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?
