Help identifying the year of 2 outboards please

[AZcamperguy]

The first is a Johnson 10 hp.
Serial - E4383185
Model - 10R76R

The second is a Chrysler 20 hp electric start.
Serial - 1061
Model - 2021

I am trying to determine the fuel oil mix on them as well. For testing that they worked I did a 50:1 ratio. Does this sound right to you guys for these two motors? Please, let me know if more info is needed.

Here's the chart for Johnson 10 HP series:

I don't see your model listed.

Thanks for the link. I found 10R76 under the 9.9 models. The cowling has been repainted on mine so it may actually not be a Johnson 10 after all. If this is correct then it is a 1976 model. However, the last digit "R" is not listed but is on the plate?

Also, I found this page for the Chrysler motors but I don't see mine listed unless I am missing it?

I think I found the answer here

looks like 50:1 like I thought. I am posting in case anyone else runs across this question
Still think it is strange that my model number isn't listed for the Chrysler and isn't exact on the Johnson.
