So I did a little research and found that these two jet skis which, as far as I can tell, are the closest to the SeaDoo Spark in terms of price. Having said that, both of the rivals to the Spark are still a good $3,000 more than the Spark.
2011 Kawasaki Jet Ski 800 SX-R
MSRP: $7,899
Riding Position: Standing
Displacement: 781cc
Engine Type: Two-cylinder with crankcase reed valve induction
Stroke: 2-stroke
Dimensions: L-90.6", W-28.7", H-28.9"
2011 Yamaha Waverunner Super Jet
MSRP: $7,899
Riding Position: Standing
Displacement: 701cc
Engine Type: 2-cylinder
Stroke: 2-stroke
Dimensions: L-88.2", W-26.8", H-26"
2014 SeaDoo Spark
MSRP: $4,999
Riding Position: Sit-down
Displacement: 899cc
Engine Type: Rotax 900 ACE
Stroke: 4-stroke
Dimensions: L-110", W-46", H-44"
Ultimately, the SeaDoo Spark seems to win on every metric. It is $3,000 cheaper than the Kawasaki and the Yamaha. It's higher displacement means that it is the most powerful of the bunch, and it is also the only one to have space for more than one person. Finally, the Spark comes with some extra touches that the others don't. The Spark has a front splash deflector, can go in reverse, and comes with a ski tow eye. The cherry on top is that the Spark comes in a myriad of colors compared to the Kawasaki which comes in only black or white, and the Yamaha that only comes in blue.
If this doesn't convince you that the Spark is the best deal, I don't know what will.
