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.

  • adjusting lower shift cable - Alpha I

    I'm trying to adjust the lower shift cable on an alpha I drive (motor is mercruiser 4.3 L V6). The instructions say to manually shift (push in on lower shift cable) the drive into gear while some one spins the prop. I've got that down - the drive shifts fine into gear. The instructions say to adjsut cable so that you measure exactly 6 inches from the center of the brass barrel to the cable end guide. Here's where I need clarification. Do I measure to the end/tip of the cable end guide or to the center of mounting hole.

      What year?
      If you actually have an Alpha I, then go up to the adults only sticky at the top of the forum, and download service manual #6. Section 2 has step by step instructions with drawings on how to adjust it.

      I would be very careful with mercstuf info. It's not always accurate.

        Re: adjusting lower shift cable - Alpha I

        Thanks for the replys. The drive is an Alpha I gen II (1998). I downloaded service manual 14 and instructions say exactly 6 inches from center of mounting hole (cable end guide) to center of adjustable brass barrel. The instructions I had were a little vague in this measurement.

        Hoot, I also printed out your instructions and will keep that for reference. Thanks again.
