HI I have a 40 hp Johnson . A the start of the year the oil seal on the propeller shaft was leaking so I took it apart drained the oil and fixed . I pulled the shaft out and put it back in etc. but now I have no reverse ? . There was a wire in there that hook into one part . It had came on hooked I put it back were it was hooked . but still have no reverse . I am not sure what the part is called . New to boating and this site . I do not have a manual for it . The model number is 40es70 a . It is a Electramatic anyone know what i can do to get the reverse working again ? Thanks .
