Class Assignments and Inspection Procedures:

  • All equipment to be raced must be pre-season inspected and receive class assignment. It is the Racers responsibility to contact the NIDBA and make arrangements to have this process completed two weeks prior to the first race of the year. An NIDBA Official will be available any time prior to that. The NIDBA will create an “Inspection Day” if enough Racers feel they can all get themselves together on a given date.
  • During Pre-season inspection, your equipment will be thoroughly safety inspected and the motor thoroughly inspected. Internal engine inspection may be performed if the NIDBA Official deems it necessary. Your equipment at that time will be given a Class assignment by the Outboard Race Committee (ORC). The ORC may require the owner to make arrangements for the equipment to be weighed if deemed necessary for proper class assignment.
  • No Local Racers will be allowed to participate without Pre-season inspection.
  • Out of town Racers or, competitors coming in from out of town for a special event are required to contact the NIDBA to make special arrangements. There will be no pre race inspections at the race site.
  • Considerations for someone who purchases new equipment after the first race of the year may be made. It is the racers responsibility to make sure this process is completed promptly. Any equipment receiving a re-rig, re-power, or has changed hands must be re-inspected.
    Requirements to “make” a class
  • Each Outboard class will require a minimum of at least 1 legal boat and 1 approved step-up for a given class to constitute a class.
  • If a given class has no legal entries, boats from the next lower class may be approved to step up. Racers will be awarded normal points and prize money. The ORC may limit the number of entries if any depending on daylight.


    • Racers will accumulate the following points:
        100pts. for show up
        50 pts. for each completed pass, including a bye run
      50 pts. for winning the final
  • To be eligible for show up points your equipment must be able to leave the pit area and cross the starting line under its own power.
  • No show up points will be given to a racer who shows up without a legal boat for that class.
  • If a Racer is in contention for high points for the year, and has failed equipment, he may show up and make at least one pass with a legal NIDBA boat from a lesser class to obtain points.
  • If the weather goes away after registration and the NIDBA closes the course for the day, registered boats will receive equal, or show up points. Racers that do not make it to the race site and have verified to have made a valid attempt to race will also receive show up points if a race is called after the racers have been notified the race was on for the day.


  • For classes Lake Racer and above, pairings will be made by a random drawing at registration. For Pro Sport boats pairings may be made by an NIDBA Official or a drawing.


  • Life jackets in all classes Lake racer and above will be NIDBA approved and in certification, All Competitors in Lake Racer and above with short jacket are required to have ballistic pants or similar.
  • Life jackets in Pro sport must be a minimum of a 100mph Ski Vest with leg straps.

Boat Safety Equipment:

  • All boats are required to have a tether assembly it is required to disable the ignition, and the electric fuel pump if external.
  • During your Pre Season inspection we will be checking for proper mounting of batteries, fuel tanks, steering, wiring, motor mounting, added weight and many other items, the NIDBA Official will cover these details with you at inspection because different equipment may have unique requirements.
  • Any loose gear that does not affect your class assignment must be removed while racing.
  • Throttle return springs are required at the foot throttle, throttle linkage, and the butterfly.
  • Capsule Outboard Drag boats will comply to the safety rules outlined by the sanction they commonly race in (ODBA/DSRA). They will have roll over kill systems as well as external battery and ignition shut offs. OPC Capsule boats used for drag racing will comply to all APBA OPC safety rules. Air systems are recommended for capsule style outboard drag boats, air systems will be mandatory for OPC style capsule boats.

Technical Inspection:

  • A Technical Inspection(TI) may be called at any time. There will no longer be any inspections at the venue, as well, there will be unannounced inspections at the ramp, pre or post race. If the Inspector asks you to tech and you don’t launch your boat at the ramp it’s the owners responsibility to get the boat into a position that the tech inspectors can do their job.
  • If you are ordered to have a TI by the referee, the procedure is as follows. Your boat will remain secured to the slip until the referee releases you. At that point in time an NIDBA Official may escort you to your trailer if the referee deems it necessary. The referee will notify you of that before you are released. If you leave before the Referee releases you, you will lose a All points for the day, and the next race you enter.
  • During any Inspection the only people allowed to participate are the Inspector, the boat Owner/Driver, and one Crew member.
  • Anyone who refuses Pre race inspection loses the right to race that day. Anyone who refuses inspection post race loses ALL points for the day, and the previous day. If it is the first night of racing you will give up the points from the next day you race. Anyone who refuses any type of inspection or has failed inspection will be required to be inspected prior to any further racing.
  • The Inspector reports his findings to the Referee, the ERC will review the situation and report back to the boat Owner/Driver.
  • After any inspection it is the Owners/Drivers responsibility to verify his equipment is reassembled correctly and in running order.


  • After competition drivers retain the right to protest a possible violation of the rules affecting ONLY their class of registration. If the protest concerns a disqualification, eligibility or legality of an entry, the protest must be filed with the Referee in writing. The protest must be received by the Referee no more than one hour after the finish of the last heat in the class that the infraction occurred. Or, less than one half hour after the last heat of the day’s racing, whichever comes last. A protest carries a $50 filing fee. Protests should be specific, factual, rule based, and as complete as possible.
  • At this point the Referee will make the determination of what action will follow. The protested equipment will remain at the slip until the Referee has decided what actions need to be taken.
  • If the protest is determined to be correct , the person who filed is reimbursed his fee. If the protest is found to be incorrect, the fee is retained by the NIDBA.
  • Starting violations cannot be protested.
  • Any Racer who has been caught with an infraction, been protested against, or handed down a penalty may appeal that decision.
  • The appeal must be filed in writing within 24hrs. of being notified you have been penalized. There will be a $50 filing fee. If your appeal overturns a decision against you, the fee is returned to you. If the appealed decision stands, the NIDBA retains the fee.
  • There will be no “re-inspection” for the appeal process. Only information gained during the original inspection will be considered.

As always, if there are any confusion or questions, please contact any of the ORC members for clarification. The NIDBA and the ORC govern these rules and procedures and retain the right to the final decision.
