Yes, the '57 and '58 Johnson color schemes are also my favorites. You have a collection of great motors. Also like your recovery system - think of all the unburned fuel/oil that ended up in our lakes and rivers over the years.
I'm sure my neighbor did use the recommended SAE 30 oil but he must have used a mix ratio of like 10:1 or something - you wouldn't believe the smoke he generated. I can remember one Saturday morning he had it running and his entire boat totally disappeared in a cloud of smoke. His 2-cycle lawn mower did the same. I remember him telling us one time that he liked that smoke because he knew his motor wouldn't burn up!
