Marine AC Raw-Water Pump Replacement & Rebuild
When the marine AC stops cooling, the seawater pump is the #1 culprit on Treasure Coast vessels. Maritime Air Co. swaps March, Cruisair, and Headhunter raw-water pumps dockside — usually same-day — with strainer service, hose inspection, and full system commissioning included.

Why Maritime Air Co.
What You Get With Our Marine Water Pump Replacement Service
Same-Day Pump Swap
We stock the most common March MC and Cruisair raw-water pumps on the truck for same-day dockside replacement.
All Major Brands
March, Cruisair, Headhunter, Webasto, Jabsco, Sherwood, and aftermarket cupronickel-impeller pumps.
Strainer & Hose Service
Every pump swap includes raw-water strainer cleanout, hose inspection, and seacock check — the cheap parts that kill new pumps.
Rebuild Option
Where economical, we rebuild instead of replace — new seals, impellers, and end-bell hardware to OEM spec.
Flow Verification
We measure raw-water flow before sign-off so you know the new pump is moving the GPM the system needs.
Coil Health Check
Most failed pumps run with a scaled condenser coil. We inspect — and recommend a Barnacle Buster treatment if needed — to protect the new pump.

FAQ
Marine Water Pump Replacement Questions, Answered
How do I know my marine AC pump is bad?+
Symptoms include warm air at the vents, high head pressure, pump running but no seawater discharge at the through-hull, or pump motor humming without spinning. Most often the impeller has failed or scaling has seized the volute.
Can you replace my pump dockside?+
Yes — we run dockside pump swaps at every Treasure Coast marina. Most jobs complete in 1–2 hours including strainer service and flow verification.
What does a marine AC pump replacement cost?+
Parts run $250–$600 depending on brand and GPM rating. Labor for a standard dockside swap with strainer service is typically 1–2 hours. We quote in writing before starting.
How long should a marine AC pump last?+
5–8 years with annual maintenance and clean seawater strainers. Pumps fail early when strainers clog, when scale builds in the coil, or when the vessel sits unused for long periods.
