1966 Johnson SuperSea Horse 60hp - rebuild help sought

[jonny834]

Hi<br /><br />I have inherited this johnson outboard and for sentimental reasons would like to get working again. The compression is good, waterways clear and spins nicely on battery. So I think there might be a chance of restoring this engine.<br /><br />However there is no spark, at least resting the plug on the engine block shows no spark on turning over. I have cleaned and reset the contact breakers, the rotor arm and the ditributor cap. The ht lead tops on the plugs look filthy and rusted and I'm not sure the stop switch on the top of the magneto works.<br /><br />I'm hoping you guys out there may be able to offer some advice at least as far as getting a spark.<br /><br />Any thoughts?????<br /><br />Thanks

Don't know your engine but some general possibilities are Clean up HT lead terminals. Set timing. New spark plugs. Replace condensor.

The best advice I can give you is to get an OEM manual. ebay may have one or you can order one. Will make troubleshooting and repairs so much easier.

jonny, the switch on top of the magneto interrupts the current to the starter, when the motor is in gear, as a safety feature. It has no effect on the spark. There should be a black wire on the distributor which is the killer wire. This is grounded at when the ignition switch is off, to kill the spark. I would disconnect it for now. If you remove the distributor drive belt, and spin the distributor by hand, you should be able to generate spark without using the starter. Also, you need to gap the two sets of points. There are timing marks 180 degrees apart on the distributor body and pulley. Also, the condenser sometimes goes bad. Also, check the coil for cracks. Buy one at a junk yard if yours is bad.

Further testing has revealed that the coil is shorting across the laminations, so i'm told. So the problem now is I need a new coil. I have all but exhausted potential suppliers I can find. Can anyone help with sourcing this???<br /><br />Jonny

I had the same problem with my '67 Evinrude 60HP V4.<br /><br />It's been running a Bosch standard 12V car coil for the past couple of years. Runs fine. Cost a fraction of the genuine part.

For what it's worth, I own the same motor and have had great help form this forum. The advise so far is correct and as it happened to me as well the last thing I needed to change was my coil. I had the original one on my engine. I went to my local guy, I hope this is ok to do. Please edit if it not.<br />Albany Marine Supply<br />518-434-4421<br />ask for Tom<br />This guy knows about engines like ours. He just might have one for you. <br />Good luck

I got head and flywheel for my '67 Rude 40 from rerun parts on ebay, quite pleased with goods.
