S12R-MPTAW
This exact configuration isn't sold new in Australia — Australian rules require new marine engines to meet IMO Tier II emissions requirements, and the S12R-MPTAW doesn't carry a Tier II rating. If you're running one, OPS still stocks genuine parts for it and can supply the current Australian Tier II S12R equivalent below.
