  • 72 Johnson 65hp throttle inner cable too short

    I have a 72 65hp johnson that it seems like the inner throttle cable is to short. I adjusted the trunnion all the way out and it's still about 1/2 inch too short. I've checked the control box for sticking/rubbing and it's still good. I attached a pic for detail.

    the cable has 2 bends bigger that 90 degrees and a couple feet under the stern of the boat.

    any ideas?

    Does the motor run okay and does it idle properly ?? If it does, I'd try a new cable the correct length.

      Those type cables are still available and surprisingly not too expensive either. So either buy a replacement, or make sure all the bends and such are not keeping it from fitting. Make sure that the control handle(s) are in their proper position while the engine side is in that same position too. Could be one is slightly off a little. That would make all the difference. My OB uses something very similar. Are you sure you didn't swap the throttle cable with the shifter cable? Easy to do since the look alike. One other possibility is to find some wire the same diameter as the inner wire size and just replace that...

        Very common situation. The inner wire breaks at the clamping screws holding the cable end on. So some genius merely reattaches the cable end. That doesn't work----as you can see.

          There is only one cable on the 1972 model.----Shift is electric.

            Yes. With the cable off it runs great. I just took all the bends out of the cable from where it was routed. No luck. It's been like this since I bought the boot. Wondering if previous owner may have cut the inner cable shorter for some reason?? Its like the inner piano wire is just too short. I might try and replace the throttle cable, but just need to hope there is more exposed wire than what I have.

              That makes a lot of since. I think I'll just go ahead and give a new one a try. Saw one on iboats, I believe the pre 79 400.

                I think this is the correct one for my 72. Only one that has both wire ends.

                  Update.
                  Changed out the throttle cable with one from iboats. It's still too short, doesn't reach the throttle by 1/2inch with trunnion adjusted all the way out.

                  Any ideas? Maybe something in the throttle linkage on the outboard?

                  Thanks

                    Then that sounds like something is either broken or put together wrong in the control box.

                      Is the inner cable wire flush with both ends of the cable guides ??

                        Yes, both ends are flush.
