Marco

Marco marine equipment, not fashion

This page is about Marco, the Italian maker of marine pumps, horns and valves. If you were looking for Marc O'Polo clothing or the Marko outlet store in Hereford, this is not it.

Marco equipment is standard on many European yachts and workboats. When a yard changes spec or a distributor clears stock, the unused pumps and horns come to us, and you can buy them well under the dealer price.

What you find in our Marco outlet

Transfer and gear pumps

Self-priming gear pumps from the UP range, such as the UP6 and UP9, for diesel, oil and water transfer, plus impeller pumps like the UP1-M for bilge and fuel. Check the flow rate, voltage and the liquid the pump is rated for.

Oil changing systems

The OCS oil changing system with 6 valves, for changing engine and gearbox oil on board without draining by hand. Some UP6 pumps here are listed with the matching engine-maker part number, which helps when you replace an existing unit.

Air horns and electric horns

Compressor air horns from the PW series, double and single electric horns, and stainless steel horns like the EMX2. Horns are chosen by vessel length and required sound range, so check the rating against your boat.

Solenoid and fuel safety valves

12V and 24V solenoid valves in 1/4, 3/8 and 1/2 inch, several of them RINA certified, plus fuel safety valves for engine shutdown circuits.

Spare parts

Filter housing covers, hose sets, control units and protection caps for existing Marco installations.

What to check before you bid

• Voltage. 12V and 24V versions look the same.
• Thread and bore. For valves, match the connection size and orifice.
• Rating. Pumps are rated per liquid; a water pump is not a diesel pump.
• Certification. RINA approval is stated where it applies.
• Condition. Unused or used is stated per listing.
