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.

  • evinrude 1957 7.5hp fleetwin

    Just found a fleetwin on the side of the road waiting to get picked up by the garbage man, but I beat them to it. Just what I need another project. Any advice on bringing this thing back from the dead would be great. It looks like everything is there including the pressurised gas tank and fittings. It also is a very clean motor inside and out. I'm a big dumby when it comes to these things so any info will be greatly appreciated.
    Thanks

    Hey, that's a good find! I love it when these things happen. I saved my 1946 Zephyr from the scrap man and my addiction just went from there.
    The first thing I would do, is take out the spark plugs and spray some WD-40 in the cylinders. Get it all loosened up. Once it's loosened up, take a compression test. You want the readings to be as close to the same as possible and with that motor, 75 - 80 psi or better is good. If you find good compression readings, then I would check over the ignition system. I'm willing to bet, that's why it was set by the curb. The coils probably are in need of replacement and no one wanted to put the money into it. Those old Fleetwins are good old motors, when tuned and running properly.
    Thirdly, check the oil in the lower unit. See if there has been any water intrusion and the oil looks like milk shake. These are a couple good starting points for you to work with and see if it's worth spending any money on it.

      Boy I hate when that happens.....and its not to me.....LOL. I usually have to PAY $20 at garage sales. Good advice above. I have 2 like yours. One was found to have a bad coil, which was an easy fix. The other had the water pump stuck, which made it seem like the powerhead was stuck.

        This might be a stupid question, but how do you check compression. The coils are cracked and the spark plugs were pretty worn out. Everything else seems to be in good shape. I will drain and replace the lower unit oil.

          I would beg, borrow or steal a compression guage.

          Yea, you'll want to replace the coils if they're cracked. If the compression feels good, then the "lack of spark" may be why you found it.

              Re: evinrude 1957 7.5hp fleetwin

              Ok, found a compression guage and I checked compression I had 50 psi in each cylinder. Is that good or bad? I also drained the lower unit oil and it was filled with water and sludge. I guess I'll have to get a gasket for the lower unit and also replace the o-rings on the fill and drain plugs. Does anyone know a good source for service manuals that won't break the bank. Or is there a web site that has a printable pdf? You guys have been very helpful but I could use some pictures. Man I have tons of questions. I hope I'm not a pain. Can anyone suggest a brand of coils to get or does it matter? I appreciate all of the help.

                50 lbs is low. But it will probably run if the rest is in good tune. You might want to pull the head and check it out inside. It's rare both sides are low. A decarb could bring it up also. I have the parts manual for that engine if you want to PM me with your email and request.

                  Yea, I'm willing to bet the compression will improve, once you get it running and do a decarb. At least they're even. You may just have sticky rings now, from sitting.
                  As for the lower unit, I would just flush it out and put fresh oil in it with new washers on the plugs. You may or may not get water intrusion after that, but it's worth a try.
                  Coils are available at your local marine supply dealer or at Napa.

                    Re: evinrude 1957 7.5hp fleetwin

                    I can see the coils through the fly wheel, but I can't get the fly wheel off. I took the nut off but the fly wheel won't lift off. I noticed a little groove in the washer around the post. Do I have to do anything with that? Any suggestions, I'm sure its something Im over looking?
