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

The B-series is commonly relied upon for dependable starting with the combination of torque and modularity. Providing 45 ft-lbs of torque in a 17 lb package, the B-series starter is a workhorse. Depending on conditions, the starter cranks up to 18 liter (1098 cu. in.) engines which are common in the marine industry. B-Series Models: B1-09B1106-1A200, B1-09D2113-1A200, B1-10D2125-1A200, B1-10E2100-1A200, B1-11B1130-1A200, B1-11C2183-3A200, B1-12D2150-3A200, B2-10D2125-1A200, B2-12C2200-3A200
