Buying a Boat from a Private Seller in Arizona: What to Check
Private party boat sales make up about 60% of used boat transactions in Arizona. You can often get a better deal than buying from a dealer, but you're also taking on more risk. The seller isn't required to offer any warranty, and you're responsible for verifying everything about the boat's condition and history.
This guide walks through the specific things you need to check when buying from a private seller in Arizona, including some issues that are unique to our desert climate.
Start with the title and registration
Before you even look at the boat, ask the seller to send a photo of the title. You're checking three things:
- The name on the title matches the seller's ID
- There are no liens listed
- The hull identification number (HIN) on the title matches the boat
If the seller says they lost the title, walk away. Arizona requires a title for all boats, and getting a duplicate takes about two weeks. A seller who doesn't have the title in hand is either disorganized or hiding something. Either way, it's not your problem to fix.
Some sellers will say the bank has the title because they're still paying off the loan. That's fine, but you'll need to coordinate payoff with the lender directly. Get the loan account number and lender contact info, then call to verify the payoff amount before you agree on a price.
Check the hull identification number in person
The HIN is stamped on the transom (back right corner of the boat, top of the hull). Bring the title with you and verify the numbers match exactly. If they don't match, stop the inspection. The boat could be stolen, or the title could be from a different boat.
Also check that the HIN plate hasn't been tampered with. It should be riveted or permanently attached. If it looks like someone removed and reattached it, that's a red flag.
Inspect for Arizona sun and heat damage
Arizona sun destroys gel coat, vinyl, and rubber faster than almost anywhere else. Most boats stored outdoors here will show some level of sun damage after three to five years. That's normal. What you're looking for is damage that affects function or safety, not just cosmetics.
Gel coat: Check the hull and deck for chalky, faded, or cracked gel coat. Light fading is cosmetic. Deep cracks that you can catch your fingernail in may indicate the fiberglass underneath is compromised. Pay special attention to the area around the transom and any through-hull fittings.
Vinyl and upholstery: Sit on every seat. Press down hard. Vinyl that's been sun-damaged will crack or tear easily. Check under the cushions for mold or water staining, which indicates the foam absorbed water and never dried out.
Rubber and hoses: Squeeze every hose you can reach in the engine compartment. They should feel firm and flexible. If they're hard, brittle, or cracked, budget for replacement. Also check the impeller (if you can access it). A heat-damaged impeller will have missing or cracked vanes.
Run the engine, on the water if possible
A lot of private sellers will run the engine on a hose in the driveway and call that a test. That tells you the engine starts, but not much else. You need to see the boat under load, on the water, to know if it actually runs correctly.
If the seller refuses a water test, that's a bad sign. Either the boat has a problem they know about, or the registration is expired and they don't want to launch it. Either way, you should not buy a boat you haven't seen run on the water.
During the water test, check:
- Engine starts easily (should start within three seconds of cranking)
- No unusual smoke or smells
- Smooth idle with no misfiring or surging
- Good acceleration with no hesitation
- Engine reaches normal operating temperature (check the gauge)
- Steering feels tight with no play or grinding
- Trim tabs or trim system works smoothly
- Bilge is dry after running (a little water is fine, a lot is not)
Take the boat up to cruising speed and hold it there for at least five minutes. Some problems only show up after the engine is fully warmed up.
Check the trailer carefully
The trailer is part of the purchase, and it can be expensive to replace. Arizona's dry climate is actually easier on trailers than humid areas, but you still need to check:
- Tire tread depth and age (look for the DOT date code on the sidewall; replace tires older than six years)
- Wheel bearings (jack up the trailer and spin each wheel; it should spin freely with no grinding or play)
- Frame for cracks or rust (especially near the tongue and axle mounts)
- Lights all work
- Coupler latches securely and safety chains are present
If the trailer needs work, factor that into your offer. A full set of trailer tires costs $400 to $600. Wheel bearings are another $200 to $300 if you pay a shop to repack them.
Get a bill of sale with specific language
Arizona doesn't provide an official bill of sale form for boats, so you and the seller need to write one. It should include:
- Buyer and seller names and addresses
- Date of sale
- Hull identification number
- Year, make, and model
- Sale price
- Statement that the boat is sold "as-is" with no warranty (unless you negotiate otherwise)
- Statement that the seller has clear title with no liens
- Both signatures
Both you and the seller should keep a copy. You'll need it when you register the boat with the Arizona Game and Fish Department.
Payment and common scams
Never wire money or send a deposit before you've seen the boat in person. If the seller asks for payment through Venmo, Zelle, or cash app before you take possession, walk away. Those payment methods have no buyer protection.
The safest way to pay is to meet at the seller's bank. You bring a cashier's check or cash, the seller signs over the title, you hand over payment, and the transaction is done. Some banks will notarize the bill of sale for free if you're a customer.
If the seller still owes money on the boat, meet at their lender's branch. You pay the lender directly for the loan payoff, and if there's money left over, you give that to the seller. The lender releases the title to you once the loan is paid.
After the sale: registration and insurance
You have 15 days to register the boat with Arizona Game and Fish. You'll need the signed title, bill of sale, and payment for registration fees (usually $40 to $60 depending on the boat's length). You can register in person at any Game and Fish office or by mail.
Get insurance before you tow the boat home. Most auto insurance policies do not cover boat trailers or the boat itself. A basic liability policy for a small boat costs about $200 to $300 per year. If you're financing the boat, the lender will require full coverage, which typically runs $400 to $800 per year depending on the boat's value.
Red flags that should end the inspection
Some issues are negotiable. Some are deal-breakers. Walk away if you see:
- Title doesn't match the seller's ID
- HIN doesn't match the title
- Seller refuses a water test
- Significant hull damage or soft spots in the deck
- Engine smokes heavily or won't reach operating temperature
- Seller pressures you to decide immediately or won't let you bring a mechanic
- Price is far below market value with no clear reason why
Buying a boat from a private seller takes more work than buying from a dealer, but it's often worth it. You can save 15% to 25% compared to dealer prices, and many private sellers are motivated to sell quickly. Just make sure you verify everything before money changes hands.
