That's another outboard all right! <br /><br />That's a 1969 5hp model you have there. Built by the Eska Company for Gamble Skogmo. Eska was in the buisiness of putting Tecumseh engines on top of their own outboard legs.<br /><br />I don't have much info on Eskas, but I'm sure there's someone here who does if you have any questions.
