Evinrude Zephyr, what to look for ?

[todd281]

I am going to look at a Zephyr this afternoon and would like any advise from the members on what to look for, or “tripping points” for these motors. I will check that it turns over and has decent compression . My concern is mostly with the coils, condensers, points. If I need them can they be had ? pricey? Need to contact the Pope ? Any replies appreciated .

No missing parts there are a lot of Zephyrs so buy a complete one. Coils can be found, Lightfour or Speedfour coils fit .

ok another aquasition, I now own one Zephyr

Zephyr ignition systems can get a bit finicky as one set of points fires two cylinders at the same time so they have to be really clean and gapped correctly. On this Zephyr I removed the points and condensers and used red Atom modules to replace them. Much easier starting and smoother running.

Wow, that looks like a nice clean set up for the point replacement. I did a quick search for “atom ignition modules” but it seems they went out of business around 2005 . does anyone know of a alternative to them?

I had mine running in the barrel after dark and the spark plug wires were arcing away under the magneto plate. It was quite a show. So check for cracked ignition wiring.
The gas tank is vented through the carb via a small copper line which is usually plugged. Quickest fix is to get a vented cap.

Using shorty spark plugs will also help prevent any arcing under the front cover.

I thought of using the shorter plug style . Am I correct that the replacement “shorty” would be a Champion CJ 6 or equivalent? And I am still wondering how to choose the right module for the pointless conversion? I see that there are many different kinds of Ignition Modules available but not to much info on how to choose the right one for a older outboard. They all seem to be listed for specific engine makes like; Briggs , or sometime it says “Fits most chainsaws” So how does one choose the right one when shopping for a Zephyr?

And now that I have pulled the flywheel I see that the previous owner has replaced the plug wires, they are the right solid core wires but I would like to make sure that he has them in the right order. Does someone know, which connection on the coils went to which plug? I also need to know if I should expect this to throw a 7/16 gap spark or is that wishful thinking? I do see a spark on all four wires but I am not sure about it being a good spark. thanks

IS there a marker on two wires is so these are the top plugs or pull the top plugs rotate motor until pistons are at top. Now check points the the ones that open when pistons are near the top are top points.. Now trace point wire to coil ..
