Dont know much about this engine as it belongs to my neighbor. What I do know is it is not getting any spark on any plug. This was brought on for no apparent reason and seems to have slowly gotten to this point. We dont know much about the wiring on this unit but did rule out the igintion by swapping port and starboard engines at the switch. Is there anyway to to bypass ECU? On my yammy there is a plug which bypasses for emergencies.<br />Any thoughts? Thanks
