Mercury Racing has introduced the 60 APX outboard motor, the latest addition to its range of Apex outboards designed for closed-course circuit racing.
The Mercury Racing 60 APX is a competition motor designed to power UIM Formula 4s class catamaran tunnel hull boats.
“Mercury Racing is excited to support the sustainable future of circuit competition with the low-emission four-stroke 60 APX model,” said Jeff Broman, director, Mercury Racing. “We’ve designed this motor to deliver strong performance with minimal maintenance over the course of a full season, reducing the cost of participation in the entry classes for professional tunnel boat competition.”
The 60hp, 995cc 60 APX four-cylinder powerhead is based on the Mercury 60 Four Stroke outboard with electronic fuel injection.
The Formula 4s class features composite, driver capsule-equipped boats measuring 3.9m in length with a minimum weight with driver of 360kg. The top speed of the engine is around 75mph.
The class is intended for young racers starting out in enclosed tunnel boats before they step up to faster Formula 2 and Formula 1 boats. The Formula 4s class is very popular across Europe and the Middle East.
The 60 APX model uses a stock Mercury gearcase with underwater exhaust and a 1.82:1 gear ratio.
