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.

  • noise in lower unit

    Lower unit has noise when boat is in gear. The faster you go the faster and louder the noise gets. It is a clank noise. If you turn the prop when motor is off and in neutral it will make the sound then. Took off lower unit and removed prop. The noise occures when you turn the shaft that the prop was on. Can anyone tell me what the noise can be. Sounds like a bearing, but I do not know which one it could be. Motor is a 1980 Chrysler Charger 115.

      Hi joker The only way to determine what the noise is to disassemble and look. I know you didn't want to hear that. What ever it is, it's not good. I would suggest you obtain a manual first.

        Alcan, We did tear down the lower unit with help of manual. You would not believe how easy it was to do with the manual only took an hour. The foward gear has three teeth knocked out of it and the pinon gear will most likely have to be replaced also. All happen from a very stupid mistake. Removed Pivot Screw in lower unit caused the shift yoke to fall and when engine was put in foward gear it put the gear in a bind causing the teeth to break off. Found a dealer in the area that can get parts without any trouble. Also the dealer helped make the manual. So we are very lucky to have someone so close and friendly to help us.
