Oklahoma Boat Equipment Requirements

  1. All boats must be titled and registered through the Oklahoma Tax Commission within 30 days of purchase. Outboard motors over 10 horsepower must also be titled and registered within 30 days of purchase. You may operate your boat within the first 30 days of ownership, prior to applying for your title and registration, if you carry on board the original bill of sale. Once the boat has been titled and registered, a copy of the current vessel registration (and outboard motor registration if applicable) must be available for inspection at all times.

    Boats currently registered in another state may use Oklahoma waters, so long as they do not exceed 60 calendar days. Boats remaining in Oklahoma for more than 60 days must be titled and registered in Oklahoma.

    All boats must properly display the registration numbers and a current registration decal.

    Registration numbers shall be displayed as follows:
    1. Must be painted, applied as a decal, or otherwise affixed to both sides of the bow as high above the water line as possible.
    2. Must read from left to right on both sides of the bow.
    3. Must be in bold BLOCK characters that are at least three inches in height and one-half inch in stroke width.
    4. Characters must be in a color that contrasts sharply with the background color of the hull.
    5. Letters must be separated from the numbers by a space or hyphen.
      Example: OK 3456 AB or OK-3456-AB
    6. No other numbers may be displayed on either side of the bow.
    7. Regsitration decals must be affixed on both sides of the bow, behind (towards the stern) and in line with and within six inches of the registration number.


  2. All boats must carry one wearable United States Coast Guard-approved personal flotation device (life jacket) for each person on board. In addition to wearable life jackets, boats 16 feet or greater in length must also carry a USCG approved Type IV Throwable device.

  3. All PFDs must bear a USCG-approved label, must be in good and serviceable condition, must be of suitable size for the intended person, and approved for the activity.

  4. All boats using flammable liquid as fuel are required to have the proper type, size and number of fire extinguishers on board.

  5. All boats are required to carry on board a whistle or horn or other legal mechanical sound producing device.

  6. All powerboats (except outboards) must be equipped with a USCG approved backfire flame arrestor on each carburetor.

  7. All gasoline powered boats, constructed in a way that would entrap fumes must be equipped with a proper and efficient ventilation system in order to remove flamable gases and reduce the chance of an explosion. Power ventilation systems should be turned on for at least four minutes both after feuling and before starting your engine.

  8. All powerboats must have a factory-installed muffler or exhaust water manifold for noise reduction or another effective muffling system. Mufflers may not be altered or modified in a way that increases noise. Use of cutouts, removing or altering baffles or cutting or punching holes in mufflers is prohibited.

  9. Every boat must display lights between the hours of sunset and sunrise, and must display required lights during times of restricted visibility (fog, heavy rain, mist, etc.).
