Description
The 220V version of the Mermaid M16 Cool Only brings the same 16,500 BTU cooling-only platform to boats wired for that slightly different voltage standard rather than the more common US 230V — same heavy-duty stainless construction, same capacity, same footprint.
Key Features of the Mermaid M16 Cool Only (220V)
- No reverse cycle mechanism, meaning fewer components that can eventually need service
- Constructed on 304-18 gauge stainless steel, a heavier-duty spec than Mermaid’s compact units
- Soft start technology and variable speed blower reduce startup strain
- Mechanical freeze protection built into the redesigned control system
- Available in right, left, or top air discharge configurations

Why Choose the Mermaid M16 Cool Only (220V)
Electrically, this performs identically to the 230V Cool Only version at the same 12A running amperage — the voltage input is the real distinction, relevant mainly for boats built to or imported from markets using the 220V standard.
Confirm your vessel is genuinely wired for 220V rather than 230V before ordering, since the two aren’t always interchangeable depending on regional electrical conventions and existing onboard equipment.
What to Know Before Installing
- Confirm your electrical system’s actual voltage standard before ordering — 220V and 230V aren’t always interchangeable
- Pump is not included and must be sourced separately
- Plan for three discharge points: one 8″x6″ grill within 6 feet of the unit, plus two 4″ round vents
- Since this unit has no heating function, confirm it matches your climate needs before ordering

Mermaid M16 Cool Only FMS FAQ
How much does Mermaid M16 weigh?
Mermaid M16 weighs exactly 60 lbs net weight. This customized flat marine surface configuration removes heavy reverse-cycle plumbing, providing 16,500 BTU of high-capacity cooling performance while reducing overall structural weight on fast hulls. It avoids ballast complications across lightweight racing yachts during high-speed summer ocean navigation.
What duct size does this unit need?
Mermaid M16 requires a 5 inch duct ring size. This factory specification allows your high-velocity rotatable centrifugal blower assembly to discharge conditioned air freely, bypassing tight static pressure constraints in shallow overhead spaces and establishing rapid, balanced environmental temperature reductions across multi-outlet vessel ventilation runs.
Where should you install Mermaid M16?
Mermaid M16 is perfect for low-clearance storage berths and shallow salon seating blocks. Certified marine technicians typically mount this 220 Volt flat profile layout on performance motorboats up to forty-five feet, where its streamlined stainless steel mounting pan slides into tight companionway compartments easily.
