i can help answer your question
first, i sued the learning key for all of maybe 1 hour. after that i put it away. You still dont want to go crazy or WOT until aftert the break-in period, but you can still have more fun with the normal key, then the learning key!
As for breaking the ski wave jumping - i seriously doubt it! I took my ski out last summer during some high winds. i was the ONLY boater out on the water. wave were easily hitting 2-4 feet. The inland lake i was on is about 7 miles long, but is only about 20-30 feet deep on average. That day was the absolute most fun i had on my sea-doo. I would get going about 25-35 mph, and when i hit a wave, i would turn the ski going airborne. If i timed it right, i would come down just below the crest of the next wave. this in turn would cause a tidal wave of water to spray all over me. it was a blast! Almost threw myself off the ski a couple times, but i stayed on.
the following day, the winds had died down quite a bit, but i was back out there making my own waves, and then jumping those. I didnt realize until i was done and ready to head in, that i had an audiance. it seems a couple boats stopped to watch. I am not sure if they watched to learn what NOT to do on a ski, or to see what i could do lol
So will the ski break by jumping waves - HAHA i dont think so. The only thing i can think of, and i only know this by reading the threads on this forum, is that alot of folks think that the engine will over rev when you leave the water, and could cause damage. There is technology in place on the ski to prevent that (clutch)- but that can lead into other issues as well (ceramic washers)
Other more smarter folks can talk about that.
Just have fun, keep safe, and your jet-ski will last you.
