Before you drive anywhere, ask whose name is on the title and whether the trailer has its own, ask for a photo of the hull number on the transom, ask when the engine last ran and who last serviced it, and ask how they want to be paid and where the boat is kept. Put them in writing, and a listing with a problem has to dodge one of them before you spend the drive.
The inspection guide covers what to check once you are standing next to the boat. This page is the message you send before that, while the listing is fresh and the trip is still free to cancel. Each question below links to the guide that explains why it is worth asking.
Whose name is on the title, and is there one for the trailer?
"No title" covers three different situations: a boat your state never titled, a title the owner lost, and a boat that is not the seller's to sell. Only the seller can tell you which one you are dealing with, and the third is usually described in the friendliest language. What "no title" actually means takes each one apart, and the state-by-state title guide tells you whether your state titles this boat at all.
Ask about the trailer in the same message. It normally carries its own title and its own VIN, and some states title the outboard separately as well, so a seller who says "I have the title" may be talking about one object out of two or three.
- Ask: Is the title in your name, and will that person be there on the day? Is there a separate title for the trailer? Is there a lien on it, and if there was, do you have the release?
- Red flag: the title is in a relative's or an ex-partner's name and that person cannot be reached, or the story about who they are changes between messages.
Can you send a photo of the HIN on the transom?
The twelve-character hull identification number sits on the starboard side of the transom, near the top, and it is the number the title records for the hull. A clear photo lets you run it through the HIN decoder and compare its model year with the year in the advert, and set it against a photo of the title, character by character, before you leave the house.
- Ask: Could you send a photo of the hull number on the back of the boat, and one of the title?
- Red flag: a refusal, or a photo that is cropped, blurred or taken from an angle that does not match the boat in the listing. How to check if a used boat is stolen covers what a tampered number looks like once you are there.
When did the engine last run, and who last serviced it?
"Ran when parked" means the engine ran at some point in the past and the seller is not claiming it runs now. Assume it does not, and price it that way: what "ran when parked" costs lists what the usual phrases tend to mean in repairs. "Low hours" means nothing without a number, and very low hours on an old engine is a question rather than a selling point.
Ask when the lower unit oil was last changed and whether it came out milky. It is the cheapest question in the whole conversation, and the answer can be one of the most expensive. Ask the seller not to start the engine before you arrive, too, since a cold start is one of the things you will want to see.
- Ask: When did it last run, and how many hours are on it? Do you have service records? When was the gear lube last changed?
- Good sign: service records, a compression test, or a dated receipt. Someone has done the work and can show it.
Is the trailer included, and will it get the boat home?
Nobody buys a boat for the trailer, which is why it gets ignored. It has often sat outside for years, it is the part the seller never maintained, and it is the part that can fail on the highway with your new boat on top. A listing that says "no trailer" means you still need one, and a way to get the boat home on the day.
- Ask: Is the trailer included and titled or registered in your name? When were the bearings last done? How old are the tires? Do the lights work?
- Then check: the trailer checks cover bearings, tire date codes, lights and welds for when you get there.
How do you want to be paid, and can I see it where it's kept?
There is no honest version of a private boat sale where you cannot go and look at the boat. A sympathetic reason you can't visit (a transfer, a deployment, an estate), followed by an offer to ship it through an agent or escrow the seller picked, is a known scam pattern. So is a request for a deposit to hold a boat you have not seen.
Payment answers sort listings quickly. Gift cards are always a scam. A wire transfer is effectively cash and is usually gone for good. How Marketplace boat scams work walks through each one. And a seller who wants to meet in a parking lot or at a ramp rather than where the boat lives, with no clear reason, is worth a second look at the paperwork.
- Ask: Can I see it where it's kept? How would you like to be paid once I've seen it?
- Red flag: shipping only, a deposit before viewing, gift cards, a wire, or an escrow service the seller chose.
A first message you can copy
Send it as one message, so the seller answers everything at once and you can compare the replies side by side if you are messaging about more than one boat.
Hi, is the boat still available? A few questions before I drive out:
- Is the title in your name? Is there a separate title or registration for the trailer?
- Could you send a photo of the hull number on the back of the boat?
- When did the engine last run, how many hours are on it, and do you have service records?
- Is the trailer included, and when were the bearings last done?
- Can I see it where it's kept? Please don't start the engine before I get there.
Thanks.
The questions in one table
| Ask | A good answer | A red-flag answer | Guide |
|---|---|---|---|
| Is the title in your name? | Yes, and here is a photo, or your state does not title this boat | Someone else's name, and they can't be reached | No title |
| Can you send the HIN? | A clear photo that decodes to the advertised year | No photo, or a cropped one | HIN decoder |
| When did it last run? | A date, hours and service records | "Ran when parked" | Ran when parked |
| Is the trailer included and titled? | Yes, with its own paperwork | No paperwork for it, or no trailer at all | Trailer checks |
| Can I see it where it's kept? | An address and a time | Shipping only, or a parking lot for no clear reason | Scams |
| How do you want to be paid? | Once you've seen it | A deposit to hold it, gift cards or a wire | Scams |
Questions buyers ask
Should I ask for the HIN before I see the boat?
Yes. It costs an honest seller one photo, and it lets you decode the number and set it against the title before you spend the drive. A seller who will not send it has answered a different question.
What if the seller wants to move to text or WhatsApp?
Plenty of people dislike Messenger, so it is not proof of anything. Keep the deal itself agreed on Marketplace, where the seller can be reported, and stop if the reason for moving is vague. The Marketplace scams guide explains why that move comes first in nearly every scam.
Is "ran when parked" a reason to skip the boat?
Not on its own. It means the engine ran at some point and the seller is not saying it runs now, so price the boat as if it does not. What "ran when parked" costs puts the repair on the other side of that sum.
Does the trailer need its own paperwork?
Usually. The trailer has its own VIN stamped on the frame and often its own title, though some states do not title trailers under a set weight. So "I have the title" can cover the boat and not the trailer. Ask which one they mean.
