  1. Shall IJSBA prohibit lithium ion batteries in Stock Class(es) unless OEM equipped?

Note: this item intends to restrict the provision for aftermarket batteries  (6.7.1 and 6.8.1) so that light weight lithium ion batteries are prohibited.  A “Yes” vote would specifically prohibit lithium ion batteries, however lightweight batteries that are not lithium ion types are not prohibited.  A “No” vote means no change to the Rule Book.

Answer: DID NOT PASS

  1. Shall IJSBA require Ski PWC in Open and GP Classes to be equipped with a boost pressure regulator?

Note: this item intends to prevent Ski PWC, which are equipped with a supercharger or turbocharger, from having unlimited boost pressure in Ski Open and Ski GP Classes. A “Yes” vote would mean that the same boost pressure regulator required for Ski Stock and Ski Limited classes would be required for Ski Open and Ski GP classes.  A “No” vote would mean no change in the Rule Book and boost pressure would remain unlimited.  Item 18 below sets the degree to which the boost would be limited.  Please choose one of the items in Item 18 even if you vote no for Item 17.

Result : DID NOT PASS

  1. If Item 17 is yes then shall that boost pressure regulator be set to release at:

a. 12 LBS PSI ?

Result (A. B. or C): “C,” HOWEVER NO EFFECT SINCE ITEM 17 DID NOT PASS

  1. Shall IJSBA change Rule 7.8.4.1 so that, in Limited Class(es), Ski type PWC shall have the required boost regulator release at 12 PSI?

Note:  IJSBA Rule 7.8.4.1  currently sets a scale of 10-14 PSI, and a default of 14 PSI, for the setting for the boost pressure regulator.  This items seeks to reduce the default to 12 PSI.  A “Yes” vote would change the default setting  from 14 PSI to 12 PSI.  A “No” vote means no change to the Rule Book.

Result: PASSED

  1. Shall IJSBA change Open Class(es) and GP Class(es), for Ski PWC, so that Open becomes normally aspirated and GP becomes the class that accommodates Ski PWC equipped with turbochargers and superchargers?

Note:  IJSBA Open Rules currently allow for Ski PWC to be equipped with superchargers and turbo chargers.  This item seeks to separate the two classes so that Open Class would no longer allow for superchargers or superchargers.  A “Yes” vote would remove any allowances for Superchargers and Turbochargers in Ski Open.  A “No” vote means no change to the Rule Book.

Result: DID NOT PASS

  1. Shall IJSBA create restrictor plate requirements for Runabout Class(es) to limit the top speed of Runabouts on closed course tracks?

Note:  IJSBA currently has no speed cap on any class.  This item seeks to create air flow limitations on Runabouts when competing in closed course events.  A “Yes” vote allows IJSBA to create a restrictor plate requirement to control top speeds in closed course.  A “No” vote mans no change to the Rule Book.

Result: DID NOT PASS

  1. Shall IJSBA change the maximum displacement in Runabout Rec Lites Class(es) to 1100cc with the following restrictions: 0-900cc for Runabouts Up to 450lbs and 1100cc for runabouts 720lbs and above?

Note: IJSBA currently has a maximum displacement in Runabout Rec Lites of 950cc.  This item seeks to allow additional displacement so long as there is additional weight to accompany the additional displacement.  A “Yes” vote would create two divisions of displacement: 1-900cc and 901-1100cc;  1-900cc Four Stroke Runbout must weigh 400 lbs minimum and 901cc and above four stroke runabouts must weigh a minimum of 720lbs.  A “No” vote means no change to the Rule Book and that the maximum displacement would remain at 950cc.

Result: PASSED

  1. Shall IJSBA modify Runabout Stock Class(es) to require the PWC to be entirely OEM under the seat?

Note: This item seeks to remove all allowances for Runabout Stock Class(es) other than those handling and cosmetic modifications that are outside of the hull (a.k.a. under the seat or under the hood).  A “Yes” vote modifies the Runabout Stock Class(es) to nearly OEM including repairs and replacement parts.  A “No” vote means not change to the Rule Book and leaves the Runabout Stock Classes as they exist now.  A “No” vote is not required to answer Item 23.  A “Yes” vote is not required to answer Item 24.

Result: DID NOT PASS

  1. If item 23 is No, are there other variations of allowances to remove?

Note: A variation of Item 23 would aftermarket removable flame arrestors and reprogramming of the OEM ECU but no other modifications to any items inside the hull (a.k.a. under the seat or under the hood).  A “Yes” vote here modifies Item 23, if passing in the majority but does not become active unless the majority votes “No” on item 23.  A “No” vote, here, leaves whatever is the result of item 23 in place.

