Volvo penta 5.0 gi with a dp-sm outdrive. I've been working on this inherited nightmare for over a year. Getting ready to splash in a week or two and I'm in the process of puting the props on. Manual says to put the boat in gear so the props won't spin when tightening the nuts. Is this with the shift cable attached? Or disconnect the shift cable and do it manuallly. It shifts fine manually but when I try to move the control lever it won't budge. I can press the button and the throttle will move. Is there a safety features that will not let me put the motor in gear without it running or is there a problem with the cable or linkage. I should note I disconnected the cable to remove the outdrive but have not touched the cables at the control. Also, the boat has been sitting for 12 years. Any help is appreciated. Thanks in advance.
