Motor Fresh oil and fuel tank great 3 trips, while cruising motor quits as low oil pressure alarm sounded , so checking oil perfect re started no alarms cruising to shore motor quits won't start.
Dry land check for spark none, disconnected black and yellow kill switch wire from remote no spark.
ground out oil pressure switch no change
Pulled flywheel to inspect timing marks and any belt damage all marks perfect at TDC☹️
SO tested coil pack ohm.meter looks ok, will plug in new CDI box Major concern over low COMPRESSION but will perform a leak down test next?
