Mercury Racing reveals the new 60 APX

Low-Emission Four-Stroke Power for UIM Formula 4 Racing: Mercury Racing today unveiled the 60 APX outboard engine as the latest addition to its portfolio of pure Apex engines for closed-circuit racing. The 60 APX was unveiled at the Dubai International Boat Show at Dubai Harbor, United Arab Emirates.

“Mercury Racing is excited to support the sustainable future of circuit racing with the fuel-efficient four-stroke 60 APX,” said Jeff Broman, Director of Mercury Racing. “We have designed this engine to deliver high performance with minimal maintenance throughout the season, thereby reducing the cost of participation in entry classes for professional tunnel boat racing.”

The Mercury Racing 60 APX is a heavy-duty racing engine designed specifically to power the tunnel-hulled catamarans of the UIM Formula 4 class. The Formula 4s class features composite, cockpit-equipped boats that measure 3.9 meters in length with a minimum weight with driver of 360 kg. Maximum speed is about 120 km/h in the straight sections of the course. The class is intended for young racers who start in closed tunnel boats before moving up to the faster boats in the Formula 2 and Formula 1 classes. The Formula 4s class is very popular in Europe and the Middle East.

Technical specifications of the 60 APX

The 60 APX’s 60-horsepower, 995cc four-cylinder powerplant is based on the reliable Mercury 60 FourStroke outboard with electronic fuel injection. The rev limit at full load is increased to 6000-6400 rpm, and the engine features a 15-inch center section and wingplates for the side-steering system used on racing tunnel boats. The 60 APX model uses a standard Mercury foot with underwater exhaust and a 1.82:1 gear ratio. The dry weight is 112 kg. The engine develops maximum power using 90 RON (87 octane) economy gasoline. The new Mercury Racing Apex graphics match those of the 4.6-liter V8 360 APX and 3.4-liter V6 200 APX four-stroke racing engines.
