Parts & spares
Search every parts catalogue at once
4,994 genuine Mitsubishi Heavy Industries (MHI) part numbers across all five marine parts catalogues we've digitised — S6A3, S6R, S6R2, S12R-MPTK and S16R. Search by part number or description and see every model that uses it in one result.
Hyphens, spacing and case don't matter, and an "MI" prefix (OPS's own part-number format) is handled automatically. Not sure which model your part belongs to, or can't find it here? Browse by model below, or send a parts enquiry with your engine serial number and we'll track it down.

Service kits across all models
The kits customers order routinely — overhaul gasket kits, oil seal kits, water pump repair kits, pump assy overhaul kits — pulled out from each model's full catalogue. Not every kit exists for every model; S6A3's catalogue, for example, lists no dedicated kit groups at all.

Parts for engines we service but don't sell new
These engines are already in service across Australia, New Zealand and the Pacific — some never had a Tier II-coded Australian variant, others are the older pre-Tier-II version of a model we still sell today. Either way, OPS holds and sources genuine parts for them.
Older or export-market codes of current models
