Many things will affect jetting like impellers, timing changes, exhaust changes, elevation changes, After Market F/A's, displacement changes, or even higher compression.
If you're jsut .75mm oversized with reeds You may not even n eed to rejet. Maybe just open the screws a bit more.
If you;re more than 2 1/2 turns out on any screws, go up 1 jet size.

I have a TDR waterpipe, boyeson (sp?) power reeds, R&D grate, port/polish exhaust as well. One of the SeaDoo guys I work with recommended I go up one size in my jets, or uncap the high speed.
