Evinrude 4HP 1976- 4636

What is a ballpark figure on the output voltage to the plugs for this little popper?? I've replaced cracked coils and installed new points and condensers. The magnets are strong. I wouldn't be asking if the info was in the service manual. <br /><br />Thanks in advance for any info.

Just to round the figure out.... about 50,000v

Yikes! I had no idea it would/could get that high. Thanks for the info, now I'll have to re-think my choices for plug wires.

Use regular metallic core 7MM spark plug wire. Do NOT use graphite core automotive type wire...<br />- Scott

Seems finding stranded copper (steel clad copper) wire is harder these days. I can remember when most cars used this stuff. Since I'm not too concerned with EMI or RFI, I'll stick with the copper variety. The factory wires have a coil of spring steel with the spike to terminate the plug end. Since my main line is electronics, is there a solder type connector replacement?? Seems soldering the plug end would reduce any resistance at that connection. All I have seen are the crimp types and the aforementioned 'spring coil"

Soldering won't hurt anything, but I feel it's unnecessary. I like to trim the last 1/8" of insulation off the wire and splay the core out so that it increases the contact area against the sparky connector...<br />Your old style ignition won't overcome the added resistance of using a graphite core wire, so you MUST use metallic core, regardless of EMI or RFI preference..<br />- Scott
