I've got a 1976 Johnson on a 1976 13 foot Whaler that just stops running as if the swiitch was turned off. The motor is in good shape otherwise. Appears to be electrical problem -after a few minutes the motor will crank and run well for a long time. May just be a loose wire. coil, power pack?? Any suggestions will be apprcicated.
Thanks,

Doesn't sound like coil if cranks and runs.definitely not fuel prob if it's just cutting of without any kind of hiccups. In my humble opinion it sounds like a intermittent voltage issue possible stator/ rectifier but in no way am I even close to outboard mechanic.

If it appears the switch was turned off as you suggested it may be just that simple. Try a new ignition switch. Short money and very easy to change. I always start with the simplest things first.

I totally agree with Ice cop its a niggly fault .Sometimes it is simply a loose connection on the ignition switch and or at the distributor end via the ignition coil. Insure the connections are tight.Through period of time a loose connection becomes hot and starts arcing and due to expantion, becomes softer and eventually the connection gets from bad to worse. Intermittent ! I hope it will give something to chew on and help you. Good luck!

Thanks for your reply--I'm with you as I'm not much of a mechanic either but will look at the stator/rectifier

No problem, I just believe you start simple, and cheap. Then if it gets beyond your level of expertise(whatever that level may be) ask for help from someone you trust, easy for a stranger to say pull this apart or try that and all you end up doing is messing up something else. Keep us posted on what you find.
Good luck

I wouldn't go replacing parts cheap or not without checking first connections, power, ohms, etc. Even a switch can be jumped first without spending money.
