New Part Numbers Designate Crankshaft Use
Usage:
D398, D399 Engines
Two new part numbers are used to designate crankshaft usage in D398 and D399 Engines. No changes have been made to the crankshafts. Only the part numbers were changed to designate those crankshafts which have been given additional testing to meet the Marine Society certification specifications. Use the chart to order the correct crankshaft for your engine requirements.
