Pre-Purchase Boat Inspections: Uncover Hidden Issues Before You Buy

Know the Boat Before You Sign

Buying a boat is a significant investment, and a used boat can hide costly engine and system problems that fresh wax, clean cushions and a short run around the harbor will not reveal. Our boat pre-purchase inspections give boat buyers a detailed written assessment of the engines and systems before the money changes hands, so you can negotiate confidently, ask the seller to address problems, or walk away.

Many buyers search for marine surveying or a pre-purchase survey when they need this kind of check, so it is worth being clear about what we provide. This is a pre-purchase boat inspection carried out by our marine mechanics, the same team that repairs engines and onboard systems; we are not marine surveyors. A lender or insurer may require a survey by an accredited marine surveyor, and we recommend one in any case: our inspection is not a substitute for that survey.

What a Boat Pre Purchase Inspection Covers

Every boat is different, so we agree the scope with you in advance. The inspection typically covers the critical mechanical and electrical components, plus a visual check of the hull and deck. Think of it as a condition check from people who fix boats for a living.

Hull and deck

We look over the hull and deck for visible cracks, soft spots underfoot, blisters, impact damage and signs of earlier repairs, and check the transom, deck hardware and fittings. Judging the structure (moisture readings, sounding for delamination) is a marine surveyor's job, so we recommend a survey by an accredited marine surveyor as well. The bottom, running gear and underwater fittings can only be seen properly when the boat is hauled out, which the buyer usually arranges with the seller.

Engines and drive systems

We check the engines, outdrives or shafts and propellers for leaks, corrosion, signs of overheating and wear, and compare the hours with the maintenance history. Where the seller allows, we run the engines and watch how they start, idle and warm up. Compression testing or oil sampling can be discussed when the engines are a major part of the price.

Onboard systems and safety

We look at the fuel system, batteries, wiring and charging, bilge pumps, through-hulls and seacocks, steering and controls, cooling and exhaust, and the condition of the safety equipment on board. If the seller permits a sea trial, we observe how the boat and its engines behave under way.

How a Marine Pre Purchase Inspection Works

Before the visit

Arrange access to the boat with the seller or broker, gather any service records the seller can provide, and tell us which parts of the boat matter most to you as the buyer.

On the boat

Our technicians look over the hull and deck and work through the engines and systems within the agreed scope, and record what they find.

Your report

You receive a written report on what we inspected, and we explain which findings affect safety and which are routine maintenance, so you have a clearer view of the boat's condition before you commit.

Frequently asked questions about boat inspection

Is a pre purchase boat inspection the same as a formal marine survey?

No. It is a hands-on inspection by marine mechanics, not a survey. A lender or insurer may require a survey by an accredited marine surveyor, and we recommend one; confirm exactly what they require before booking.

Does the boat need to come out of the water?

Much of the inspection can be done at the dock. To see the bottom, running gear and underwater fittings, a haul-out is needed, which the buyer usually arranges with the seller and the boatyard.

What if the inspection finds problems?

That is exactly what the inspection is for. You can use the findings to negotiate, ask the seller to repair specific items before the sale, or decide the boat is not right for you. If you go ahead with the purchase, we can also help plan the repairs.
