When you're buying a used boat, understanding its past is one of the most important steps in the process. A clean history and well-documented service record can protect you from unexpected repairs and give you confidence that the boat has been cared for properly.
Use this guide to verify a boat’s background before you sign on the dotted line.

Ask the seller or dealership for any maintenance logs the owner kept. Good records usually include:
A well-maintained boat will generally have consistent records year after year. Missing history is not always a deal-breaker, but it should prompt a closer look at the mechanical inspection. A fifteen-year-old boat with seventy hours sounds great, but if it has never had preventative maintenance, that is a real concern.
Receipts tell the real story. Ask for documentation that shows:
If a dealership like Seattle Boat has performed the past maintenance, the records will usually be complete and easy to verify. You can also contact any shops listed on receipts to confirm the work and check for additional records in their files.
Even well-used boats can be great buys when their history is clear. It is important to ask directly about:
Repairs completed by a reputable service center are not necessarily negative. The key is knowing what was done and how the boat was cared for afterward. If a seller avoids these questions or gives vague or evasive answers, take note.
Where and how the boat was stored tells you a lot about its long-term health. Ask about:
Freshwater usage typically results in less corrosion over the years. Boats stored indoors or in dry stack usually experience less UV exposure and moisture, which helps preserve the upholstery, hull and mechanical systems.
If the boat is newer, parts of it may still be under warranty. Ask for:
Active warranties add value and peace of mind, especially on major components.
Engine hours do not tell the whole story. A well-maintained 600-hour boat can be a better purchase than a poorly maintained 150-hour boat. What matters is whether the hours, condition and maintenance records all make sense together.
If the engine was replaced or repowered, ask for:
Who you are buying from is almost as important as what you are buying.
Ask the seller:
Observe whether their answers are consistent with the records and condition of the boat. Be cautious of sellers who rush your decision, avoid inspections or decline to show the boat in person. If buying from a dealer, check reviews and ask about their inspection standards and service process. Dealerships are also more likely to provide on-water test drives that are also essential to verify performance, vibration, steering, noise levels and throttle response.
Once you have reviewed the documentation, bring in a certified marine technician for a pre-purchase inspection. This should include:
Physically inspect the flooring for soft spots, look for corrosion, check fluid colors and assess the general cleanliness of the engine compartment.
A professional inspection is the best protection against surprises after the sale.
Before you make a final decision, do a simple reality check:
A well-maintained boat will almost always offer better real-world reliability than one that simply looks good on the surface.
