Very old Johnson outboard

[David Jenkins]

Two questions.  First, I picked up a small Johnson outboard.  No model number on the flywheel.  As a clue, the rope socket is held on by four bolts.  The motor is covered in a lot of crust. Does anybody know where I need to look for a model/serial number?  I have looked at the transom mount, and underneath the powerhead, but can’t find any stamp. I’m new at this, so don’t worry about offending me with the obvious.

Thanks!

I can’t think of a small early Johnson having 4 screws on
the rope sheave. I would think that would be a good clue
for someone that is really knowledgeable in the early
Johnsons. Is it a square gas tank motor? How many
cylinders? Is it painted a color or is it silver?

Don’t the J-70 and F-70 (maybe the 300) have that goofy domed rope plate cover with four screws?

Tore it down and found the plate on the power head under the flywheel.  It’s a 1934 F70.

Thanks!

There’s an F70 on ebay right now with decent pictures in case anyone wants to see what an F70 looks like.

Is an F70  a little rare?  That’s a nuts price on Ebay!
