So I spent the week manually turning the motor and fogging the cylinders with Sea Foam - Deep Creep. Today I did my first compression testing. I like the numbers I'm seeing but I'm not an Evinrude expert. I managed to get an original 1973 Service manual for my engine - a 50373R - but I can't find compression number listed in it.
So I thought I would look for some opinions here. I did several tests but here are the results from the last three (where I actually remembered to clear the gauge each time).
Upper cylinder: 166, 164, 165
Lower cylinder: 157, 155, 158
I was a little surprised to see numbers that high, but again I wasn't certain what kind of compression numbers I should be looking for on this motor.
Anyone see a problem here?
