can someone tell me what would cause my rpm gauge to bounce all over the place... sometimes it works fine but most the time is all over the place. this is a 1997 evinrude intruder 150hp. thanks
Happens on my boat as well. Not sure you can do anything about it. Seems I read that response from a boater with the same problem. The guy explained why it happens but I can't remember his answer. Sorry I'm not much help. I just quit worrying about it on my boat. Like you said....sometimes it works. Sometimes it don't.
