Since 1996 Orbitals direct injection technology has lead the
way as the solution to emissions compliance for outboards and personal
watercraft. In addition to lower emissions, products equipped with
OCP offer reduced smoke levels, improved fuel economy, smooth
running, improved throttle response and offer consistent reliable
starting under any conditions.
The marine sector, and the 2-stroke engines that have long dominated
this market, were challenged by emissions compliance requirements
introduced in the late 1990s. These requirements include:

- United States EPA rulings for outboards
and PWCs
- Progressive emissions reduction
starting in 1998
- 70% reduction by the year 2006.
- California Air Resources Board (CARB)
accelerated requirements requiring
- 70% emissions reduction in 2001
- 77% in 2004
- 90% in 2008
OCP equipped 2-stroke engines, such
as Mercurys OptiMax 3-Star rating models, demonstrated
the capability to meet these low emissions levels. Today, several
manufacturers have adopted OCP technology on their marine
products with others having evaluated its applicability to related
markets such as snowmobile and all-terrain vehicles. OCP technology
has also been applied to 4s and heavy fuel applications to address
the particular challenges of this particular product group.
