Boat repair: what to know

What the job involves, what changes the price, and what to ask a pro.

What boat repair is

A technician repairs boat engines, electrical systems, steering, hull damage and fittings, working at a marina, boatyard or your dock. You need it when the engine will not run, the boat takes on water, the steering stiffens, or the electrical system fails.

Signs you need it

  • The engine is hard to start, runs rough or overheats
  • The boat takes on water or the bilge pump runs often
  • The steering is stiff, loose or makes noise
  • Electrical systems like lights, the battery or the instruments fail
  • The hull has cracks, soft spots or damage from a collision or grounding

What the pro does

  • Inspects the engine, electrical system or hull and records the findings
  • Tests the systems with the right tools, including compression and electrical readings
  • Explains the fault and gives a written estimate with parts and labor
  • Repairs or replaces the failed parts, such as a pump, hose, wiring run, cooling part or steering component, within the work the technician is trained to do
  • Tests the boat after the repair in the water or at the dock where it is safe

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • The engine type and how hard it is to reach the failing part
  • Whether the work is at a marina, boatyard or your dock
  • Whether the hull needs structural repair or only cosmetic work
  • Whether the electrical system needs new wiring or only a fix
  • The size of the boat and how much of it must be lifted or hauled out
  • Whether the parts must be ordered from a supplier or are in stock

What a written quote should spell out

  • The system repaired and the test used to confirm the fault
  • Each part, its brand and whether it is new or used
  • Labor for each repair step and any haul out or launch
  • Any sealants, resin or consumables used
  • Warranty for the parts and labor

Questions to ask before you hire

  • Can you show me the fault or the damage during the visit?
  • Do you check for hidden water damage in the hull or the bilge?
  • Will the boat be tested in the water before I pick it up?
  • Do you have experience with my engine and boat type?
  • What warranty do you give on the hull repair and the engine work?
  • Does this repair need a haul out, and is that included?

Red flags

  • Says a hull repair is done without showing the damage
  • Will not put the parts and the labor in writing
  • Recommends engine work without a compression or diagnostic test
  • Works on the fuel system without the right training or a written plan

What you can do yourself

You can keep the boat clean, check the bilge for water, look for loose or frayed wiring, and check the engine oil and coolant when the engine is cool. Do not work on the fuel system, fuel lines or the engine's electrical systems yourself, since fuel and fire are a serious risk. Hire a pro for hull damage, the steering and any engine repair.

Licenses and permits

A license is usually not required for boat repair, but marine and electrical rules vary by state and city. Check with your state or local licensing agency, and ask the shop to show its insurance and any training it holds.

Boat repair questions

How do I know if a hull repair is structural?

Ask the technician to check the frame, stringers and bulkheads near the damage. A crack that reaches structure needs a proper repair, not only a cosmetic fix.

Why does my boat run rough after a winter?

Fuel degradation, a dirty fuel filter and a weak battery are common causes after storage. A technician can test each one.

Can I work on my boat at my dock?

Some work can be done at a dock, but fuel, electrical and hull work often needs a haul out or a shop setting. Ask the technician what they need.
