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 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.

  • 1963 40hp Gale wiring

    Can someone tell me where a couple of wires go on the ignition switch end of this motor? Have original wiring harness, but no ignition switch. Wires in question are the two black ones that go under the flywheel, and the white one that goes to what appears to be a high throttle sensor. Model # of motor is 40DE17B.

    If I am not mistaken, your motor was made by OMC and is essentially the same as the OMC 40hp motors of that year. You might want to put a post in the Johnson/Evinrude section because there are some very knowledgable folks there.
    Please don't PM me on advice issues - let's keep that in the forums, so that everyone can benefit. Please note that I do not email PDFs, etc. I have a bandwidth limited aircard for internet access. My avatar does not mean I have any offical link to iboats. I just like it!

      At the key switch: The two black wires are the stop wires. They go to the two "M" terminals on the switch. The white wire is the start wire. It goes to the "S" terminal on the switch.

      At the motor: One black wire goes to the magneto. The other black wire goes to the center nut on the vacuum cut-out switch. Another black wire from the same nut goes to the magneto. The white wire goes to the corner of the vacuum cut-out switch. A second white wire from the same corner goes to the safety switch operated by the rotation of the magneto armature plate as you work the throttle.

      Of course, all these wires go through the junction box on their journey.

          OK, Heres one for you guys! Replaced the impeller and when I went to re-install gearcase I looked up in the motor with a flashlight to see how big a target I had to get the splined shaft back into. I could see some loose pieces laying across the hole. With a pick-up tool, I manged to pull them out. They were a rubber quad shaped o-ring about an inch id, A stainless spring, a metal retainer for the large end of the spring and parts of what seems like a ceramic washer that fits over the o-ring. Any idea what all this is and how hard it's going to be to replace?

            Absolutely!! That is the lower main bearing seal, fell off the crankshaft. The powerhead MUST be removed and those parts replaced/reinstalled as required. No options here, you gotta do it. If you don't, water will get up into the bearing and destroy it and the crankshaft---if it hasn't already.

              Thanks again! Kind of what I thought. Guess we'll tear it down and see what we got.
