Replacing Regular Spark Plug Wires<br />(J. Reeves)<br /><br />If you also need the spark plug boots and the spring terminals that connect to the spark plugs, purchase them from your local dealership (OMC Part #581027). This includes one boot and one spring connector. Price is about $3.25ea.<br /><br />Purchase whatever amount of spark plug wire you need. Be sure to purchase the kind that has a steel twisted wire leading through the center of it....... not the carbon type plug wire that many automobiles now use.<br /><br />Using your old plug wire, cut the new wire to a length about 3/4" to 1" longer. If you have no old plug wire, just make sure that the wire is longer than you'll need as you can trim the other end later.<br /><br />The rubber boot, spark plug end.... With the wire cut to the length required, trim back 1/4" insulation again but do not solder tint the wires. Simply fan out the wires and fold them back against the insulation, cutting the excess off as explained above. Holding the spring wire terminal, estimate where the prong should be inserted so that the spring will be flush against the exposed wire. Hold the spring terminal away from the wires end (sideways) and insert the prong into the insulation and into the center wire, then swing the spring terminal in front of the exposed wire portion (makes a tight fit for continuity purposes).<br /><br />Spraying the inner portion of the boot where the wire will insert with a small amount of WD40 makes the installation of the wire a easy project. That's it.... you're done.

making spark plug wires

can I make my own plug wires? I just need one wire, but would like to replace them all. My friend says no, you must buy them, but I seem to remember being able to make them cheaper and better? Am I wrong? Have a 85 sea drive. (all the outboard places say the same thing here..."heard of them, but never really seen one!"

Re: making spark plug wires

I make replacement plug wires using an NGK spark plug connector (bakelite style) commonly used on motorcycles. These terminals have a resistor built into them which can and must be removed. The plug wire is captured by a screw arrangement. The coil end of the wire can use conventional (but good quality terminals) available at farm and auto stores. You end up with a very high quality wire that should last the life of the engine. I'm most familiar with OMC but the fit on the plug is superb.

You must remove resistor as Upinsmoke says'<br />Took me 4 hrs and a bung knee to find that out on my motorbike.they do go bad.

If you have trouble finding solid core wire, check with the local lawn/tractor repair shop. Small engines take a non-resistor solid wire.<br /><br />Mark

A Johnson/Evinrude dealer should have the Packard 440 solid core wire on a spool in stock to cut off whatever you need. The plug boot and the coil boot is a different length.<br /><br />You can also buy the plug wire kit that has the sparkplug connector and the coil connector boots and a lenth of wire. It also includes a packet of Triple Guard grease for corrosion protection.<br /><br />For most common parts, the SeaDrive uses the same as the equivalent outboard version.
