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.

    Re: 1984 mercury 50 wiring

    it has 4 wires coming out of the ignition/ throttel lever box. the colors are brown, purple, light green and green. the brown wire is hanging loose by the tilt pump. i cant see where it goes. the tilt/trim just clicks when u use the switch but i can cross the solinoids and make it work. can anyone help me figure this out.

      Green or green/white is trim up, Blue or blue with white is trim down.they go from throttle button to relays usually mounted on power head.There should be more wires coming from the box than 4, The manual I am looking at looks like it has 6 plus the two for trim. which are seperate from the connector.

        Sorry. I had another look at your memo .. since the the wire is hanging loose at the pump, one can assume that the wire burnt off or got disconnected from the pump motor, both wires get reversed for up and reversed again for down. if you cross the solinoids, it may be getting the ground from the engine.

          Thanks for the help. The 4 wires i mentioned are not the only wires coming from the box. There is others but i know where they go. I think the brown wire that is hanging loose is the only reason the switch doesn't work. The wire still has the terminal ring on the end and it is not burnt or corroded. Nothing seems to be missing from the pump, so i dont know where it goes or if it is supposed to be hooked up.
