Dating vintage neptune outboard motors

13 Jun

John ok the 1A model was made from 1938 to to about 1960 was very common and such a great lil put put outboard then when the 1970's came around they changed the 1A model to the WC1 and its about 1.7 hp at 4000 rpm i can look up the model of the carbutetor and tell you the year and what size outboard it is Not sure if this answers your question specifically.

However read the label on the oil can and use the oil manufacturers recommended 2-cycle mix ratio for that specific oil.

I use my chainsaw/weedwacker mix for the little use my outboards get.

Some folks prefer non-detergent crankase oil at the engine builders mix. The main difference between all is the lubes performance ( clean burnability at engine temps) which vary considerably between two cyclemarine (water cooled)and chainsaw(aircooled) engines.

That way your covered for lube specifics regardless of whatevers written on the engine.

Especially when mixing for older engines with the modern two oils which most likely have better lube and burning qualities than old stock oils.

I dont have a photo of mine but I believe it was a WC-1. At some point the WC-1 were made in different states by different contractors. A Korean firm bought up the Mity Mites parts and production and promptly bellied up.

If any can help, i just purchased a older evinrude outboard. I don't know the year but the Model # /Model# 3886M -02590 Also is there any place to get a replacement cowling for this motor?

I would like to get it running but first i have to know year,hp,and a place to get parts.
