I cant remember just when I became aware of
of this model. Took several years of searching
before I found one. This video is about what I
have learned about them since then.

Appreciate the comment.
All the pictures, before and after, are of 2
motors that have found their way to me.

I acquired my SportTwin 10 years ago and parked it, never bothered to look for the model/serial plate.
What holds the lower unit in folded position? All I can determine is by tightening the bolt on the hinge.

Just the swing bolt holds it together. Be careful not
to let the bottom half just drop. That can damage
the connection on the impeller.
Could you look at yours and see if it is an N-1 or N-2 ?
Since getting the first motor I have saved a picture
of any remaining decals I have come across. I
have a pretty good understanding of the design and
fonts. However all the examples I have discovered
are in poor condition only revealing a tinny glimpse
as to the colors. I believe I know the colors for the
most part although not I’m sure of the exact shades.
I believe the background to be a grey but possibly
silver. None of the examples I have found would
indicate the background color was silver but there
condition isn’t good enough to rule that out.
I’m also not clear on the color of ” Evinrude” on
the side decal. If you could post what you have
or email them to me at old.days@yahoo.com I
would very much appreciate it. These are some
of the best examples I have discovered but even
the best ones are poor.

August 8, 2023 at 11:35 am #2789561N 219 just made its way to me. Tank is a bit smashed in, but other than that everything looks to be in great shape. I found it at an online auction out in Arkansas. A fellow AOMCI member was kind enough top pick it up for me and hold it until a racing buddy could pick it up and finish its travels to Indy……
I will get some photos and post of a great survivor.

Looking forward to seeing your pictures. If the tank is just a little smashed that’s
better than most I’ve seen. Does yours have a nut or screw holding the prop on?
Check the # on the carb. If its MS4B its the original.

August 17, 2023 at 11:37 am #279334Tubs, it is a nut on the flywheel and the carb is in fact the MS4B. The butterfly actuator arm floats very free, what was the mechanism to make it keep position. Do you have one you could send me a photo of?
Thanks
I will get photos of this one Saturday.

What you’re missing is the spring and pointed slug
that keeps it in position.
Your MS4B carb is probably unusable if you want
to run it. You’ll find that the metal has become
soft and brittle. Tighten anything threaded and the
threads strip. The carb was used on several later
motors and the issue with the pot metal was resolved
somewhat but caution should still be used when tightening
anything on the later ones as well. I believe any MS45
is the same but the MS45-A & MS45-B are the easiest to
find because it was used on so many Neptune’s BUT
you don’t want an early A as it will have the same issue.
The only difference will be the fitting for the fuel line.
The Neptune’s are plentiful and not in high demand.
Often you can buy the whole motor for less than someone
will ask for just the carb. If your carb is still in one piece
its nice to keep with the motor as many have turned to
dust. Its the prop nut that I’m curious about.
