The aluminum model "K" was only produced in 1922 as an answer to the aluminum Elto. They used the same patterns as the cast iron model and so although lighter, it wasn’t as sturdy. So many aluminum parts broke that it was an embarrassment and quickly dropped from the line. It isn’t even included in later Evinrude model lists. So you have a very rare bird for which parts are impossible to find. . . 🙄
