A V8 MerCruiser would be 4 pulses

4 strokes fire every once every two rotations so divide number of cylinders by 2

2 Strokes fire once every rotation so number of cylinders equals number of pulses

Outboards usually go off the number of poles in the stater, I think OMC is six, not sure about any others.
