    Thanks for being BLUNT, I just went and reread what was stated about driver coil and coil packs that go to the spark plug. To be BLUNT I wrote it down incorrect so you were right to tell me. But I do understand what the process is. Driver coil sends voltage to the ignition coil that steps it...

    i watched some videos to see about the suction or pressure depends on how you look at it, but most say 1lb, the problem is unless you hook a gage to the line and add a T so fuel can still go to motor when running. you wont feel it if you put your finger over the hole? so out of the three motors...

    1974 Evinrude 25hp wont run.

    I should correct my self. So from what I have read and looked up the fuel pumps that are on theses types of motors only use the pulse from The crank case that makes the diafram pulse.
