Competitive Yanmar sourcing — OEM and alternative.
Yanmar OEM parts are available through official channels, but lead times and pricing can be constraining. Vessel Core provides both genuine OEM supply and verified alternative sourcing that maintains technical specification — giving technical managers a choice based on situation, budget, and urgency.
OEM or Alternative — Your Choice
For class-surveyed overhauls or manufacturer-warranty situations, we supply genuine Yanmar OEM parts. For running maintenance and planned spares, verified alternative components are available at competitive prices without compromising specification.
Full Model Range Coverage
From the compact 6EY18 auxiliary to the high-output 6AYL and 6N21 engines, we cover the full Yanmar commercial marine range. Generator set configurations and propulsion auxiliary variants are both in scope.
Lead Time Confirmed at RFQ Stage
Lead time, availability and freight options are confirmed at RFQ stage based on part specification, approval requirements, vessel ETA and destination port.
Technical Part Identification
Missing Yanmar part numbers? We identify correct components from engine model, serial number, build year, and component description or photographs. No incomplete RFQ is turned away — we source from available technical data.
Worldwide Port Delivery
Yanmar parts are delivered to your vessel's port of call — not just Baltic or European ports. From Singapore to Fujairah to Rotterdam, we coordinate supply against your vessel schedule and confirm delivery via port agent or ship chandler.
Urgent Breakdown Priority
Generator set failures and auxiliary engine breakdowns receive priority RFQ handling. Urgent Yanmar RFQs trigger priority sourcing review and freight coordination based on vessel urgency, part availability and port timing.
Yanmar parts — common questions
Do you supply both OEM and alternative parts for Yanmar marine engines?
Yes. We source genuine Yanmar OEM parts and verified quality alternative components for Yanmar 6EY, 6AYL, 6N, 6HAL, and 6MAL series marine engines. Alternative parts are available where quality and specification match permits, typically offering budget control compared to OEM list pricing while maintaining the technical requirements of the engine.
What Yanmar engine models do you cover?
We cover the main Yanmar commercial marine engine series including the 6EY18, 6EY22, 6AYL-ET, 6AYL-HT, 6N18, 6N21, 6HAL-DT, and 6MAL-HT. If your engine model is not listed, provide the nameplate designation and we will confirm parts availability and sourcing options.
How quickly can Yanmar spare parts be delivered?
Lead time and freight options are confirmed at RFQ stage based on part availability, vessel ETA, destination port and urgency level.
Can you identify Yanmar parts if I only have the engine model and a description?
Yes. Our technical procurement team can identify the correct Yanmar components from the engine model designation, serial number, build year, and part description. Photographs of the installed component or the engine nameplate are also accepted as reference material to confirm the correct specification before sourcing.
