The only #'s on this motor I can find are, on the front there is a Sears tag that reads Model #60920 116824B. Under the starter is #701216. I took the top off and under the top was #900-0409-00. Can anybody please help me indentify the make and year of this motor? It is supposed to be a 3.5hp, liquid cooled(was told by marina), The cover is white plastic with SEARS molded into it. The instruments; On top is the throttle control. In the middle is two red knobs, one is low one is high speed, lean/rich adjustments. On the bottom is the choke lever. It is a single cylinder. Recoil starter. Is white in color. Any help is greatly appreciated!
