IJSBA is posting the compiled list of suggestions submitted for changes to the 2024 IJSBA Competition Rule Book. These suggestions are posted, mostly, exactly as we received them. Some suggestions are for rules that, depending on absence of a language barrier, already exist in the Rule Book. If you do not see your submission, please contact IJSBA immediately. IJSBA will release a recommendation as to the course of action for these suggestions in 48 hours. If you have any questions or comments regarding this group of suggestions, please email email@example.com.
- For ski lites class: you can remove the toolbox/lunchbox from the ski
- For ski lites class: you can remove second throttle spring for easier throttle response
- For ski lites class: you can remove from yamaha superjet 2 stroke original plastic front dash in foot tray
- For ski lites class: you can change the location for fuel tap/crane from outside of the hull to engine room. If it’s in the original place, then you hit your knees on it very often.
- For ski stock class: you can remove toolbox from the hull
- For ski stock class: you can remove second throttle spring for easier throttle response
- For ski stock class: you can use aftermarket lighter or carbon hood/bonnet.
- For all classes: ski or runabout must have metal tow hoop not string or strap
Do NOT Impede Progress of another Racer - Safety Rule
In the drawing here the merge lane corridor is separated by the (Sausage Buoy) and this would be proper set up, but the sausage buoy does not extend this long and is set back further behind the finish line. We are adding a longer sausage buoy (an extra) to extend this corridor this year. The arrows indicate what I enforce and are in a straight line as racers should follow a racing line that is as straight as possible and cannot move into the opposing lane. After the sausage Buoy racing is a straight line to the merge bupy. A Racer may not move into the other lane, inside or outside, push, block, Slow or Impede the progress of another racer, in order to gain an advantage in the safety corridor leading into the merge buoy. These lanes in this safety corridor may not be crossed. Race in straight line towards merge buoy. The racer with the lead going into merge buoy has the advantage. Passing is allowed in a straight line. This rule is in place to minimize merge collisions in a higher probability impact zone. Safety corridor penalties cannot be made up during race. You cannot hit my sausage buoys ( 1 lap penalty) You cannot cross over , swing wide or merge into the other lane, coming off of your final turn on inside split or outside split. (1 lap penalty) Racer will maintain straight line and hold that line through corridor. Impede progress of another racer in these lanes is (1 lap Penalty.)
Rule 1: “ Elite” Age Group Class- IJSBA will recognize a new age group division for Ages 16-17 and this will be called the “Elite” Class. Racers will have the opportunity to compete with the age group of 16-17, in the prescribed classes as recognized by IJSBA. This Elite Age group, will be recognized and awarded at the IJSBA JR. National Championship in 2024 as it was in 2023, and proved to be a successful, high caliber and talented group of 16-17 year old racers. We would like to propose to have the Elite Age group class formally recognized in the Rule Book. This additional class presents a greater opportunity for racers to enter the sport of Jetski Racing at this age group, and not be thrust ahead into novice or amateur classes. Following the age group classes recognized for Junios, this would allow Juniors the opportunity to move along in a natural progression towards amateur without having to make the decision to compete with adults at 15. There is an AGE GAP and For Safety I see the 16-17 class allowing racers the ability to compete and make progress in the age group before moving to true adulthood at the age of 18. Not quite out of the house at 16-17 and not quite an adult or recognized as such until 18. This would also allow racers in this age group to fit into a sweet spot of growing Junior classes including GP ski class and rec lites class and provide additional revenue stream for this Elite age group classes. (10-12, 13-15, 16-17ELITE, novice, amateur, expert, Pro-am, Pro)
- Do not delay aftermarket hull homologation.
- Confirm blow off valve for Runabout Stock classes
- Formally allow a adjustable timing gear on the Kaw. SX-R 1500 stock class. You are allowed to change the timing but you have to press it and on.
4, Finalize policy for existing spray deflector that overhangs the bond rail.
I suggest am Gp to be allowed to have modified motors
There should be credentials to race a GP ski! You have to have x amount of experience on lesser skis
Suggestion: I suggest the following rule change:_In GP class it states you must use an OEM fuel filler and fuel filler hose and it cannot be modified. I propose an allowance to shorten an OEM filler hose if needed. No joining only shortening. I believe this change will have the following positive effect on competition: As it will allow easier fitment of OEM tanks into aftermarket hulls while maintaining all OEM standards regarding construction and materials.
7.18 POST-RACE TECHNICAL INSPECTION 7.18.1 Suggested technical inspection procedure is to impound and inspect the first three watercraft in each class. However, the actual number of watercraft to be impounded will be decided by the Race Director or Technical Director.
7.18 POST-RACE TECHNICAL INSPECTION 7.18.1 A Mandatory technical inspection procedure immediately following the completion of each moto is to impound and inspect the watercraft in each class. All competitors will pilot their watercraft directly to the Tech inspection area directly from the checkered buoys by way of water only, NO EXCEPTIONS. Removing a watercraft from the water prior to tech inspection will result in immediate disqualification. The actual number of watercraft to be impounded following the final moto will be decided by the Race Director or Technical Director.
Suggestion: I suggest the following rule change: Clarification of rule VSK 1.1 about the word stock . I believe this change will have the following positive effect on competition: Prevent fighting about what stock means, since it has different meanings.
