    73 Evinrude 3 cyl 65hp runs eratically

    This motor on my son-in-laws boat is the same as mine on my Silverline. Problem is, his seems to be running on two cylinders and low on power and at times the third cylinder seems to kick in and it takes off, then kicks out again with the loss of power. I have the book and the peak reading...

I have no spark when the engine is hot or cold. I don't think it is the power pack.<br />Can anyone point me in the...
