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.

      Re: Johnson HD25 Rebuild kit

      Hi Ron, Your motor is over 50 years old - not likely to find a kit, per se. However, you may be able to get it going with some sleuthing, ingenuity, and good luck. I'd start in one of two places.. Here: www.aomci.org or Here: A long-established marina with a mechanic who's sporting gray hair and a name like Butch, Bob, or Duke. You want the guy who was there when the motor came out in the late 1940s. You also want the guy who hasn't become so cynical that he'd rather sell you a new motor over fixing up your old gem. He might just have a stash in some back shed with what you're looking for. What exactly does your motor need? A simple tear down, thorough cleaning and reassembly might be just the ticket...- Scott

          Re: Johnson HD25 Rebuild kit

          I rebuilt one of these motors a couple of years back. There really isn't much in the way of kit required for this motor. As long as the crank, pistons, rods, and bearings are in reasonable shape, all you should really need is a fresh set of rings and a head gasket and some sealer 2000. I placed an ad on the AOMCI board for these parts and had three responses. I ended up buying the rings from a Dan Gano out of Spirit lake Iowa. Check out his site at www.ganotech.com. The other things you should probably replace are the impeller, the condensors and the wires. The points can easily be sufficiently cleaned up without replacement. The carb is simple and will only need a good cleaning. There is a guy on ebay who is constantly selling impellers for these motors for about $10.00, I bought one from him. For the condensors and wires I got lucky, my local OMC (BMC) dealer had these available. I hope this helps.By the way does anyone out there have a lower cowl for this motor? It's the one part I need to complete the project.MG
