Thank you Mike. I'm just a beginner not even sure how outboard motors function. But after this video im understanding a lot more thank you for that simple understandable explanation of what it does im looking forward to learning more about outboards have a great day Chris
Sweet another great video T mike you are helping Outbord enthusiast all over the United States and elsewhere I’m sure 👍🏻
Thank you so much for taking the time. This was a fantastic explanation.
Thank you for video. I have a question. I have old single axle small tractor Gutbrod Terra from 70th, and I need to upgrade it from point to electronic ignition. A problem is that it has flywheel with four magnets there. How can I remove unnecessary three magnets from flywheel? Thanks for advise.
So smart your a good teacher for anyone
Really enjoying your vintage videos!
realy explained love the cont I'm working on a 1967 evinrude 9.5 thanks
Thanks!
Messy buckets Mike, brilliant video!
Very good explanation
Hi Mike, I fixed an old coil that the wire broke on the inside today. One of those 1947 TD-20 backwards coils. Strange design with the magnet in the middle and not on the flywheel. I was able to solder new wire on and patch up my access into the coil. Wasn't sure if it was possible but it worked👍
Would make a great video. Great job.
I subscribed
I made one today. Will be out soon. Short and sweet👍
Hey, Thanks Buddy. Just got into these old motors and I see why everyone in the vintage outboard motor groups loves them. So nice to work on something that still uses standard tools. I plan on picking up an Evanrude lightwin someday and a PO15
Thank you for the info!!
How critical is it to have the coils "perfectly" spaced from the magneto? I have replaced all my electrics and still have no spark in my '73 evinrude 9.5. Everything's attached the way it should be but I don't have the alignment ring to properly space the coils.
Just use a straight edge to align coil with base
i just came here to find the answer you are chasing. My thoughts after seeing this man magnetise a bolt to the flywheel magnets. I think you have a good amount of tolerance seeing as though that bolt was magnetised from at least 3-5mm away?
Thanks so much.
very perfect video .
So my understanding is that the points simply collapse the primary winding's field which in turn induces voltage into the secondary winding producing an increased secondary voltage to fire the high resistance plug.
Yes the permanent magnet in the flywheel generates a voltage/current which saturates the primary winding of the coil. When the points open the field collapses in the primary coil and induces a voltage into the secondary coil which then fires the spark plug. As far as the high resistance plug these old outboards use solid wire secondary wires and regular spark plugs. The resistance is the spark plug gap which the high secondary voltage (20K plus) is able to bridge.
I bought a new magneto cam I see the another one was broke I put the new one in points gap at .020 I put it all together I go to pull on it matter fact I can’t pull on it the rope won’t come out and the powerhead moves what’s going on and the other magneto cam broke I have no idea why thanks for your help your videos are really good
Just came across your channel great videos watching from Ireland 🇮🇪 new subscription aswell 💯✅
Thank you Mike. I understood. Off Topic: Do you have over the counter matches for 1960's Evinrude Outboard colors of paint? I want to paint the blue of my 1965 5 HP "Angler".
hi mike have a Evinrude fisherman 6 hp 2stroke i have replaced the coils sparkplugs condensers good spark at the plugs points set to 20 thou , got the carb off how \ do i adjust the needle valve at the front of the carb ,have cleaned the carb out all new jets and float, .have compression could you assist me with the carb the fly wheel has 59 on the top the thing wont fire up done timing ,also put new petrol feed pipes from the fuel filter and up to the pump and to the using 50\50 2stroke petrol bowl is fresh 2 stroke getting petrol to the pump & to the carb still wont run . yours cheesed aff fi SCOTLAND Ian NEED A BIT HELP

I wonder if the magnet is a neodymium magnet, and at what strength. For my home made break disc windgen I used 24 N45 neodymium magnets. N55 is too strong and will fry my coils.
Or is the magnet in the outboard engine just a regular black ferrite magnet. Thanks in advance for the info.!
Not sure
Hey mike how do to time a 1958 Johnson 18 horse outboard
ruclips.net/video/E4R57aVGWiA/видео.html
Excellent, informative video. Thanks!
I wonder if you can answer a question for me? On my flywheel I have magnets on either side. Now it looks like one set has factory paint on them. Is that normal? Thanks🇨🇦
Mercury 2-stroke Thunderbolt egnition 9.8. Think it's a 1986 but the serial number has disappeared. Is there any other way to find out the year? Just purchased it up here in Canada for $700 . Crazy I know. I'm in the city. Anyways, I just finished the points, stator and wiring but, until I find the year I can't go any further.
Say thank you to bringing things into focus, I do have a question. I have a 1955 Evinrude 5.5hp, it starts very nicely and idles great but on high speed is lacking some power (I'm test running while in the lake.) I don't have a speed gauge but it feels like it's only doing 5 or so mph. Mind you, I have this motor mounted on a 16 foot canoe. what could be going on?
5 miles per hour is not bad for a 5 hp.
I need to locate and buy a good used Flywheel for my 1966 20 horse Johnson. Not finding one on ebay yet. Any suggestions ?

