Just bought an 01 Seadoo GTX, will be picking it up next weekend, basically looking for the simplest/cheapest possible way to get 10 - 20 miles out in the gulf of Mexico where gamefish live, the ski will never see speed over 40 again but will never see fresh water again either. Newer skis with 4-stroke engines are heavier than I'd want and the 01 model seems to be the most advanced 2-stroke.
I'd assume the GTX is injecting oil and fuel into the lower chamber of the engine rather than using carbs (ie still using the lower chamber to pump fuel/air mix) whereas something like an Australian 2-stroke or that new E-Tek engine are injecting fuel into the upper chamber after ports are closed, somebody tell me if that's wrong.
I'd also guess that somebody running the thing at 20 - 30 knots might get a bit better mileage/range than the charts indicate; charts indicate a range of around 70 miles on a 15 gallon tank.
The only other 2-stroke vehicles I've owned in past ages were an old Auto-Union DKW S-1000 (car) and a Kawasaki 500 3-cylinder bike. Again a 4-stroke engine on a jet-ski would seem to defeat the purpose.
I'll have lots of dumb questions....