TO AVOID CONFUSION:  IF YOU WANT RUNABOUT STOCK RULES TO REMAIN AS THEY ARE, VOTE NO ON ITEMS 23 and 24.  IF YOU WANT ALL OEM INSIDE THE HULL/ENGINE COMPARTMENT, VOTE “YES” ON ITEM 23 AND “NO” ON ITEM 24.  IF YOU WANT ALL OEM EXCEPT ECU REFLASH AND AIR FILTERS, VOTE “NO” ON ITEM 23 AND “YES” ON ITEM 24.

Result: PASSED

  1. If item 23is Yes, what is the implementation time for such a change?

Note: If there is any change in the allowances for the Runabout Stock Classes, should that change become effective:

a. 2015
b. 2016

Result: “B”

  1. Shall IJSBA modify Rule 8.2.2 to allow an additional two inches in widening of the Ski’s standing tray area for specific models with a narrow standing area?

Note: For simplicity purposes, this item applies only to Yamaha Superjets which currently cannot accommodate as wide of a tray as wide as other models under the current Open Class rules.  If this item passes, the language will be reduced to a mathematical formula as opposed to identifying the model by brand or name.  Further, if Item 7 passes, this item will become void as the tray width restriction will no longer be relevant.  A “Yes” vote means that Yamaha Superjets will be allowed an additional two inches of total width when widening the tray area than is currently allowed.  A “No” vote means that there will be no change to the Rule Book and the current width restrictions will apply.

Result: PASSED, HOWEVER, RENDERED INEFFECTIVE DUE TO THE PASSAGE OF ITEM 7

 

  1. Shall IJSBA modify Rule 6.4.5 to change “Additional cooling supply lines may be added to water inlet covers that are removable from the engine block.” To “ Water inlet covers that are removable from the engine block may be modified or aftermarket.”?

Result: PASSED

  1. Shall IJSBA increase Vintage Ski displacement to 800cc?

Note: In 2013, Rule Book voting reduced Vintage Ski displacement to 550cc for the 2014 season.  This item seeks to increase Vintage Ski displacement to 800cc.  A “Yes” vote allows Vintage Ski displacement up to 800cc.  A “No” vote retains 550cc maximum displacement for Vintage Ski.

Result: DID NOT PASS

  1. Shall IJSBA allow Ski Stock Class(es) to have the provisions of boring the steering nozzle and/or cross model updating/backdating steering nozzles from the same brand Ski?

Note:  IJSBA Rule 6.10.2 prohibits any boring or grinding on an OEM steering nozzle.  IJSBA Stock Class rules require updating/backdating of steering nozzles from the same model between different production years.  This item would allow both boring/grinding on OEM nozzles as well as updating/backdating of nozzles between models of the same brand.  A “Yes” vote means that boring and grinding of OEM nozzles would be allowed.  A “No” vote means no change to the Rule Book.

Result: DID NOT PASS

  1. Shall Veterans Runabout Class(es) switch from Limited Class Rules to Stock Class Rules for those Runabouts equipped with superchargers or turbochargers?

Note: IJSBA sets Veterans’ Runabout as a hybrid of Limited Class Rules for Runabouts equipped with a Supercharger or Turbocharger and Open Class Rules for normally aspirated PWC.  This item would require Runabouts equipped with a Supercharger or Turbocharger to adhere to Stock Class Rules in Veterans’ Runabout.  Further note that Items 23-25 impact the result of this item.  A “Yes” vote means that Veterans Runabout class PWC equipped with superchargers or turbochargers to adhere to Stock Class rules.  A “No” vote means that Veterans’ Runabout class PWC equipped with superchargers or turbochargers will continue to adhere to Limited Class Rules.

  1. Shall IJSBA modify the Runabout Normally Aspirated Class(es) so that Two Stroke powered PWC are scored separately from Four Stroke powered PWC?

Note:  IJSBA currently scores two stroke and four stroke platforms together in the Runabout Normally Aspirated Class(es).  This item would separate the scoring of Two and Four Stroke PWC in Runabout Normally Aspirated class(es).  A “Yes” vote would score Two and Four Stroke PWC separately in Runabout Normally Aspirated Class(es).  A “No” vote would continue Runabout Normally Aspirated classes as they are.

Result: DID NOT PASS

  1. Shall IJSBA modify Rules 6.6.3, 7.5.1, and 7.8.3.4 so that direction is given on how to manage any fuel return line changes?

Note:  This item seeks to add guidance to how fuel is to be returned to the fuel system if aftermarket fuel pumps and/or aftermarket fuel pressure regulators are installed.  A “Yes” vote means that there will be language instructing competitors on how to specifically return the fuel to the fuels system when an aftermarket fuel pump and/or and aftermarket fuel pressure regulator are installed.  A “No” vote means no change to the Rule Book.

Result: PASSED

  1. Shall IJSBA add language to Rule 12.4.2 to specify penalties for missing a log jump and any exceptions to those penalties?
