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 threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

2. Old threads should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • gimbal bearing replacement

    K- should be a simple one for most of you out there.
    merc. 165 gimbal bearing. In regards to lube and installation, the new bearing has a hole on the outer perimeter...which direction should this be placed when installing? Also in regards to lubrication...it would make sense to rub some lube around the bearing for ease of installation, but what about overall lubrication? Firstly, should I clean out the existing lube that was sitting behind the old bearing? Secondly, the gimbal housing has a tip for a lube gun, is this what lubes the bearing housing?...anything else I should know?..
    Oh, one last thing....another post-er mentioned that the retaining ring doesnt need to be reinstalled. Is this true, and if so, why was it there to begin with? (as it was a pain in the a** to remove)

    Re: gimbal bearing replacement

    retaining ring was used on the very early unit that didnt have the grease fitting. You dont list a year or serial number but it will accept the newer style gimbal bearing. If you do have the fitting on the side of the transom ,line up the hole with the grease fitting hole, usually around 5:00 and install untill fully seated
    NO PERSONAL QUESTIONS, THIS IS WHAT THE FORUM IS FOR.

      Re: gimbal bearing replacement

      which direction should this be placed when installing?
      absolutely in line with the hole in the carrier.
      Also in regards to lubrication...it would make sense to rub some lube around the bearing for ease of installation, but what about overall lubrication?
      ya wanna lub the brgs. inbetween the inner and outer race. this is done via the grease zerk found on your gimble housing.
      Firstly, should I clean out the existing lube that was sitting behind the old bearing?
      seems like a good idea. it isn't doing anything. it's just excess lub from over lubing.
      Secondly, the gimbal housing has a tip for a lube gun, is this what lubes the bearing housing?...
      this lubs the brgs. inbetween the inner and outer brg. races.
      anything else I should know?..
      according to mercruiser, ya wanna replace the brg + the carrier. they are a mated pair from the oem. ya wanna read mercruiser service bullitein 85-26 http://www.boatfix.com/merc/Bullet/85/85_26.pdf

      lastly, i've read that the snap ring isn't necessary. i put mine back though. ya can make some big snap ring pliers with some long needle nose pliers that i got for cheap at harbor freight.
