I agree with Ray W that the belching is caused from the hiatal hernia. Your stomach has squeezed through the sphinter and this is allowing the air to pass easily into the stomach. I can tell my belching builds with changes in position like from lying to standing and such. The stomach is never fully closed with a hiatal hernia.
1 Half the weight of a normal Jet Ski. 2  Made of Ploy-tec instead of fiberglass which makes it more durable. 3  Uses a Third of the gas that a normal Jet Ski uses. 4  Cost around $25 to fill up(depending on gas prices) where a normal Jet Ski Cost about $75 to fill up.
It depends on the quality of the ski before you buy it. Last year I bought 2 96 Seadoo GTXs for $2500 with a trailer and they were in good condition. So far, considering minor repairs, gas, replacing lost keys, and a few other things, they've cost about $150 for each trip out plus probably a couple hours worth of work.
