Please note revision C of the 2017 ProWatercross rulebook. The changes incorporated will be valid for the remainder of the year including the World Championships being held at Sugden regional park, Naples FL, Nov 2-5.  The rules address requests for allowances in the 4-Stroke Ski Stock and Spark classes.

  • 4-Stroke Ski Stock will now be allowed to use aftermarket handling components, impeller and flame arrestor as identified in sections 24.9 and 24.10 and referenced in rule 26.1.3.  ECU reprogramming will also be allowed as is defined in rule 26.1.5.
  • Spark classes are allowed to run with modified or aftermarket engine access panels as is defined in rule 24.10.9. 

Please note:  Revision B of the 2017 Pro Watercross rulebook.  This revision contains the following changes which apply to the Pro/Am runabout classes:

  • Allowance for modified or aftermarket valve springs and retainers for SeaDoo RXPX and RXTX 300 Models
  • Allowance for modified or aftermarket pulleys and tensioners for the Kawasaki  Ultra 300 and Ultra 310

These changes have been added to the Runabout Box Stock, Runabout Stock and Runabout Limited rules. Sections 34, 35 and 36 respectively.


Pro Watercross is pleased to announce the release of the 2017 Pro Watercross International rulebook. While there are very few changes to existing rules there has been considerable interest in the induction of new models into the 2017 Pro Watercross rulebook. The introduction of the 2017 Kawasaki SXR has provided a new level of excitement for the Ski classes. The Ski GP rules have been adjusted to allow for the new model and the Ski 4-Stroke Stock class has been created specific to the model. ProWatercross has received inquiries regarding the use of the 2017 SXR in the Junior classes. Due to the size and expected speed characteristics of the watercraft there are no allowances for a Junior Ski 4-Stroke Stock class.

Another addition to the 2017 rulebook is the Yamaha WaveRunner EX which will join the Sea-Doo Spark in the IROC classes.

Revisions that were made to the rulebook during the 2016 season have been incorporated into the 2017 rules. The last notable change is that the rules governing the Runabout Open class have been removed as the class has been discontinued in lieu of either the Runabout SuperStock or Runabout GP class.

Please review the 2017 rulebook to see all of the changes and additions and to refresh your knowledge of the rules governing our sport. We encourage you to check the Pro Watercross website periodically throughout the year to verify any revisions that may be made to the rules.

We look forward to seeing you at one of the many 2017 Pro Watercross events.
