I have 3 500EFIs, the port and center motor all act the same. Turn the key get a few beeps hear the electric fuel pump kick on, they crank and fire. My starboard has been doing something odd lately. First I don't get any audible tone when I turn the key, actually it never has since I've owned it. I do hear the fuel pump kick on, but lately when I turn the key to start I get nothing. No crank, no click, nothing. I have to turn the key back and try it again a few times to get it to actually crank. Could this be something in the ignition switch itself or something with the starter? I haven't looked into it much but will probably dig into this weekend since weather doesn't look to good. Battery checks out in case anyone was wondering. All my gauges responded too when I turn the key.

Thanks in advance.

My guess would be ignition switch. Easy to check with a volt meter.

Did some digging and the audible tone works fine going straight to 12V. For some reason I’m losing voltage through the switch. Not much but clearly enough to affect the audible tone and the solenoid for the starter.
