Could use some help identifying old motors

Found a guy selling 5 antique outboards yesterday, $20 dollars a piece. The catch was that you had to take them all. It's the plain truth, but did warrant an eyebrow raised from my wife.

I could use some help identifying these, especially this one that I can't find any markings on.



I've been able to find out a bit more about the others.
Evinrude Mate 1.5hp, 1969. Looks like it's never been used. I'm most excited for this one.
1960 Johnson CD-17 5.5hp. Looks to be locked up pretty tight
Goodyear Sea-Bee model 025-3554 (could be 025-3564) and I'm not sure where to find resources/possible diagrams on this one. Per seller, ran but leaked fuel from the carburetor.
5hp Firestone I believe to be a 1958-ish based on the stock number. I believe the seller said he ran it at one point. Have the cowling, but it doesn't like to stay on.



That's about it - I'd like to try and get them running if possible, but won't hold my breath. I think of this as more of a learning opportunity without much lost if it goes horribly wrong. I have two buddies that could use an outboard <5 hp so if they run, they would go to a good home. Last choice is I may pretty one up and hang it on the wall or part non-working ones out to antique outboard enthusiasts.

Anything else I need to know? Can they all use modern lower unit oil? I'm assuming most of these need a 20-1 oil to gas ratio (or at least won't be hurt by running it oil-heavy for trying things out, right?).

Also please tell me if I'm in over my head and need to donate these to a museum or at least a more knowledgeable antique ob enthusiast.

Thanks!

Think I found the Goodyear Sea Bee, it's either a 49 or 50 5hp. Must be the 025-3564 rather than 3554. Not finding any results for the latter.

I am thinking several of them run 16:1 mix.

Do I get credit for the 5 1/2 JOhnson and the 1 1/2 Evinrude

Pappy, I think you're right. I found some writing for F-109 and R E Phelon on the flywheel. Best I can tell is that makes it a Neptune.

I appreciate the advice, I've already been tripped up by the 1.5's single lower unit oil drain.

AOMCI has been a great resource, I would like to attend one of the meets for the chapter in NW Missouri. They seem reasonably active.

I have a 1929 Johnson that is very similar to the first one, but Johnson Outboard Motors is cast into the fly wheel. It could a knock off of Johnson like Elgin or one of the other early engines in the 1930s.
