1981 40hp?

[pipewrench]

I have a 1981 40hp, moel E40RWLCIS, but all my searches show a 40hp was not made in 1981. Not sure what the "S" means on the end of model number, but the CI should make it a 1981 model. What am I missing here?
Also can someone here tell me how to get to the four bolts that tighten the swivel bracket? I have almost a 1/4" gap at the top of the swivel bracket and can see the threads on what appears to be quarter inch bolts. I cant see the bolt heads or any easy way to reach them. Please tell me there is an easy fix, without a major teardown. (fingers crossed)

Look close at model number to see if the "I" could be a "T" which would be a 1983.
Not sure which four bolts you are talking about.

Same problem here

I realize this thread is over a year old, but I m researching the same problem. My Evinrude work twin 40 is model number E40RWLCIS. Did you ever find out why this motor does not show up anywhere?
