i recently acquired an outboard motor with all decals and paint gone from the covers. the top cover has old evinrude emblems on the sides and a "westwin" emblem on the back. the control knobs look like the kind that were common on cars of the late 50's and early 60's. the i.d. tag has the serial number 18302E-E11130 and under that it says evinrude milwaukee, wisconsin, usa. it is a small engine, if i was guessing 15 hp or so. any ideas on what i have as well as any way to get shop manual type info on this rig ?<br />thanks,<br />C R A I G
