Why MARS

Buying power equipment from China, made simple

Instead of dealing with a dozen factories, you get one accountable supplier with engineering support and documented quality control.

One-stop sourcing

Consolidate diesel engines, gearboxes, outboards, watercraft, liferafts and spare parts through one supplier who knows how they fit together on a vessel or in a fleet.

Engineering-led matching

Engine power and speed, gearbox reduction ratio, rated thrust, flange and coupling type and cooling are confirmed before order — so the package installs without surprises.

Inspection & documentation

Machinery is tested before dispatch. You receive an outgoing-inspection report and video; conformity, performance-test and packing records are available for tenders.

Multi-brand coverage

SDEC, Weichai & Baudouin, Yuchai, Cummins-type, Isuzu-type, Doosan, JMC, Yangchai, SAIC MAXUS, Hangzhou Advance, Fada, Mercury, Suzuki and BRP Sea-Doo.

Export-ready supply

New products with warranty, sea-worthy wooden-box packing, common models in stock and built-to-order models typically within about 20 working days.

After-sales support

Spare-parts packages, technical documentation and remote support for installation and commissioning — plus spares kits built from your engine list.
