How did it run for you last season ?----The orange wires from switch box ( powerpack ) going to the top coils are what color ?----Correct prop fitted to suit the boat ?

Does spark jump a gap of 7/16" on all leads on a test device ?---Compression test results are recent ?---Are you pushing the key in while cranking for the cold starting ?----- -I can not see, hear or feel your motor.-----You must do inspection / testing and report.
