1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • 1972 Johnson 65

    I have a 1972 65 HP Johnson Hydro Electric OB. I got this motor for free with a boat and it started a few years ago once before I removed it from the boat and stored it for 2 years. I have re-mounted the motor and now I cant get ti to do anything....no noise..no nothing when I turned the key. I have the manual and it appears that the forward/neutral/reverse switch (in the controller) is broken.

    Is there a way to bypass the switch so I can start the engine? I just want to make sure that it fires up before spending any money it.

    Thanks.

    ps...anybody know of any cheap places for parts?

    There is a 20 amp fuse that comes off one side of the starter solenoid that provides power to the switch. That could cause your problem. But to answer your question you can run a jumper cable from the + side of the battery directly to the starter. Of course turn the key on to start it.

      if that doesn't work. un plug it, and jump the starter, this take the control out of the system. you will have to choke it to stop it.

        Thanks for the replies.
        I bypassed the starter solenoid and the started spun. I didn't want to run the engine yet..I still have plugs, lower unit gear oil and impeller to change before I fire it up.

        I have been searching...and someone wired in a 3-way switch and just manually flipped the switch when they changed gears. I may try this as a temp fix until I can get the part.

        Gonna have to study the wiring diagrams tonight to see how to wire it.

          there are several controls on ebay that will work with your motor. you want the hydro electric controler. take the prop off when testing, as it starts in forward, don't want any cut legs.

            Re: 1972 Johnson 65

            I've been reading tons of posts about the switch going etc. Most say to START the engine and try X, Y or Z. I can't start the engine. I am assuming that the switch being broken (and possibly set to reverse at the time it physically broke) that the neutral safety shutoff would be engaged (starting circuit open). Is this a safe assumption? Or should I be looking at a different reason for it not doing anything when I turn the key?

            I just don't want to be chasing something that is not the cause of the problem.

            Thanks again for the responses.

              Re: 1972 Johnson 65

              Update:

              I found 2 things that were preventing it from starting -

              1. Safety switch (on motor next to throttle linkage) was not fully engaged.

              2. Shift switch (in control) needed "broken piece" to be pushed in to make contact (power from purple wire to green wire).

              I am going to make a manual switch to control forward/neutral/reverse (3 way off/one on/both on) and hook up the green and blue wires to that. From what I read Both on = reverse, one on one off = neutral and both off = forward.

              Thanks for the suggestions again. I hope this thread helps someone else with the same problem.

              Once I have the plugs changed and the lower gear oil changed I am going to fire her up...I am sure I will be back with more questions then. (this is my first OB so it is all new to me).
