Please I need help, I have a Johnson outboard mtr, 5.5 hp, Mod #is either a CD-20R, or a GD-20R, Ser #2369055. I would like to know what yr, and what the oil mix for this engine is
kustommerc- I just looked up those #'s and wasn't able to be certain but I thought it was a 1963. But the serial # was correct? Could be a diffent HP? Here look for yourself.<br /> http://www.kencook.com/kccwww/marinepubs/marinepubs.html
