    Cant shift into forward or reverse!-gctid389589

    I recently reinstalled my cobra out drive back on to my 1989 Bayliner 2150 w/ a 5.8L, and she started on the second try. When I went to put it into gear the prop started moving at a low RPM yet the throttle was very stiff and would not fully engage. I didn't want to force it so I didn't push my luck and just shut her down. After checking the newly filled gear case the oil was filled with tiny bubbles, does any one have any idea what I am up against? Could I have not aligned the shift rod end correctly when reinstalling the out drive?

    Please any help would be appreciated!

    Just curious what manual where you working out of ?

    To reply to your questions yes you could have installed the drive incorrectly, and the manual would have given specific instructions on how to properly fill the drive. IE: what holes on the drive to put the gear oil to.

    The good news you caught the drive problem, before you blew the gears.
    Be good, be happy, for tomorrow is promised to no man !

      I was using the original cobra outdrive and engine installation guide from cobra as if the parts were new.

          Did you remove the lower shift cable ?

          What gear did you have the shifter in when you reinstalled the drive ?

          There are three holes on a cobra the one on the top which is the dipstip

          one on the side near the middle

          one on the bottom which is the drain.

          Which one did you use to fill the oil and how did you do it, with a pump?

            I did not remove the shift cable.

            when I reinstalled the drive I had the throttle in neutral and the out drive was in the middle setting.

            filled from middle hole with dip stick rest in its hole but not screwed in.

              I believe on the shifter has to be in forward when you reinstall. Check these manuals and these 4 articles it may help

                The shift rod height should be 7.200 inch measured from the top of the rod v-block to the mating surface of the lower unit.

                It should be assembled in neutral but can be assembled in any gear position as long as the remote shifter is in the same position.

                Keep in mind as you probably already know, the lower unit cannot be removed from the upper without the entire leg being removed first.

                  No, h..l No. Shift in neutral, drive in neutral.

                  If it worked before, and you did not disturb the shift rod when the drive was off, then it should have gone back on in the neutral position and you should have no problem there.

                  Remove the upper and lower cables from the shift bracket on the engine. Then figure out which cable is hanging up - the upper or the lower. To shift the drive without the engine running, someone will have to spin the prop.

                  If the lower is the one that is stiff/binding, then the drive needs to come back off. If the lower shift cable is the original it needs to be replaced. With the drive off, you can verify the drag on the cable alone, OMC has a spec in the manual for this. Then verify the shift rod height in neutral, and make all the cable/belcrank adjustments in the manual. Once the cable is smooth (new or old), and adjustments are correct, it will work fine.

                    To ensure I am in the neutral position:

                    - The throttle should be pulled out and pushed forward right? The throttle wont stay out(neutral position) with out being engaged in the forward or reverse direction.

                    -The stern drive shift rod end should be in what position? lowest, middle or top point?

                      Shift/throttle control in neutral - straight up, no throttle, but it doesn't really matter on the throttle cable as long as the shift cable is in neutral.

                      Not sure what you mean by "The stern drive shift rod end should be in what position? lowest, middle or top point?". The shift lever arm on the starboard side bracket of the engine should be straight up and down. The manual has all the details. If you don't have the manual let me know.

                        The neutral position is the CENTER, which is the position it should be in when you verify the 7.200 height dimension previously mentioned.

                          Ok, so tomorrow after work I'm going to attempt this again and remover the drive. Just to make sure, as I only have one gasket set left, im going to keep the throttle in neutral and the v rod should be 7.200" from the top of the mating surface? Sorry if I am bothering you guys just wanna make sure? SEE PICTURE

                            The "mating surface" is the horizontal surface of the lower unit where it mates the the upper unit.
