formula - mercury engines

The latest and greatest Mercury duo prop, 2-gear, naturally aspirated, 12V 7.6 L 600-hp engine x2 vs. Mercury Racing's single prop, 1 gear, supercharged, 8V 4.6L 450-hp engine x3. Which rig is fastest, has the longest range, gets on plane at the lowest RPM and has the lowest fuel consumption? We have tested them both — see the results.

Battle of the Mercury Titans

It is fitting that the two most powerful engine platforms that Mercury produces should square off on the transoms of Formula's 380 SSC, the best-selling supersport crossover in the builder's SSC line. Further, this exquisite and luxurious boat incorporates virtually all of the functionality needed in a boat that can do almost anything.

The two boats we tested were similar enough to make this a very good "apples-to-apples" test between the two rigs. Both engine packages are remarkable for their own reasons.
