One partner for the whole engine room
Mixed fleets run mixed engines — and chasing a different supplier for every brand wastes time when a vessel is in port. IWH is a single point of contact for Cummins, Caterpillar, Weichai & Baudouin, Yanmar, MAN and MTU marine parts.
We source by part number, consolidate across brands at our Istanbul hub and ship with clean export documents to CIS, the Middle East and worldwide — genuine, OEM-equivalent and verified aftermarket, confirmed before you commit.
