Inside the inlet, I put the Venture 39 though its paces. Turning Yamaha Saltwater Series II 21-inch-pitch, three-blade stainless-steel propellers, the triple F350s vaulted the boat to plane in 4.5 seconds. It reached 30 mph in 9.5 seconds, en route to a top speed of 63.4 mph at 6,100 rpm, where the engines burned 100 gallons per hour for 0.63 mpg.
I found the optimal cruising speed at 34.6 mph (3,500 rpm), where the 39 achieved 1 mpg based on a burn rate of 34.5 gallons per hour. While this is slightly less efficient than the 1.02 mpg at 26.5 mph and 3,000 rpm I measured, the 39 seemed to feel happier at the higher speed. Either way, you can expect a maximum cruising range of 530 miles based on the 530-gallon fuel capacity.
