Neptune Outboard Motor

[Terry Beasley]

I've got a small Neptune model 1A that I have had for years. I runs well. I would appreciate any information on this motor. Thanks.

[John Drabik]

Refresh my memory. Isnt the 1-A Neptune also the Mighty Mite model?
Or was that the WC-1?

[Houston]

I have two neptunes, both of which I restored, but i cant remember the model #s. If you could post a picture I might be able to help you out. I am guessing single cylinder?

[John Drabik]

I dont have a photo of mine but I believe it was a WC-1. Its not nearby to look at to verify.
Single cylinder engine, weighs about 20 lbs. I think Muncie gear bought out Neptune or vice versa. At some point the WC-1 were made in different states by different contractors. The last Mighty Mites (WC-1)? were made in East Lyme Ct. by an outfit called Hudson Bearing from about the mid seventies to mid eighties. A Korean firm bought up the Mity Mites parts and production and promptly bellied up.
Didnt really answer your question and sorry for the rambling.

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

Anyone know the proper fuel/oil mixture for the Neptune WC-1? and perhaps it manufacture date?

Thanks..........

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. 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 use my chainsaw/weedwacker mix for the little use my outboards get. Some folks prefer non-detergent crankase oil at the engine builders mix. And still others prefer two cycle outboard oils. 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.

I run 16:1 two cycle outboard engine oil in mine, these are 30s era with cast iron heads. It blows a little blue smoke, but these old motors are smokey anyway. It should list the ratio on the name plate on the flywheel.

The Oil Gas Mix For the WC1 is 1/2 pint of Mobil Outboard oil to a gallon of gas. That is what is on the Brass plate of my WC1. What is the Muncie Neptune WC1 HP and What should you be able to sell it for?

I have a Neptune outboard model # 1a 39. I need the following items for a rebuild I am planning. Points, Condenser, Magneto, Rings, Carb Kit and gasket set. Does anyone have any ideas as to where I can get these parts?

[John Drabik]

I found some a condensors and points at my local auto parts store for some of my older outboards. It helps if you buy coffee for the counterfolk and they may make a serious effort to help you. Ive had good luck matching parts to pictures in old catalogues buried under the counter.

I have a Model A2 Neptune Outboard motor (3.3HP), serial #D6290A. I am looking for piston rings, part #2-11A and a gasoline tank valve, part #3-19A. The rings I have are broken and the valve will not close. Does anyone have a source for these? John from Michigan

[Jerry Lancaster]

Terry, your carb should have a # on the side, Check your Carb. number and go to this site and look up the number and that should give you the year. www.asecc.com/data/tillotson.html I got this site here on this forum a couple of nights ago to check our a Neptune Twin I just purchased. Hope this helps. Jerry

[Bill Geyer]

JANDB,
These folks might be able to help with the rings.

It may take some digging but this club has helped me allot.

You might take a picture of the shut off valve and Email it with an inquiry to various vendors. If you click on "Sponsors" at the heading of this page you might find some one who deals in carburetors/fuel tank who might have such a fitting.

Your motor is a Neptune "Junior" 4hp made in 1937.
Thats all I know about your motor, but you can get
more info at
http://www.aomci.org/index.htm
Go to the "Ask a member" forum. There's a lot of
help to be had there.
I have a 1951 Neptune m/A1, 1.7hp that came from
a garage sale. It started a collection that is up to
15 motors and growing.

Good Luck with your motor!
