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.

  • how to fix flywheel magnets?

    I have a 1985 2.5 seadrive that two of the magnets inside of the flywheel came loose. It appears like the epoxy just gave way. i see there is a repair kit from outboardparts.com that has little hold down clamps that are attached to the flywheel. The problem is that right where i would have to drill and tap a hole to put these in is where there are drill holes i assume were for balancing the flywheel? Is there any reliable way to re-epoxy the magnets, or would it be best to start looking for a used one? Thanks Steve

      Duro 2 tube epoxy works as good as anything, clean flywheel until shiney, remove all epoxy from magnets. Apply even coat of epoxy to magnet, magnet will hold itself to the flywhell, until the epoxy sets. Remove excess epoxy. The magnets all have to be installed same direction. Let set 24 hours. If you remove all magnets to reglue I think the spacing in 7/16. The magnets not timed to flywheel.
      Help somebody every day, if you can.

        http://outboardparts.com/omc/mall/35rk.asp sells the magnet retainers that hold them into place and you don't have to use epoxy. They run about $48 for the kit and were featured in one of the boating magazines last month.

          I forgot to add in the previous post, that you can epoxy the retainer in place or fill one of the balance holes with epoxy, then drill and tap it for the retainer screw.If you decide to epoxy the magnets, use the factory epoxy packages (listed in the Parts and Accessory Catalog) and bead blast the magnet mounting area. If you don't, any corrosion will build up and pop the magnet(s) loose after a while. Epoxy kit, enough for 2 magnets #431929single magnet and epoxy kit #584304

            after i put in the retaining clips and fill in some of the balance holes, do i need to re-balance the flywheel? If so, can any shop do this?
