Marine M1
For marine propulsion applications that may operate up to 24 hours per day at uninterrupted full power. These applications typically operate over 3000 hours per year and have load factors over 65%. The M1 rating is the ISO 8665 "standard power" rating and the SAE J1228 "crankshaft power" rating.

Marine M2
For marine propulsion applications that operate up to 3000 hours per year and have load factors up to 65%. This rating is for applications that are in continuous use, and use full power for no more than 16 hours out of each 24 hours of operation. The remaining time of operation must be at cruising speeds.

Marine M3
For marine propulsion applications that operate up to 2000 hours per year and have load factors up to 50%. This rating is for applications that use full power for no more than four hours out of each 12 hours of operation. The remaining time of operation must be at cruising speeds.

Marine M4
For marine propulsion applications that operate up to 800 hours per year and have load factors below 40%. This rating is for applications that use full power for no more than one hour out of each 12 hours of operation. The remaining time of operation must be at cruising speeds.

Marine M5
For marine propulsion applications that operate 300 hours and less per year and have load factors below 35%. This rating is for applications that use full power for no more than 30 minutes out of each 8 hours of operation and do not operate for the remaining 16 hours of the day.
