The new point of contention. At least we moved beyond Jet vs. Stern, or Mobil 1 vs. MOTUL, conventional vs. synthetic, winterize with antifreeze vs. no antifreeze, or the all time great, fog engines or not during winterizing. I will tell you that the fact is Chaparral makes a quality boat that has superior fit an finish to the Yamaha's. I would never argue that my Yamaha has better fit and finish than a Chap, Four Winns, Cobalt, or a real Sea Rays (Not the jet boats that are really Sea Doos). However, I, like most consumers are forced to balance such things with cost, longevity (as it relates to jet propulsion technology), maintenance, familiarity, and reliability. These are all the reasons I bought my 2nd Yamaha last year.
As for the Rotax.........I am not convinced that this engine is as unreliable as everyone states. Those engines have been in their Sea Doo jetskis forever and I would argue that SeaDoo makes the best skis. However, I do find the rebuild an annoying and expensive task that would somewhat deter me, but not to the degree that most state.
I have seen a lot of folks reason that the price is similar. Based on my research and the answers I got at the boat show, the prices are not similar when you compare Apples to Apples. The Yamaha remains the most cost effective brand in the market and still out sells all other manufactures in the 20 - 24 foot space.
By the way, I love Chaparral and some day will own a Signature 310, but right now, I choose to stick with Yamaha!
