Time to plane may represent the most impressive performance aspect of this 28. Push the throttles forward, and the Luhrs fairly leaps up, leveling out in about four seconds - not bad for 260 hp diesels. Top speed at 4,200 rpm hit 35.6 mph, using 26.5 gph. At a cruising speed of 30 mph (3,600 rpm/72 percent load), that fuel consumption drops to just over 22 gph, providing a range of more than 350 miles. At idle speed (670 rpm) with both engines, we trolled along at 4 mph with an absolutely spotless wake. Boost that to 7 mph (1.5 gph), and the wake remains clean.
