it is a1969
the fuel ratio for a 1977 Johnson 6hp is 50:1. The mix can be moved to 60:1 if you will be doing a lot of trolling.
Model number 6303, would be a 1973 year model, 6hp Evinrude outboard.
Do not know exact wt but approximately 50 lbs.
The sticker on the side of my 6hp two stroke Suzuki OB reads 100 to 1. Unsure of the year.

The '88 6HP I have has had a 50:1 mix since it was new and still works fine. Just use a good quality oil.
The correct plug gap for the 1971 model, 6hp Johnson outboard, is .030-.035 in. It requires a Champion J6J, or NGK B6S.
although the sticker on it says 100:1, mix a 50:1 ratio. In 1986 & 1987, for some reason Johnson went to a 100:1 recommendation. I actually like a 64:1 ratio in my pre mix 2 stroke outboards. That's 2oz of oil per gallon of gas.
