    1. Create a Vintage Ski rule which limits displacement to 550cc.

    2.Create a Vintage Ski rule which prohibits the use of a sponson towards the front of the PWC.

    3.Allow aftermarket charger impellers in Runabout Stock Class for specific brands only (Sea-Doo).

    4.Restrict backdating provisions on OEM parts to distinguish between normally aspirated and forced induction parts to prevent the use of normally aspirated parts on Stock Class watercraft that are equipped with superchargers (or turbochargers).

    5.Allow some exhaust modifications in Runabout Limited

    13.Require that Sport Class watercraft competing under GP Rules to be restricted to a single exhaust chamber.

    14.Increase GP Ski displacement to 1640cc for Ski PWC equipped with normally aspirated four stroke engines.

    15.Allow Trim Tabs to be cut or removed.

    16.Allow OEM fuel pump to be modified or aftermarket in Runabout Limited Class.

    17.Allow AFR gauge to be used in all classes (where not currently allowed).

    18.Allow rear through hull exhaust relocation in Runabout Stock Class.

    24.Prohibiting any competitor with three world titles from competing in any Amateur Class.

    28.Change maximum Runabout displacement to 2000cc maximum by removing the limitation of OEM displacement plus 1mm overbore on all cylinders.

    IMPORTANT: If you made a suggestion for a rule change and do not see it in this list, please contact IJSBA immediately by emailing It may be that your suggestion was rolled into a similar suggestion and the differences will be discussed during voting. It could be that after reading your suggestion, it was determined that your suggestion was already covered by an existing rule. It could be we just didnít get your email. Either way, let us know.

    The IJSBA Managing Director will release a list of recommended courses of action on, or by December 23 (original target date has been extended due to the submission deadline being extended). It is very important that you send in comments to these suggestions within the next 5 days so they can be reviewed and a response included in the Managing Directorís recommendations.

    #3- REALLY??????????
    With the changes they have listed and the ones already in place for stock and limited, Stock is no where near stock and Limited is a step away from open just with a stock hull.

    Yeah... Limited would be closer to superstock now with stock compression. It will be interesting to see what passes the vote.

    #3 is fucking stupid.... you won a world championship... are you really trying to puppy kick the entire field now? at that point you might as well remove the seadoo from stock class all together because running the impeller is going to require mods that would bump you into limited class

    #'s 5,8,18 are all lumped together..... you need to modify the exhaust in 18 so why not just allow the exhaust mods in ltd and let it fly and keep stock class what it is....

    #6 as long as the sensor is not connected to anything other than the gauge i dont see what the issue is in running it in any class. in the long run would it would increase reliability and lower costs and possibly prevent someone from blowing a motor.

    #7 i agree with.

    #10 you can buy it at a pump and its an unleaded fuel so i dont see why not. VP even sells E85 so i dont see what the issue is there

    #11 i agree with... give everyone a fighting chance

    #12. stupid... if you running at that level RWYB and hope its enough. at that point your turning open into limited. which will just open the door for cheating more than it already is

    #15 if its an OEM part why not...

    #16 all for it if its making the skis more reliable

    #17 redundant with 6&7

    #18 see above regarding 5,8,18

    #21 is good and would reduce everything by 1 class

    #22 agreed

    #23 bump it to two years unless petitioned and approved by competitiors in that class and IJSBA

    #24 agreed... get rid of the sandbaggers and give everyone else a chance

    #25 agreed if you are that level and have won that many times... move up
