More speed usually equals more horsepower — and more money — but Stingray doesn’t believe in conventional wisdom. The 198LX is the latest in a line of runabouts that coax maximum stats out of minimum horsepower. In a driving rainstorm, I noted a quick 3.0-second time to plane, 7.4-second time to the 30 mph benchmark and 58.2 mph top speed from my test boat’s economical 220 hp MerCruiser 4.3 MPI and an optional 21-inch-pitch Laser II prop. In better conditions, Mercury techs recorded consistent 59s. What’s Stingray’s secret? Owner Al Fink, who foregoes conventional strakes in favor of overlapping planes, also borrows a notched transom design from speedy go-fasts. The overlap is like roof shingles, acting as lifting surfaces until the boat gets on plane, and spray releases after, providing a smoother flow of water to the prop. The transom design extends the hull surface all the way below the swim platform, and allows the drive to be mounted higher, reducing drag.
