Questions to Ask When Buying a Boat
Questions to ask a seller or dealer before buying a boat, covering engine hours and service history, storage and salt exposure, hull and deck condition, the trailer, sea trials and surveys, running costs, and the title.
The questions
Open any question for the note
How long have you owned it, and how many hours are on the engine?
Why ask it
Hours tell you more than model year, and a low-hour engine that sat unused is often in worse shape than a well-used one. Read the hour meter yourself rather than accepting the figure in the listing.
Where has it been kept: on a trailer, in dry storage, or in the water?
Why ask it
A boat that lives in the water carries bottom growth, blister, and corrosion risk that a trailered boat does not. Ask when the bottom was last painted and when it was last hauled and inspected.
Has it run in salt water, and what was the flushing routine?
Why ask it
Salt without disciplined flushing shortens the life of cooling passages and every metal fitting on the boat. An owner who describes their routine in detail usually has other habits to match.
Can I see the service records, and who did the work?
Why ask it
Look for continuity: oil and gear lube intervals, impeller changes, and a named shop. A folder that stops three years before the sale usually marks the point the owner lost interest.
When were the impeller, belts, and fuel filters last changed?
Why ask it
These are cheap scheduled items whose neglect leaves you drifting. An owner who cannot date them is telling you the rest of the maintenance schedule is guesswork too.
Has it ever taken on water, been submerged, or been through a salvage claim?
Why ask it
Ask directly, then check the title for a salvage brand. Rainwater in the bilge is routine; water over the engine or up the wiring is a different boat entirely.
Are there soft spots in the deck, stringers, or transom?
Why ask it
Wet core is the boat equivalent of frame rot and the repair is measured in weeks of labor. Walk the deck and press the transom yourself, and watch how the seller reacts to the question.
How old is the fuel tank, and how old is the fuel in it?
Why ask it
Ethanol-blended fuel degrades over a season and aluminum tanks corrode from the outside where they sit against foam. Ask when it was last filled and whether it has been treated.
What condition is the trailer in: bearings, brakes, tires, lights?
Why ask it
Trailer tires age out long before the tread wears down, and a bearing failure on the drive home is the classic first-day expense. Check the trailer title and its load rating against the boat's weight.
What electronics, canvas, and upholstery are included, and how old are they?
Why ask it
Covers, seats, and a chartplotter each cost real money to replace and all have shorter lives than the hull. Ask which of them are original and which have been redone.
What safety equipment comes with it, and is it current?
Why ask it
Flares expire, extinguishers lose charge, and life jackets have to fit the people who will actually wear them. Whatever is missing becomes your expense before the first outing.
Can we take it out on the water, and will you come along?
Why ask it
A trial run to full throttle shows whether it reaches rated RPM, tracks straight, and shifts cleanly hot. A seller who offers only an idle around the marina is protecting something.
Will you allow a marine survey and an oil or compression test?
Why ask it
A survey is what your insurer and lender will want anyway, and oil analysis finds internal wear no test run reveals. Refusal is the clearest signal you will get in the whole process.
What does it cost you a year to keep, all in?
Why ask it
Slip or storage, insurance, winterizing, bottom paint, and registration usually dwarf fuel. Ask for last year's actual figures rather than an estimate, and ask which of them got skipped.
What is slip or storage availability like around here?
Why ask it
In many areas the waitlist for a slip is the binding constraint rather than the boat itself. Confirm you have somewhere to keep it before you own it.
What will insurance require, and can I get a quote before closing?
Why ask it
Insurers may want a recent survey, specific equipment, or a boating course, and older hulls can be hard to place at all. Get the quote while walking away is still an option.
Where is the title, and are there liens on the boat, engine, or trailer?
Why ask it
Engines and trailers are titled separately in many states, and a lien on any of the three can block your registration. Get the hull identification number and check it before money moves.
What does this boat not do well?
Why ask it
Every hull has conditions it hates. An owner who names them is giving you calibrated information rather than a pitch: a wet ride in chop, poor handling at low speed, a draft that limits where you can go.
What have you replaced, and what were you planning to do next?
Why ask it
The list of what comes next is the honest defect list, phrased in a way the seller is comfortable saying out loud. It usually predicts what the survey will find.
What are you asking, what is included, and how do we handle the paperwork?
Why ask it
Get the inclusion list in writing, since electronics, covers, and spare props go missing between the showing and the handover. Agree who files the title transfer and when payment changes hands.
Inspecting and buying a boat
Practical guidance for the conversation itself
What to check before a survey
- Look at the bilge with a flashlight for oil sheen, rust streaks, and water that should not be there
- Press the transom and walk the deck barefoot listening for flex or a dull sound
- Check the outdrive or lower unit for gear oil weeping and for a chewed prop
- Look at the wiring for household-grade connectors, electrical tape, and corroded terminals
- Open every locker and hatch, since sellers stage the visible areas and forget the rest
- Check the engine oil for a milky look, which points at water intrusion
- Sight down the hull sides in raking light for repaired damage and mismatched gel coat
- Cycle the bilge pump, blower, horn, and navigation lights while you are aboard
The cost of ownership, honestly
- Slip fees or dry storage, which in many areas exceed the loan payment on an older boat
- Insurance, which may require a survey for an older hull before it can be written at all
- Winterizing and shrink wrap, or year-round bottom paint and haul-outs in warm climates
- Annual service: oil, gear lube, impeller, plugs, filters, and anodes
- Registration, and in some states a personal property tax
- The fund for the one big item, since an engine, an outdrive, or a canvas replacement arrives eventually
Where boat buyers lose money
Skipping the survey on a private sale
A survey costs a small fraction of a repower and is the only independent read you will get. It is also the document your insurer and lender are likely to require anyway.
Buying in winter without a water test
Off-season deals are real, but a boat that cannot be run cannot be assessed. If you buy without a trial, make the price reflect that risk or make the sale conditional on a spring test.
Forgetting the tow vehicle
Boat, trailer, fuel, and gear together can exceed what your vehicle is rated to pull and stop. Check the loaded weight against your tow and payload ratings rather than the dry hull weight.
Ignoring the trailer
People inspect the boat carefully and take the trailer on faith. Bearings, brakes, tires, and a rusted frame are the most likely thing to strand you on day one.
