Ed I will try to tell you what I know about these 4 banger rudes.  Post war models are usually 4404 model number.  I have two of them.  By serial number one is a 1946 the other is a 1948.  At first glance they look the same but on close inspection the transom clamps are different the fuel tanks are different the water tubes are different the tilt pin is different.  One has a twist grip the other does not.  I think OMC was getting rid of old parts.  The weedless lower unit and it’s ability to spin 180 degrees is only on the 1949 model.   They can be good runners but they can be temperamental too!   I will try to post a picture in another post.

Ed I don’t know about the ’49s but the earlier two I have, have a two impeller aluminum deal.  My motors could be a mix and match.  Meaning they were the same for so many years that parts might have gotten mixed up.  When they run they are quiet and smooth.  Very important to keep the fuel clean!   This picture shows the difference in the transom clamps and the twist grip.  One gas tank is tin the other is cast aluminum.

good luck with yours

Just a wood of caution relative to fuel system and ignition. These motors have a unique and rather complicated fuel/ carburetor system. The four cylinder ignition and associated spark plug wires and spark plug terminals are all neatly packed within the front shroud ALONG with that fuel system. Ensure that both fuel and high voltage systems are intact. NO leaks of either fuel or spark allowed under that shroud. Combustion outside of the cylinders is not a good thing.

These are fun motors.  If this is your first venture in the old outboard world just proceed slowly, seek advice when needed.

Keep us informed of your progress.

Everyone,

Edwin is my grandson, and age 14 I bought him a Jr. Membership. He’s really gotten the bug and has done a Mighty Mite that had a broken carb flange….It now runs great.. The 2 Zephyrs will certainly be a challenge for him, so any advice is well appreciated as those motors are way newer than what I tinker with. He has a Johnson 3 I picked up that we went through and he ran it for 8 miles!

This is what the club is about, —members helping member!

George that is really good to know!   Your grand son there has a challenge for sure!  Those carburetors on those Zephyrs are something crazy.  Be sure to heed JB warning about fires.  I will suggest to find some shorty spark plugs maybe J17LM champions or an equivalent.  Also some spark plug hoods for the plug wire ends.  The plugs and wires are to close to the front cover.   Don’t want no sparks in that area!

thanks for doing what you do!

Here’s a Twin-Z seen at Tomahawk 2024.  Rumor has it there was another one in Connecticut back in the 80’s.

Fun Motors.  Looking forward to seeing yours run Edwin…..