Suggestion: I suggest the following rule change: Allowing modified or aftermarket hull and top deck, while maintaining OEM length and width (VSK 2.2). I believe this change will have the following positive effect on competition: Allowing better riding, and turning control for better racing.
Suggestion: I suggest the following rule change: Allowing there to be 2 sets of sponsons, front and rear, as well as clarification about how the dimension limits should be measured (VSK 2.4) . I believe this change will have the following positive effect on competition: Most skis in the class already use 2 sets of sponsons, front and rear, which is a bolt on performance upgrade. It would keep most skis in the class as well as allowing for better turning and more competitive racing.
Suggestion: I suggest the following rule change: Allowing the hulls inner liner or deck to be cut or modified, and allowing removal of foam (VSK 2.12) . I believe this change will have the following positive effect on competition: Allowing the ski to have tray modifications while allow for better riding and turning, which leads to a better and more entertaining race
Suggestion: I suggest the following rule change: Allowing inlet and outlet opening in the hoods to be larger than stock. (VSK 2.13) I believe this change will have the following positive effect on competition: Aftermarket hoods are already allowed in a previous rule . All aftermarket hoods have 2 or more inlet holes allowing more air than stock. Removal of the wording in VSK 2.13 will allow for aftermarket hoods to be used without breaking rules. Using aftermarket hoods replaces the stock hood with a lighter and stronger hood, while allowing the look of the ski to be updated. It also can allow for less water intrusion into the engine bay.
Suggestion: I suggest the following rule change: Allowing the bulkhead to be modified (VSK 2.14). I believe this change will have the following positive effect on competition: Hulls of different years had different driveshaft and pump setups, a common solution to this is using a conversion bearing on the bulkhead to allow for new years parts to be used to older hulls. By allowing bulkhead modification it will allow for older skis to be within the rules if they are using the same parts the newer years skis are using.
Suggestion: I suggest the following rule change: Allowing aftermarket fuel pumps to exceed 4 psi (VSK 4.2) . I believe this change will have the following positive effect on competition: Fuel injection on these skis requires retrofitting parts into the system. Most injection systems require high pressure fuel for the proper flow rate and operation of the injectors. Allowing high pressure fuel systems will help development of new parts for races that will allow for more power out of the motors.
Suggestion: I suggest the following rule change: Allowing original fuel filler to be removed (VSK 4.4) . I believe this change will have the following positive effect on competition: The fuel fillers are old and can crack. Removal does not provide any performance gain to the ski, but allows for easier maintenance for the racers.
Suggestion: I suggest the following rule change: Removal of rule VSK 5.1, VSK 5.2. I believe this change will have the following positive effect on competition: Allow for aftermarket ignition and total loss setups to be used. Allows for better control of the motor and for more power to be generated. The motors are more responsive and allows for faster racing.
Suggestion: I suggest the following rule change: Allowing for flywheel cover modifications (VSK 5.3). I believe this change will have the following positive effect on competition: It does not increase the performance but makes the ski easier to work on if things can be mounted to the flywheel cover. There isn't a lot of room in the skis. But allowing flywheel cover modifications, it allows for better housekeeping in the engine bay
Suggestion: I suggest the following rule change: Allowing for relocation of electrical components (VSK 5.5) . I believe this change will have the following positive effect on competition: Allow for better workability in the engine compartment, It does not add to performance but makes it easier on the rider
Suggestion: I suggest the following rule change: Removal of the limits set on pump length or at least updating them (VSK 6.1). I believe this change will have the following positive effect on competition: The rule is based on the stock 550 pump, while most sksi now use the 750 pump which is larger and can exceed the limits set. The 750 pump allows for better traction and control in the water so there can be tighter and faster turns without the ski sliding.
Suggestion: I suggest the following rule change: Allowing titanium driveshaft, impeller housing, and stator vane assemblies (VSK 6.1). I believe this change will have the following positive effect on competition: Allowing updated materials to be used for higher performance. This can decrease the weight of some components and allow for more power to be generated.
- stock engine ( air filter , ecu reprog only ) and aftermarket pump is my suggestion for 2024. This would be a good chance in any case. Better accessibility, reduced price, equal performance between drivers, less dangerous, pre-access to the PRO GP category.
I would like to suggest a 760 cylinder for the Blasters to even out the playing field against the Seadoo HXs. I believe this will attract more riders that are thinking about coming out to race and keeping the regulars interested in continuing racing.
Suggestion: I suggest the following rule change:_13-15 Stock ‘not to be restricted’ _. I believe this change will have the following positive effect on competition: _With the addition of 13-15 Mod class which has speeds greater then the Stock SXR 1500. I think this change would be a positive part of the progression in increased speeds for all.
Ski 4 stroke lite
Suggestion: I suggest the following rule change: Limited 650, 750 , Mod 800-1100cc classes in X2. All X2 classes to keep 140mm pump size.
I believe this change will have the following positive effect on competition: X2 class has been one of the largest classes the last several years. But because of the rarity of 800cc motors it makes it no longer cost effective. Not one person the last several years has won the X2 class without having an 800+cc motor and spended $12,000+ dollars on a 30+ year old ski. Having 2 classes evens the field and allows more racers to get involved.
X2 class there was an amendment of allowing 4 sponsons but the rule book only says two are allowed.
For the Expert GP category with stock engine and aftermarket pump and veteran category at +40 and not _+35.
