it. Thanks

    by owning it, give them support, such a good and reliable product, people need to be open mind to explore. I don't see many Yamaha, Seadoo, Kawasaki can hit to 75+mph, low RPM on GPS with simple and low cost mod, and importantly stable and low gas consumtion by 15-25% less compare other company.

    You are right, the 15X is rock-solid dependable, handles great, gets great gas mileage and fast. What else could you want?

    I was going to buy one [15X] this year but some of my Kids lost their jobs in the Obameconomy and it took a while for them to find new ones.

    I also have had to spend a couple of tons of money on my boat. As of today, it is fixed, runs like a scalded dog [92.4 in the 1/4 mile today], which is not bad for a "Family" boat.

    Well...how about that! I thought you were referring to MACs IC in your first post. Next time I'll super size the pics!

    Great looking ski. Wish I could afford one of those. It even "Looks" fast.
    These things are hitting 75+? Thats plenty fast for the mods listed.
    How does this ski handle off-shore?
