Evinrude introduced "Hooded Power"in 1935 with there Lightwin Imperial (an alternate firing twin) and Lightfour Imperial models. In 1936 front covers were added to the Sportwin and Fisherman models . . . 😀
i am going to see if i can get the junk guy to put it on hold for me.. but i can tell you it has a recoil on it and the heads are shapped to go with the cowel.. the power head is about the size of the TD20 though
