S6B3-MPTA

This exact configuration isn't sold new in Australia — Australian rules require new marine engines to meet IMO Tier II emissions requirements, and the S6B3-MPTA 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 S6B3 equivalent below.
