A-SERIES (CMO)
The A-series is not to be underestimated. Although small and extremely light (11 lbs), this starter packs a punch with 15 ft-lbs of torque and the ability to turn at 7000 RPM. This translates into an extremely fast engine starting up to 9 liters (549 cu. in.). These smaller engines are common on lifeboats, which is a prime example when fast starting is paramount. A-Series Models: A1-09B1106-TJ096, A1-09B1106-TR114-K, A1-12D2150-1A200, A1-12D2150-3A200, A1-13A1128-T0094
