Re: finding ignition system for '70 40HP Johnson
<br /><br />Here's a schematic that will work. The Ignition on these didn't change for a couple more years after yours.<br /><br />All the parts are available right here from Iboats, or from your local NAPA store. <br />Coils - 18-5181<br />Points and condensors are also available, but they are usually ok, the points may need to be cleaned and re-gapped to .020".<br />The whole lot shouldn't cost you more than about $50.00
