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.

  • Impeller change in 25 hp Mercury

    New to board and boating. Thanks in advance. Have a 1993 25 Merc eletric start and am changing impeller. Four lower unit bolts disconnected. Where do I disconnect the gear linkage shifter in order to drop the lower unit? Is there a nut to loosen or bolt to take out or what? Should the motor be in gear or neutral while doing this? Any other tips? Thanks much.

      Thanks very much. We lived in NLR for 15 years and spent some time in HS Village and Lake Ouachita. Beautiful country for sure. My neighbor is a FedEx electrician and he is giving me a hand with the impeller change. If we can't figure it out, I may well contact you again. Our primary question is how to disconnect the gear linkage shifter. There is a 1 inch rubber boot on the side of the motor next to the linkage. When we take that out we can see a square bolt inside. Do you know if by loosening that bolt, the linkage is disconnected? Thanks again.

        This 25 merc is an easy fix with a manual. If you don't have one, get one and it will guide you through step by step. Good luck.CU

          You will need to disconnect the battery and remove the starter then you will see a little black or sometimes blue cleviis pin at the top of the shift shaft.That pin unsnaps from around the bulbous portion of that clevis and just pulls out.Carefull now as there is a washer in the mix to operate the reverse lock.The soap opera continues.

              What Hondon said!! ! !! I didn't keep up with mine washer and my throttle and linkage got all out of adjustment. Cost me a few coins to get it all back in workin order.
