Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

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

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

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

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

    Are you sure you bought a swtich with choke?? many swtiches dont have it.

    two black wires? no stripes? well some boats have two ground wires, one comes from the battery (-) and the other one is the boat ground, usually one is for accesories and the other one for the kill switch.

    my two cents

      Re: Yamaha Key switch wiring

      Can I hook the blue wire (choke) to any other color wire on my new switch?
      Is it possible to hook the blue wire (choke) to yellow wire (Key On power)
      will that work for my choke?
      Will the motor run if I don't hook the blue wire up?

      Thanks

        If the switch doesn't have the push-to-choke feature you cannot activate the choke on the engine. You cannot hook it to any other position. You will have trouble starting the engine because the choke is needed for cold starts. The engine will run without it but will be difficult to start when cold.

            Re: Yamaha Key switch wiring

            Any aftermarket starter switch will work at longest as it has the "push to choke" feature. When you go to the store ask for it that way or if you are buying on line make sure it is specified as "push to choke"

            Dont you have a manual choke in the motor?, if so you can use the switch you have without the "push to choke" feature, just DO NOT connect the blue wire anywhere, you will need to use the manual choke to start the motor.

              My old key switch had a push in choke I think. Everytime I push it in I dont hear any clicking sound. I just turn the key and it fire up. I dont think there any manul choke on my engine. If there is do you know where it at? How do you manully choke the engine.

              I believe it a 1996 or 1997 or mid 90's
              90HP yamaha o/b

              Thanks
