    Optimax 150hp S.N 1B274973

    My engine is blowing the ignition fuse while running intermittently. I replace it and it works for awhile then it will blow again. I assume it is a ignition coil going bad. Is there any way to tell which one? Any help is appreciated

    Found the positive wire going to ignition coil #2 chaffed and touching metal. Pretty sure this may be the cause. Going to take the boat out this week and see if I get the missing and hopefully it don't pop the fuse again.
