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.

  • 1982 Mercury 115 6 cyl. spark plugs

    It is very, very hard to cold start. Nearly impossible without ether.

    I checked the plugs and they are these odd non post champion L76V plugs.

    What are the rec. plugs? Both the NGK and Champion web sites seem to rec. a standard type plug. Which plug and at what gap is recomended.

    I just bought this boat (my first) and am trying to sort through the problems. It seems to have a newer battery. An optima with 750 cca. I am going to have it tested tomorrow.

    I did order a manual but it isn't here yet.

    Hi,

    The Champ L76V is the std plug or a NGK BUHW . Either will be just fine.
    Check the choke system you have to hold the choke on to make it work. Are you using the fast idle lever on the remote control?
    This is free internet advice.

    Have Fun,
    corm

      where would the fast idle lever be? Where is the remote control?

        Okay so a quick search shows that for my single armed throttle, I put it in neutral and have the throttle opened?

        It has a key choke also. I push it in a few times before starting?

          As the previous poster said, the choke only works when you push the key in (or hold down the separate choke button on older models).

          So, the starting drill would be, pump the primer bulb 'til it's hard. Raise the fast idle lever. With the control lever in Neutral, crank the engine over while activating the choke. With a cold motor, keep the choke on until the engine fires.

          Once she starts up, release the choke and if the engine falters, turn the choke back on for a few seconds. Repeat until she runs smoothly without wanting more choke.

          If I recall on your motor, it doesn't have choke flappers on the carbs but rather a priming system which squirts raw fuel directly into the engine for fast starts. But it still works in a similar manner as a "choke", you have to hold the key in or push the button.

          If this doesn't help the starting drill, you may need to check whether you're getting power to your priming valve solenoid and that it's actually passing fuel when activated.

          p.s. if you value your motor, don't use starting fluid on it. Most starting fluids contain no oil, so you're really putting a strain on your bearings, pistons, and cylinder walls when you use it. If I recall, there is a type of starting fluid used with diesels which has a shot of oil in it. I assume this would be relatively safe to use, but you certainly need to be careful with this highly explosive stuff in a marine environment!
