Because the OptiMax jet drive engines have no gear case or propeller extending below the hull, they pass over obstructions that could limit a conventional propeller-driven outboard engine.
Compared to competitive four-stroke jet drive outboards in their class, these new two-stroke Direct Injected OptiMax offerings feature an excellent power-to-weight ratio, which make them ideal for shallow-water running conditions typical in jet applications.
The 1.5L OptiMax Jet 80 outboard engine is based on the 115 hp OptiMax and has a three-star CARB rating. The 2.5L OptiMax Jet 110 outboard engine is based on the 150 hp OptiMax and has a two-star CARB rating.
The OptiMax Jet 80 and OptiMax Jet 110 outboard engines are shipped “jet-ready” with no gear case or jet pump. Dealers and original equipment manufacturers (OEMs) simply order the appropriate jet pump and install it on-site.
The OptiMax jet drive engines utilize a patented XK 360 aluminum alloy with low copper content. In combination with a unique, multi-step painting process, the OptiMax Jet 80 and OptiMax Jet 110 provide industry-leading corrosion protection. All exposed fasteners, shafts and impellers are stainless steel, and multiple self-sacrificing anodes are used to further protect the engine. Both models are backed by an industry-leading three-year corrosion failure warranty.
In 2008, Mercury Marine’s OptiMax engine was ranked "Highest in Customer Satisfaction with Two-Stroke Outboard Engines" by J.D. Power and Associates for the third consecutive year.
The OptiMax Jet 80 and OptiMax Jet 110 outboard engines will be manufactured at Mercury Marine’s headquarter facilities in Fond du Lac, Wis. Both models are available for immediate order.
