An ad for the Flexidrive from a 1960 issue of Boating Magazine shows a unit that looks much like the one spotted at the boat show, without the sweeping, stingray-shaped anti-ventilation plate seen on the 1959 model. The Flexidrive appears in "what's new" reports in boating and mechanics magazines through the 1960s, with models usually mated to Ford gasoline engines and, in 1968, to a 60-hp Isuzu diesel engine. A 1968 report in Popular Mechanics magazine lists 15 sterndrive brands, including Muncie, Brennan, Chrysler, Eaton, Holman & Moody, OMC, Osco, and Stokes Marine, plus of course MerCruiser and Volvo Penta. Pages from a 1971 Muncie brochure reveal both the 500 series and the new "husky" 700 Series Flexidrive rated for up to 225 hp. By then, of course, MerCruiser was dominating the sterndrive field with a 50 percent market share that crushed smaller drive builders like Muncie.
