96 GTI vs 98 GTS Speed Difference, Why?

Just picked up a 98 GTS with the 720 engine. Noticed the similar 96 GTI is said to have a top speed of 50 compared to the 45 for the GTS. These have the same hull, engine, jet pump (140mm) and impeller (11/22) Only difference is the GTI has dual carbs (bn38I) vs the GTS single carb (bn40I). Even hp is listed the same at 85hp. What gives the GTI the extra 5mph speed?
 
According to the manuals, the GTI has a 11-24 prop while the GTS has 11-22, everything else is practically identical. I would take book speed numbers with a grain of salt.

Confusing, I see the parts manual for the GTI lists the 271 000 470 for 1996 (same p/n for 98 GTS) with the 11/22 pitch. Did you see it in the service manual?

Seadoosource.com's impeller list is where I initially got the impeller info from.

Yes, at the very end where it lists the technical data for each model. 1775692404039.png
 
I haven't ridden a 717 Carb GTI yet that goes over 46mph on the GPS. Great skis and a lot of fun. My cousin had a GTS which was a very dependable smooth running ski. He said GTS stands for "goes too slow." :D I've restored a lot of Seadoo Jet skis. 717's don't go 50mph unless it is in a smaller 2-seat ski. To run 50mph in a larger 3-seater hull you need the 787.

Spot on. One reason I sold my 99 GTI was because it was too slow and turned like a pregnant whale although rode like a Cadillac. Then I bought a 96 SPX and my mind was blown. Now that's a fun ski.

I like the GS with the 717. A bit more stable than the X4 hulls and still lots of fun. Yep once you ride a hull that handles you don't want anything less. I like the 1996-2002 GTX hulls.

Next on my list is a GTX. The 787 in the XP was another step up from the 717 SPX for me, tons of power to rip you out of the hole.
