I just installed new shift/throttle cables on my 93 Evinrude 2cycle 90 hp motor. I think I have them adjusted close to where they need to be.....however....it seems when I shift the control from neutral to forward and then to reverse it hangs up and doesn't want to completely shift unless I walk to the motor and just slightly touch the prop with my toe. Then when I go back to the control handle it finishes shifting into gear. Is this the way it should be if shifting without the motor running.
