This SX23 Premium Swingback is a convincing combination of Bennington quality and attention to detail, with a price that gives budget-minded boaters, and especially first-timers, true excellence without a huge payment. Fitted with a four-cylinder Yamaha F150 four-stroke outboard, the boat has performance and economy tied together at the hip. During testing, we recorded 38 mph at 5,900 rpm, swinging a 15-by-14.5-inch Yamaha Reliance three-blade stainless-steel propeller through 2:1 gearing. Minimum planing speed at 14.5 mph and 2,900 rpm gave the SX23 a slow cruise without plowing. Our best cruise speed, where the SX23 Premium Swingback proved most economical, occurred at 4,000 rpm and nearly 23 mph. At that speed, the F150 sipped fuel at 6.4 gallons per hour, garnering just under 3.7 mpg. Acceleration from a dead stop was brisk as we raced to 30 mph in just 7.7 seconds. This is a package with plenty of juice for watersports and big loads.
