Re: Elgin outboard
I believe that is a 571-58791, 59 7.5 special value motor. Built by West Bend which became Chrysler circa. 65.
Don't know if this will help."adjust shift rod coupling so gear shift control rod is in the horizontal position in neutral". (Gear shift rod is attached to the top of the vertical shift rod). Coupling is behind swivel bracket below the power head.
