Hello

My first post on this forum.

I'm in the process of doing some restoration work on a 1952 Evinrude 3hp Lightwin. This one is model # 3012-05355 and was purchased new by my great uncle when he retired. The motor has really seen very little use over the years and is in really good condition. There are a few small scratches in the paint and the decals are a little discolored after 56 years but for the most part this little guy is a cream puff. My great uncle passed away in 1968 and I have had the motor ever since. It hasn't been in the water for the last 40 years.

Back in the 50's I got my time in running this motor on several day fishing trips with my great uncle and my dad. Lots of fun for a young kid. One week long fishing trip to Cheboygan, Michigan in October 1955 was the crown jewel of them all, I got out of school for a whole week. :)

Anyway back to the motor. I decided since the paint was in such good shape I wouldn't bother redoing it and the decals. I have so far replaced the points, condensers and the badly cracked ignition coils and sparkplug wires. I also rebuilt the carburetor with a new float and float valve and gaskets.
I didn't open the engine up beyond removing the exhaust chamber cover and the cylinder head. There were some carbon deposits but not too bad.

On the bottom end I changed the gear oil which looked brand new and replaced the pump impeller. The original impeller was in good shape but a little stiff compared to the new one.

The only major repair work involved the swivel bearings/pads that are part of the steering pivot. The original pads were canvas faced rubber and the top one had delaminated and was pretty much trashed. Unable to find any material like the original I ended up cutting pieces from a section of plastic downspout drain tile. So far it looks like it going to work.

The only part so far that I'm still thinking about replacing is the rubber clutch collar in the prop. The original is still intact but hard and showing some cracks. So far I haven't been able to find a replacement. Maybe someone knows where to get one?

I'll post some pictures when I get this little guy ready to run. And then I'll need a boat to try it out. ;)

Great story. I have a 3012 also on my list of engines to work on but mine has seen better days. Please post pics when you can.

Personally I would not replace the prop until you had a problem with it.

Oh, and welcome to iboats! :)

Thanks for the reply Steve. I'm thinking along the same lines for the prop too. If the rubber is too hard to act as a clutch the shear pin will probably pop and protect the drive system. I think it will be Ok as long as I don't mess with it.

Re: 1952 Lightwin Restoration

After all that work, why on earth would you not replace the rubber? It is there to protect the drive train. You are supposed to be using a stainless steel drive pin, not intended to shear unless really abused. The closest parts book I have is 1955 but as far as I know the rubber is the same. Part number is 300565 which is superceded by 315471. The drive pins are #203230. Both are available from an Evinrude dealer or several on-line sources. Just do it.

If I can find a replacement bushing I'll pick one up. I didn't know if the bushing was still available as a replacement part. Thanks for the all important part number. I have a small bag of original drive pins and cotter pins.

Edit: My parts list shows the same original part number, 300565. The cross reference number was what I was missing.

Re: 1952 Lightwin Restoration

Welcome, Ron! That?s a great story and I?m glad that you are preserving the little Yachtwin. I have been in love with those cute little 3?s for a long time.

Back in 1973 while at my father?s associate?s cottage in Lake Of Bays, he showed us his new ?cheap little motor? purchase. It was a flawless 1953 Johnson 3 that had been in use at a local lodge (that seems like a contradiction, in use at a lodge and flawless). Meanwhile my dad had a 1967 Johnson 3 horse folding weedless that he bought to replace his worn-out 1950 5 horse. 1967 was the last year for the metal cowl and was the same as a 1957, the year they added the carrying handle on the front. Evinrude I believe had a carrying handle on the front since at least 1954 if not the very start in ?52. My reference stuff is buried in a crawl space and I?m not sure what is still around.

I have among other things a 1971 Evinrude 4 that really is a direct descendant of the 3. Mine has very low hours and is a straight drive rather than the weedless. I was shocked when BRP showed a decal set for a 1971 Lightwin 4 available as NOS (New Old Stock) at a dealer, so I contacted the dealer and have the last 2 NOS sets being shipped to me. Score!

Thanks for the welcome Cam. Like you I get a kick out of these little motors or as my great uncle called it a KICKER.

Here is a picture of the progress during reassembly.

For more pictures follow this link. The files named evinrudexx are lower resolution and for all the gory details the P numbered file are full resolution.

Mine has the handle as part of the cowling right under the mixture knobs.

Re: 1952 Lightwin Restoration

Hi Everyone,
I have a 1952 Evenrude Lightwin 3012.
I picked it up for $47.00 at a flea market
near my home in Avon, New York. Got the float cleaned out with gumout
works good with a 2oz to 1 1/2 gallon mixture - ran it at Butterfield Lake in Redwood near the 1000 islands this past summer - But what is the correct mixture of oil to gas?

Also:
I'm wondering

(1) what size to use for replacing the "Propeller nut cotter pin." I want to get a few for backup...

And,

(2) has anyone modified their 3012 by running a gas line to the carburetor
via a gas tank. I'd appreciate you advice.

Thank you,

Len

Sort of, but start a new thread! But a good subject line will catch others that will have an answer for you.
