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.

  • Bonding Wires?? 1987 OMC King Cobra

    I recently refinished my '87 OMC Cobra outdrive and replaced anodes. When reassembled I could not get continuity from the outdrive to negative on battery.

    I get continuity from prop to the bracket inside the boat on the transom, but I see no wire between this bracket and the block.

    Should I have continuity from prop to neg on battery?

    Um,

    You should. But you're running in fresh water in Mi right?. Are you trailered? I don't think it would be a problem (you said King Cobra .......It's a 460?)

    I seem to remember bonding wires from the drive to the gimbal and to the transom mount etc..... You should also have bonding wires from the transom plate to the engine block.

    Remember that your drive yoke goes into a (no longer available btw) rubber (read-insulated) coupler bolted to the flywheel/crankshaft.



    Regards,


    Rick

      Thanks Rick - yes, king cobra 460 (7.5L). I am not trailered, and I am in Lake Erie = freshwater.

      I checked again and found 1.6ohms from battery negative to transome mount.

      Not as low as I would like it. I was considering adding a bonding wire from transome bracket to engine block.
