The Chaparral 227 SSX produced impressive performance during our test runs particularly in the hole shot times, averaging just 3.6 seconds -- very strong, considering she was powered by a single MerCruiser 250-hp sterndrive engine. Speed at WOT was 45.5 mph, while best cruise was at 2500 rpms and 19.0 mph, where she got 3.7 mpg for a maximum range of 149 statute miles with a 10% reserve.
