Oh are you human? I have a 65ph Evinrude 1973. It seems tookay, I have a 65ph Evinrude 1973. It seems to get intermittent spark, rectifier seems to have exposed wirring, have not replaced yet but tested with wires removed and no difference, Ive pulled the flywheel to inspect the stator and it was shorted and burnt up... Replaced the stator, spark seems intermittent still after changing stator, it will start for about 5 second if lucky then die, seems like fuel delivery issue, but in reality it is flooding and the spark plugs are drowning in fuel, if I pull the plugs and clean them it typically tries to start immediately... Could be compression issue or ignition issue and maybe the spark is cutting out. If I check with the spark tester I get intermittent spark, sometimes it will try to fire when I have a plug removed and a the tester installed. I have tried pulling the spark wires out of the coils and cleaning the pins NOTE (pins were rusty and likely causing poor connection) After cleaning It seems run better but still only 5 seconds average until plugs are flooded. I checked compression, but my gauge seems to not be working properly as it does not build pressure, rather it pulses with the compression cycles, appeared to be 60-90 psi with my faulty gauge, NOTE (gauge goes from 0-90 psi per stroke so an average of the highest pressure is being recorded. at least one coils seems to be cracked, but does not appear to be catastrophic, possibly all I need is to replace the coils. Any Help is appreciated … read more
