If you can hear the choke, you should also be able to hear the starter solenoid. If it isn't clicking when you hit start, I would start by checking the voltage to it. The positive line of the battery connects on one side and the other side continues to the starter. There will be two terminals on the front that power teh coil (or one if it uses the battery ground). Make sure you are getting voltage there when you turn the key to start. If you don't, trace it back. Which engine do you have, I probably have a wiring diagram.

See my other post for checking power to the solenoid. If you get power and it is not clicking and feeding power through, it is bad.

It is a 1975 model 50573b 50 hp outboard. I could really use that wiring diagram to make sure my rectifier is right and all the wires on the post on the side of the motor are right. Thanks

Took a piece of wire and touched the two hots that run from the starter to solenoid together on the solenoid and the starter spun and the motor started but will not start at key.what does this mean if i can start it this way but not with the key?

Re: 1975 evinrude will not start with key but with pull cord?

broken connection between solenoid coil terminal and battery. Could be anywhere along the way (neutral switch, key switch...). I'll get you a wiring diagram.

Can't seem to figure out how to add a picture to a private message so send me a private message with your email and I'll send it. The wiring diagram is for a Johnson but they are the same.

Is the fuse in the connector by the solenoid good?

Re: 1975 evinrude will not start with key but with pull cord?

Good suggestion on the fuse. It is located between the solenoid and the plug and feed the solenoid coil when the key is at start.

Hey, try pushing in the little white button on the neutral switch and try starting it then to eliminate that. If that doesnt work replace the starting solenoid. If u have a voltmeter keep checking for voltage all the way from keyswitch and follow the wires, see where your problem is.

Re: 1975 evinrude will start if the two hots at soleinod touched with a piece of wire

Yes i took apart the control box and the little neutral safety switch and tryed pushing that in and starting and nothing. is there a posabillity that little safey switch went bad? those little things are expensive. I bought 2 used solenoids yesterday off ebay for $5.00. the guy says there good so we will see.I will pm you now . Thanks guys! I will deff let you know what i find.

Sounds like the solenoid, starter and battery are ok. You've checked about all you can. Possibly a bad key switch. Check for voltage from the key switch to the solenoid when the key is turned to start.

Re: 1975 evinrude will start if the two hots at soleinod touched with a piece of wire

Yes the fuse is god. Had that problem before. If that little fuse blows in the line you i dont get power at all. When i turn the key to on position the choke works and tachometer zeros out. but just will not start.

Re: 1975 evinrude will start if the two hots at soleinod touched with a piece of wire

emdsapmgr let me ask you this. If i touched the wire on the solenoid that comes from the key switch to the hot on the solenoid to starter with the key on what should it do. Done this yesterday and nothing but then touched the two hots going to starter and she fired right up.

Re: 1975 evinrude will not start with key but with pull cord?

It's a simple system. When the key is turned there is 12v put to one small post on the solenoid. The other small post is a ground. It activates the solenoid and it starts. There is a neutral safety in the box and another at the motor that will open the circuit so it won't start in gear. check both neutral safeties. Also get an ohms or volt meter and check the switch.

Were is the one on the motor? I wasnt aware of one there?

Re: 1975 evinrude will not start with key but with pull cord?

Just looked around the cables on the motor coming from remote control and didn't see any kind of switch or button or any thing with wires on the cables. But i realized i been running it at half choke. The manual choke was half way allowing the electric choke to work. went to work the choke to see if i was getting power and it was just clicking due to the manual choke being all the way back at no choke not letting the electric choke close the carbs. This may be why the motor was running weird at low throttle and dieing in reverse unless floored in reverse? again another big lol

Re: 1975 evinrude will not start with key but with pull cord?

I pushed the nuetral safety switch in and out while turn the key and nothing. I wonder if the safety switch is bad if i disconnect the wires from the safety switch and twist them together if that would bypass the safety? might try this after the new solenoids come and install it.

Do you have a volt-ohm meter?
That will allow you to do a few simple tests that will help zero in on the problem.
Otherwise you will be changing parts on a trial and error basis.

Check for continuity of the solenoid primary ground. Meter set to "ohms", test leads go on 1) the negative solenoid primary terminal, 2) on a good engine ground point. Reading should be 0 ohms. Touch the two leads together to make sure that that reads 0 as a reference.
If it is OK, run a jumper from the positive battery terminal to the positive terminal of the solenoid primary. If the solenoid activates the starter, you can eliminate the solenoid as a problem.

Reread post #34. If the solenoid is OK, you need to see if you are getting 12V to the primary (+) solenoid terminal when the key is turned to the "activate starter" position.

The neutral switch at the motor should be somewhere close to where the throttle linkage connects in the motor. You really need to get a meter and follow the path as previous posts have described

Re: 1975 evinrude will start if the two hots at soleinod touched with a piece of wire

I touched the hot from battery on the solenoid to hot to starter on solenoid and it started? I am short on cash right now and cant afford a tester. mine is bad and will not read at the battery.I droped the whole wiring harness and traced the wires back everything looked good. there is no safety switch on the linkage on motor. so its ither my ignition switch or safety switch in control box. i noticed today when looking at safety switch in box the white button looked alittle bent at the tip and the back of the ignition switch looks pretty old. Can i put a push button on the solenoid with a wire running from the battery and one running from the starter hot on solenoid and start it that way? And drill a hole for the button on the lower cowling to avoid taking the hood off every time to start it? Money is the issue here for me. or does anyone know how to bypass this safety switch to see if this is the problem?
