94 Spectrum, Mercruiser Alpha One 135 hp.<br /><br />I'm having a problem with the ignition. Many times when I turn the key, all I hear is a single click. When I try a number of times, I'll eventually get it to turn over. <br /><br />At first, I thought maybe it was because the ignition module wasn't quite tight in the boat console, but I tightened the nuts so that it doesn't twist when I turn the key, and I get the same thing. I haven't experienced the point where I can't get it to turn over eventually, but am afraid I'm going to get stuck somewhere.<br /><br />Battery is fine. Solenoid problem? Should I replace the ignition? Any help would be appreciated. Thanks.
