Mercury Marine launched their latest 175hp, 200hp, and 225hp four-stroke outboards at the Miami International Boat Show in Florida last week.


“This new platform will position Mercury to advance product leadership in the 175-225hp outboard category, and deliver across the board on consumer needs,” said John Pfeifer, Mercury Marine president. “These new outboards address applications across recreational and commercial applications, strengthen our core product lineup by building off the success of our recent programs and delivering on the requirements of our global customers.”

The engine uses a naturally aspirated power head coupled with already existing and proven mid-section and drive-system designs. They offer both mechanical or digital controls and hydraulic or power steering. That iconic black cowling is also available in several shades of white with interchangeable panels in blue, red, grey and silver that run down the centre rear of the cowling. Personally I prefer the black.

Mercury has focussed on a unique design with plenty of features built into the new 3.4 litre V6 platform. They certainly are eye-catching with claims by Mercury that the new four-stroke engine is the lightest in its class. It weighs a mere 215 kilograms and will offer a far superior power to weight ratio than its competitors with more torque coming from the 3.4L engine.

The new cowling shape has allowed the addition of a service door providing easy oil tank access without having to strip down the cowling itself. The alternator also pumps out 20 amps at 650 rpm which should keep even the most electronics heavy boat owner happy.

The engine combines a host of features making it more efficient too. It is capable of analysing performance and adjusting the fuel mixture to deliver the best possible efficiency. It also runs specifically designed bearings and oil flows to minimize friction and the hydrodynamic gearcase shape reduces drag and delivers more stable high-speed performance.

Considering the frequency of multi-engine installations, Mercury also cater for that with the narrow, 64-degree bank angle and single-point cowl latch system enabling a tighter fit to the engine block. This makes the engine compact allowing multi-engine installations on a wider range of boats.
