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.

  • Mercury 175xl Saltwater idleing

    Im not sure what the idle range is for this motor? Just bought the boat used and it idles at about 1100-1200 and that seems high to me. It also grinds the gears pretty hard when putting in gear but I think that is a result of the high idle. I'm not sure where to adjust the idle on the motor. Can anybody lead me in the right direction? Can't be that hard but there are a lot of things that are in sync and I don't want to adjust something out of sync. Thanks

    it should be below 1000, like 800. First check the throttle control cable and make sure it just pushes the throttle linkage tight against the stop before you do any link and sync stuff. It could just be a throttle cable adjustment is needed. There should also be a screw adjustment at or near that stop, though I'm not familiar with that specific motor.

      Make sure your tach is acruate. 800 is corect at idle. BUT when going into gear you have shift quickly don't ease it in.Make sure your tach is right.
