I Wonder if i could take of the exstension on my spark to check if there is any difference in the maneuverability. But I have some questions, I have Ibr. On standard 2up models there is a little piece of the Ibr attached to the hull(?)(see picture) is this something I'll need? And when I take off the extension what will fill the black corner?(see picture)

The Ibr piece I mentioned is right under the warning decal saying something about reboarding...

I took off my rear deck and all it had was 12 screws. They werent connected to anything but the hull. I don't have IBR though. http://www.seadoospark.org/forum/12...s-add-ons/1154-removed-3up-rear-platform.html

Is the screws holding the exstension to the ski the same as the screws holding the exstension together?

No they are different. I believe it was 12 to remove but probably 8 more to split the 2 pieces in half.

Looks good. After you test post if you noticed a big difference. I didn't notice a whole lot but I like the shorter look.

Where does it bolt to? Aren't there now holes in the back of your ski?

It's 4 bolts under the ski, 2 above the jet nozzle and 3 on each side. And no holes that will take in water:)

Finally tested it!! The first thing I noticed was the stability, I was able to shake it from side to side much easier. About the maneuverability... I didn't notice anything, it's just the same. So now it's back on

from the size, I would have to guess the weight was minimal?
Did you try re boarding in the water? I would assume it would be more difficult.
