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.

  • Shift problems 82' Mercruiser 120 alpha 1 gen 1

    1st, Problem is when I shift into forward or reverse it doesn't fully engage until I give a little gas. I've adjusted the shift cables following a video on you tube which was very helpful. I've the process several times and still the same results. I don't have any play in the cables so those are good. To me it seems like I need the shift cable to extend a littlet more to fully engage the gears but I'm not 100% sure that's the problem.
    2nd problem is my boat runs fine for the first hour or so but when it's been running for awhile and I come to a stop, boat still running and I go to put it in gear it'll die like the neutral cut off is being activated. Not sure what's going on with that.
    3rd problem how the hell do I properly adjust the manual choke on the Rochester 2 jet. I get it close then the weather changes and the stupid thing will have a hard time starting. Drives me crazy.

    welcome aboard

    replace your shift cable (both first and second issues point to a worn out shift cable)

    regarding starting - 3rd issue: please describe your sequence you use to start the motor

    the proper sequence with a carbureted motor is as follows:

    with a cold motor
    two full pumps of the throttle
    press throttle only switch and move throttle to 1/4
    turn key
    when motor starts, back off RPM to 1500 for about 30 seconds
    pull back to neutral to re-engage gear selection

      Sounds about right with the shift cable, big pain in the butt. Now as far as starting goes, for the most part that's how I start my boat but sometimes it gives me ****. According to mikes carbs on how to adjust the choke is when motor is cold turn the butterfly closed then slightly more and that's it. Sound about right?

        yes. however if your fuel system has crud in it, the internal passages will plug up. in that case you may have to clean your 36 year old carb

        first make sure that your accelerator pump is squirting when you give it gas
        then make sure the choke is free and closes

            Check that the shift cable from the control box is traveling a full 3" from forward to reverse.
