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 else’s 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 it’s posted at the end of someone else’s 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.

  • Need help with Johnson Mile Master fuel tank

    I'm getting ready to go on a trip in a few weeks, and the last time I took the 14' Alumacraft out with my 5.5HP Johnson CD-11 1954 Outboard, I noticed that the top gasket on the Mile Master fuel tank (the gasket that the top handle and pressure pump and filler cap is in) was leaking.So, I proceeded to remove the screws and pull off the top tank handle/pump assembly.I carefully removed the cork gasket, in case I wanted to make a new one from it, (likely will use RTV) and noticed another gasket and thought I'd inspect it's condition.BIG MISTAKE. I undid the screws like an idiot, and out came two springs, a valve seat disc of some sort, and an aluminum washer, as well as a plastic & rubber plunger.Can anyone help me reassemble these things?If not, can anyone give me tips on a replacement fuel tank to use with this motor?Also, does anyone know of replacement tank pressure pump gasket/diaphragm parts? Mine's cracked and might not last another season.I'd be grateful!

    Welcome to iboats.Boy, are you in Deep Caca! No replacement tanks still in production. But don't despair. Don't know if Bombardier is still making replacement parts, but if you can find a dealer that's been around for awhile, parts were available until the OMC bankruptcy. The cork gasket and diaphragm were readily available. There are diaphragms with and without holes in them for the primer. The ones without were the same as the ones with, but without. A leather punch easily solves that. I checked a parts book I have with no luck, but a dealer with the old MicroFiche can definately help.Best of Luck! It'd be a shame to retire that fine Classic for a few lousy gas tank parts. I'll bet there'll be a few afficianados that'll be glad to fill in the gaps. Thanks for posting.
    Hey, Have you seen? They make Really Cool life preservers nowadays.
    So "Looking Dorky" is no longer an excuse for not wearing one.
