Michigan boat registration is handled by the Department of Natural Resources, not your local Secretary of State office
Boat registration in Michigan works differently from car registration. The Michigan Department of Natural Resources (DNR) issues boat registrations, and you explore through them rather than through your county clerk or Secretary of State. The registration is valid for three years and covers any motorized vessel, sailboat over 20 feet, or personal watercraft you operate on Michigan waters.
You can register your boat online through the DNR website, by mail, or in person at a DNR office. The process takes about two weeks by mail and is faster online. You will need proof of ownership (a bill of sale, title, or manufacturer's certificate), proof of Michigan residency, and the hull identification number (HIN) from your boat.
Key Takeaways
- Michigan boat registration is issued by the Department of Natural Resources and lasts three years, not one year like vehicle registration.
- You need a bill of sale, proof of residency, and your boat's hull identification number before you can register.
- Online registration through the DNR website is the fastest method and takes a few business days.
- Registration covers motorized boats, sailboats over 20 feet, and personal watercraft; non-motorized boats under 20 feet do not require registration.
What boats require registration in Michigan
Not every boat needs to be registered. Michigan requires registration for any vessel with a motor, regardless of size. This includes outboard motors, inboard motors, jet drives, and electric motors. Sailboats must be registered only if they are 20 feet or longer. Non-motorized boats—canoes, rowboats, kayaks, and sailboats under 20 feet—do not need registration.
If you own a personal watercraft (jet ski, Sea-Doo, or similar), it must be registered. The same three-year registration period applies. If your boat is registered in another state and you bring it to Michigan, you have 60 days to register it in Michigan if you become a resident or keep it in Michigan waters for more than that period.
Documents you need to register your boat
Gather these documents before you start the registration process. You will need proof of ownership: a bill of sale, a manufacturer's certificate of origin, a previous registration from another state, or a title if your boat is titled in Michigan. You also need proof of Michigan residency—a driver's license, utility bill, lease, or mortgage statement with your current address.
Find your boat's hull identification number (HIN), which is usually on a metal plate on the transom (back) of the boat or on the starboard (right) side near the water line. Write down the exact number; the DNR will verify it matches your boat. If your boat does not have a visible HIN, contact the DNR before registering—some older boats may need an inspection.
How to register online through the DNR
The fastest route is the Michigan DNR's online registration system. Go to the DNR website and select "Boat Registration" under the Licensing section. You will create an account, enter your personal information, and upload images or scans of your proof of ownership and proof of residency. The system will ask for your boat's HIN, length, type (motorized, sailboat, personal watercraft), and motor details if applicable.
Review all information before submitting. The DNR will send you a confirmation email within one business day. Your registration certificate and decals will arrive by mail within two weeks. You must display the registration decal on both sides of your boat's bow (front). Do not operate the boat until the decals arrive and are in place.
Registering by mail or in person
If you prefer not to register online, read the boat registration form from the DNR website (Form 2915) and mail it with copies of your proof of ownership and proof of residency to the address listed on the form. Include a check or money order for the registration fee. Processing takes two to three weeks from the date the DNR receives your packet.
You can also register in person at any DNR office during business hours. Bring the original documents (not copies) and payment. The staff will verify your information on the spot and issue you a temporary registration receipt. Your permanent registration certificate and decals will still arrive by mail within two weeks. DNR office locations and hours are listed on their website.
Registration fees and renewal
The registration fee depends on your boat's length and type. Motorized boats are charged by length in five-foot increments; a boat under 20 feet costs less than one 20 to 26 feet. Personal watercraft have a flat fee. Sailboats 20 feet and over are charged by length. The DNR website lists the current fee schedule, which changes yearly. You can also call the DNR licensing office to ask for the exact fee before you register.
Your registration is valid for three years from the date of issue. The DNR will send you a renewal notice by mail about 30 days before expiration. You can renew online, by mail, or in person using the same process as initial registration. If you do not renew before the expiration date, you cannot legally operate the boat on Michigan waters until you do.
What to do if your boat is titled in Michigan
Some boats are titled through the Michigan Secretary of State, similar to vehicles. If your boat has a Michigan title, you still register it through the DNR—the title and registration are separate documents. The title proves ownership; the registration allows you to operate it. When you register a titled boat, provide the title as your proof of ownership instead of a bill of sale.
If you buy a used boat with a Michigan title, the seller must sign the back of the title and give it to you. Take the signed title to the Secretary of State to transfer ownership into your name before registering with the DNR. This step is required even though the DNR handles registration. The Secretary of State charges a transfer fee, which varies.
Frequently Asked Questions
Can I register a boat I just bought without a bill of sale?
The DNR accepts a manufacturer's certificate of origin, a previous registration from another state, or a title as proof of ownership. If you have none of these, ask the seller for a bill of sale. If the boat is very old and no documents exist, contact the DNR to ask about an inspection or affidavit process.
What happens if I operate a boat without registration?
Operating an unregistered boat on Michigan waters is a violation. You can be cited and fined. The fine amount varies but can be substantial. If you are stopped by a conservation officer, you must show your registration certificate or decals.
Do I need to register a boat I only use on private property?
If the boat never enters public waters, registration is not required. However, if you ever launch it on a lake, river, or public waterway in Michigan, it must be registered before you do so.
How long does online registration take?
You receive a confirmation email within one business day of submitting online. Your physical registration certificate and decals arrive by mail within two weeks. You cannot legally operate the boat until the decals are displayed on the bow.
Can I register a boat with an out-of-state address?
No. You must be a Michigan resident to register a boat in Michigan. Proof of residency is required. If you move to Michigan, you have 60 days to register any boat you own before it becomes mandatory.
