Atomized fuel is injected directly into each combustion chamber, backed by a precise charge of compressed air, and the fuel / air mixture is directed toward the spark plug by a uniquely shaped piston. The result is more-complete combustion for outstanding economy and smoke-free emissions.
More than a decade of reliable Mercury® OptiMax® performance is testimony to a great design. Low-pressure Direct Fuel Injection (DFI) delivery, corrosion-resistant alloys and finishes, and rugged components keep Mercury OptiMax outboards on the water, season upon season.
No outboard in its class weighs less than the Mercury® 250hp OptiMax®. That helps create amazing hole-shot acceleration, increased top speed and overall efficiency. Its compact 60-degree V6 engine delivers brawn without the bulk.
A 60-amp (756-watt) belt-driven alternator keeps batteries charged to power electronics, lights, livewells and audio equipment.
