How surveys describe it
Wording varies by surveyor. Illustrative examples (not quoted from any real survey):
- “Portable fire extinguishers are past 12 years from date of manufacture.”
- “Extinguisher gauge reads in the red.”
What it is
US Coast Guard rules require marine-type extinguishers. Disposable extinguishers are treated as expired 12 years after their manufacture date, and boats from model year 2018 on need 5-B or larger units.[1][2]
How serious it is
Cheap to fix, but it's a carriage requirement and a safety item: replace before you use the boat.
In our reports this usually lands under Fix. Your survey's details decide.
What it typically costs
| Scope | Estimated range |
|---|---|
| 1 item | $30–$90 |
| 2 items | $60–$180 |
| 3 items | $90–$270 |
These ranges combine typical parts costs of $30–$90 per item.[1][2]

Estimates to help you frame a conversation with a yard, not quotes. Real prices depend on the boat, the yard, access and what's found once work starts. Confirm with your surveyor or a qualified yard.
What to ask your surveyor or yard
- How many extinguishers does this boat need?
- Is there a fixed engine-room system, and is it in date?
