Questions To Ask A Marine Workshop Before You Book

Ask these before the job starts. Every one of them is harder to ask afterwards.

About the diagnosis

What exactly did you test, and what were the readings? A diagnosis backed by numbers — compression, pressures, temperatures, oil analysis — is different from an opinion.

What else could produce this symptom, and how did you rule those out? The answer tells you whether they diagnosed or guessed.

If this fix does not solve it, what is the next step and who pays for the first attempt? Agree this in advance, not after.

About the quote

Is this a fixed price or an estimate?

What is explicitly excluded? Parts at trade or retail? Consumables? Travel? Crane or haul-out? Disposal?

What happens if you find more once it is open? Ask for a dollar threshold above which they must call you before continuing.

What is the labour rate, and is there a minimum call-out?

Do you charge for diagnostic time separately, and is it credited against the repair if I proceed?

About parts

Genuine, aftermarket or reconditioned? All three are legitimate. You should know which you are buying.

Are the parts in stock, and if not, what is the lead time? Parts availability drives most marine job delays.

Do the parts carry their own warranty, and for how long?

Can I have the old parts back? A reasonable request, and a useful one.

About the work

Who will actually do it — and will it be the same person throughout?

When will you start, and when will it be finished? Get both. “We’ll get to it” is how a boat spends six weeks on the hardstand.

Will the boat be usable in between?

Will you road-test or sea-trial it afterwards? For anything affecting cooling, fuel delivery or the drivetrain, the job is not finished until it has run under load.

About accountability

What warranty applies to your labour?

Is that warranty transferable if I sell the boat?

Will I get a written report of what was found and done? This is what protects your resale value and your consumer law position.

Are you insured, and are you accredited to work in my marina?

After the job

Ask for:

  • An itemised invoice showing parts and labour separately
  • The written report of findings
  • Any test results, before and after
  • The old parts, if you asked for them
  • A note of what they recommend watching or doing next

File all of it. On resale, a documented service history is worth real money, and in a dispute it is your evidence.

Frequently asked questions

Is it rude to ask for a fixed price? No. It is reasonable for defined work like a service. For diagnostic and internal work an estimate with an agreed call-back threshold is the fair structure.

Should I supply my own parts? You can, and it sometimes saves money, but most workshops will not warrant labour on parts they did not supply.

Can I ask for the old parts back? Yes, and it is a normal request. Ask before the job, not after.

How long should a quote be valid? Ask. Parts prices move, and a quote should state its validity period.

What if the final bill is much higher than the quote? Raise it immediately and in writing. An agreed call-back threshold, set before the work started, is your best protection — see our guide to repair rights.
