The new C310 outperforms every other Pursuit center console that has gone before, thanks to a deeper deadrise carried farther forward, a sharper entry and a wider beam. A pair of Yamaha 250 hp four-strokes lifted us onto plane in a scant three seconds. Though factory specs claim a displacement of 8,300 pounds, I figured that with three of us aboard, plus fuel, water, gear, etc., our actual weight came closer to 11,000. Nonetheless, I managed to squeeze 53.4 mph out of the 310 at 5,700 rpm, while the Yamaha Command Link fuel gauges claimed a twin-engine burn of 44 gph. A common 35 mph cruise at 4,300 rpm used 22.8 gph. I found the most fuel-efficient cruising speed - 25.6 mph - used 14.5 gph for 1.77 mpg and a range of 415 miles (figuring 90 percent usable fuel).
