M4: The M4 rating is for marine propulsion applications that typically operate between
1,000-3,000 hours per year and have load factors below 40 percent. This rating is for
12 45 applications that use full power no more than 1 hour out of each 12 hours of operation.
The remaining time of operation is at or below cruising speed.