How are you able to find such mint condition parts for your motors? I'm trying to find coils for an 80's Honda b100 10 HP outboard motor. And advice would be of great help please. Thanks

Help! I was replacing my flywheel on a B&S 21hp yt3000 and dropped the key way down the hole in the crank. Using a magnet pulled it out and there is a 3/8x 1 7/8 magnet bag that came out. What does this do and it seems to long for the bolt?
Sorry not familiar with that motor
@@michaeljsimon NEVER MIND it turned out to be the magnet to my retriever tool just fell out. Boy do I fell STUPID!
Wow, very useful. I’ve been restoring a 1955 Evinrude 3hp outboard. I’ve been having issues with the ignition system. And this was perfect timing. One question I have is how do you know which coil goes to which cylinder?
Actually I have two questions. I’m assuming the coil should not make contact with the flywheel and that there should be a gap between the coil and the flywheel. If so, how do you know when the coil is positioned properly?

@@michaeljsimon T-Mike! Thank you! Very great explanations for a new vintage outboard engine mechanic. I’ve only got one. And it’s been sitting for 40 years. You’re helping me out a lot! Cheers from Wisconsin
Hi. My friend helped me change out coils, points, condensers and plugs- when we go to put the flywheel back on and try to crank motor it seems to be hanging up on something or wanting to take like the throttle cable or spark plug wires with it? Something seems to be binding? Its a 1968 6 hp johnson- any help would be appreciated! Now we even switch back coils to see if that made a difference- clearance wise. It did not. Thank you
Magneto is in a bind. Remove flywheel and try to move magneto. It should move freely.
Hi. Thank you but not sure I understand how it moves freely if its bolted down?
The motor or magneto does turn by turning over motor by hand- thats how we set the points gap but when we try to put the flywheel on it seems to be binding or hanging up on something
@@tooltime9260 Hi. Thank you! My neighbor and i got it going with some help from people like you on utube. Took it out for its maiden voyage last summer. It ran well but haven’t ben out this year-recovering from a surgery. Thank you for your help and for the laugh as well. Have a good night
i followed all your instructions and rebuilt my magneto , 6hp 68 johnson, now the flywheel wont go back on a spin freely, any ideas?
Check woodruff key
@@michaeljsimon woodruff key good. I have concluded that this year are coils just don’t fit so I’m sending them back to get the OEM coils
Sierra coils
Hey T mike, I got a 71 johnson 9.5 and the cam is wedged on the camshaft and doesnt come off. Any suggestions?
Is the woodruff key damaged?
Pictures please
@@michaeljsimon not that I can see, just looks like the cam is pressed down further then it should be. I'll upload a picture right now
@@michaeljsimon I cant seem to be able to upload a picture but the woodruff key doesnt seem damaged. Cam just has no movement on camshaft. Seems wedged or pressed on to tight
@@brandonhamilton3766 I would spray lubricant and tap on cam and woodruff until you can pry it off. Good luck.
hi there tmike ive got an old 71 johnson 25hp ive gone through your vids and others and just cant seem to get a very good spark , new points condensers coils even spark plug wires , i can get her to fire up but just doesnt feel quite right , ive compared the spark to a friends 25 evenrudes and yes mine is not as bright , ive checked ground , set points with timing tools just like yourse and even voltmeter, the flywheel looks fine but is there a maintance that get done to them , do they go bad ? could really use some advice your neighbor from texas .
Yes flywheel magnets deenergize - test magnet with a screwdriver. You can measure magnet strength with a Gauss meter. I will make a video soon
@@michaeljsimon thanks if by chance it seem weak can it be fixed?
@@regio81 yes. They can be recharged. Try google for the process
@@regio81 Magnets that have lost their strength Sometimes you can recharge a magnet that has lost some of its original charge. If you can find a very strong magnet, repeatedly rub it across your weakened magnet. The strong magnet will realign the magnetic domains inside the weakened magnet [source:
Here is the Gauss Meter for measuring magnets in flywheel.
