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.

  • How to HOT WIRE 1978 70 HP Evinrude

    The boat was completely submerged in salt water. I have cleaned everything up as in the clymers manual. Replaced the key switch due to salt water corrosion as well as some other electricall connections. I was told I need to get this motor started to get the water out, time is of the essence. How do I start the motor without using the key switch, Are there a pair of wires I can jump? Please help.

    Unplug the big red plug on the main wire harness and then jump the starter straight from the battery and it should have fire. You will have to reconnect the red plug to cut theengine off, either that or choke it down till it dies.

      It seems when I have the spark plugs in, there is too much compression to turn over. With the plugs out the starter turns the flywheel fine. Just with the plugs in it is like one turn and jams up. Any ideas? Is it hosed?

        Dusle, Did you get the water out of the crank case? Need to lay the motor down to do this! Then take the plugs out and crank it.The water can only get out thru the ported holes in the piston!steve
