You go to a lot of trouble to make sure your viewers get to see what's going on. I appreciate that. Nice job.

[@TheGarageEngineer]

I'm glad you enjoyed it. Thanks for watching.

[@GuyLawrence-uo6bt]

i just came across an old Lightwin and did not really know where to start, but this video is a great help. Thanks

[@TheGarageEngineer]

It will be a fun project. Good luck!

[@ehomhomler3182]

It's so nice having instant pictures we didn't back in the day! Oh yeah that's where it goes! Even the Polaroid cameras the quality of the picture wasn't there. Thanks for the videos.

[@TheGarageEngineer]

I take lots of pictures when I work on a project. Because that one time that I don't is the picture that I need to put that specific part back together. Thanks for watching.

[@marksilva9188]

This is a 1967, 3 HP Model 3706, as shown @ 7:02 on the freeze plug. I appreciate you making and sharing this video, thanks

[@TheGarageEngineer]

Good catch. I totally missed that info. Thanks for watching.

[@brianchisnell1548]

Yes. 68 went to remote tank

[@WoodConcreteCreations]

Thanks for the usefull video!

[@ct1762]

just a tip: all you need is to spin the flywheel by hand to check for spark on these little ones. if it doesnt spark by hand, she needs some work for sure. those points systems are great... 90% of the time just a clean and adjust will bring it back to life. of course the coils should be replaced if they look nasty. great video hope it's running sweet still. love those angled weedless lower units!

[@davekimbler2308]

A Shore my experience is it’s usually the plug wires that go bad but I put new in all my customers motors ! From wires to coils to point and condensers along with plugs and rebuild the air fuel metering device !

[@thomastoups3451]

Hint: Before you try to pull the flywheel, put a few drops of Kroil penetrating oil on the crankshaft and leave it overnight. Makes 'em come off a lot easier.

[@vxnova1]

Very good video thanks for sharing, one note is that the dielectric grease is an insulator, it wouldn’t be recommended to cover the metal contact of the spark plug with it, it’s fine on the cable to plug holder and around the outside of the spark plug to create a waterproof seal with the plug.

[@MarcelDiane]

Awesome stuff dude!

[@TheGarageEngineer]

Thanks for watching. Glad you enjoyed it.

[@muhammadnadeem9661]

Very good service you Sir.💖

[@OutBoardTink62]

Funny to watch people who dont do this alot with the harmonic balancer upside down and bending the bolts .You have to start somewhere I guess. Makes for fun & a great video ..GP.

[@haimchandpuran7789]

Thanks for sharing really appreciate it. Great

[@TheGarageEngineer]

My pleasure!

[@blondestrainger]

Im showing my age and had one just like it when i was a boy. It is a 1958 ish not a 68. they were built very well. Easy to work on and were a lot of fun. Even put two of them on my 8 foot pram !

[@davekimbler2308]

blondestrainger my 67 duck twin is exactly the same cowl tank and ring as his ! That shape ran from 54 to 68 and the only way to tell what year is by the model number !

[@Reaper-cs7qt]

Fantastic video, sure helped me a lot. Thank you so much !!! I subscribed to your channel , looking forward to your future projects . Great quality !!! Thanks

[@TheGarageEngineer]

Glad it helped. Thanks for watching.

[@evengineering7136]

using a puller. Tighten it up as far s you feel it is safe, then tap the main puller bolt with a copper hammer. tighten another quarter turn and tap that center bolt again. (99% success.)

[@Falconar12]

Just to help you for a similar repair in the future:- The HT lead is heavy duty cable and most unlikely to break. The connections at either end however do go open circuit occasionally, and a small snip off the ends providing the cable is long enough will enable you to remake the connections. The contact breakers should always be removed and cleaned as with any of the older motor vehicles. The gap should then be reset as this affects the ignition dwell angle and hence the ignition timing. It is very important that the heel and cam of the breaker is lubricated. If left dry the cam will gradually wear and change the dwell angle/ignition timimg. However I must congratulate you on the way you managed a successfull conclusion without having the knowledge of a skilled motor engineer. Well done.

[@Falconar12]

The only exception to the HT lead is if it is a carbon cable.

[@TheGarageEngineer]

Thanks for the advise. Thanks for watching.👍

[@davekimbler2308]

Are you draining the lower unit and pressure testing it to see if the seals are good ? Those are not OEM coils they are made in Germany which are better the the Chinese coils , so someone has done work on it before . Is the float bowl gasket black or brown ? Black rubber ones are newer . And that motor runs better I’ve found on j6c champion plugs . Nice video ! I’ve been doing repairs for years and thought I’d check you videos out ! 👍

[@davidbaker3270]

all you had to do was tighten the puller centre bolt up tap the bolt head or socket with a hammer tighten a bit more and it would come off never tighten with any impact tool or wrench you was very lucky it didn't rip the threads out of the flywheel same as refitting don't over do things people get to heavy handed with spanners and sockets

[@jamestaddei9148]

Love the way ya bent the puller bolts and mashed the flywheel nut . Also like the fact that the wire really was ok and had to be replaced cause ya ripped the plug boot off ,when it was dirty points the whole time. Oh yea what an engineer!!!!! lol, hack!

[@jonhutchens9770]

You should try liquid electrical tape. It is great for sealing up electrics and protecting components. I use it on my trailer wiring.

[@curtishartog9620]

I have the same unit, put gas in cylinders and it fired up a couple times, also backfired a couple aswell, spark plugs are new and wires tested good, do you think I should proceed to put back together and move on to carburetor??? I do have another ignition from eBay but like I said the tester on both plugs lit up. Should I just change anyway? Unit was bought as project

[@curtishartog9620]

It’s all good I got her going!!!

[@thomastoups3451]

2nd Hint: After letting the Kroil sit overnight, as you put pressure on the flywheel with your puller, tap the flywheel gently with a soft-faced hammer. Tap it gently, because there are magnets in the flywheel. Also, if you see the originial coils under the flywheel, it's best to replace them and the points. New coils are only around $17 each.

[@TheGarageEngineer]

Thanks for the advice. 👍

[@Oxsunn11]

Where can I find new coil?

[@TheGarageEngineer]

I found ebay as the best source for non oem parts.

[@guyfogleman6465]

I'm thinking your prop shear pin is sheared and your prop isn't able to push the boat. There's often enough friction to spin prop, but not enough under a load. Nice project by yhe way. That motor will move that boat around 9 knots

[@TheGarageEngineer]

Good catch. Check out the other videos in the playlist where I come to the same conclusion and repair the problem. Thanks for watching.

[@adhiyyuadhikko6676]

You should change the spark plugs

[@SouthernGinger]

Pretty interesting! Thanks for sharing dude

[@TheGarageEngineer]

Thanks. I enjoyed making the video.

[@timbranon667]

I have a 1957 Johnson JW-13 3 hp boat motor that I have just overhauled. Now, the throttle lever keeps drifting on me and I'm not sure how to keep it tight. I think it has something to do with the coils and the flywheel. I'm thinking that the clockwise spin of the coils is causing the drift or creep in the lever. Or maybe there is a tension or adjustment screw I can adjust. Do you have any suggestions?

[@TheGarageEngineer]

.

[@matthewsaia409]

day late and dollar short, but if you ever have a flywheel thats stuck like that, tighten the puller to where the bolts have some pretty good tension on them and smack the center puller bolt on the top with a hammer (the bigger the better) and that will break it loose most every time

[@samuelhall4056]

good job! Pretty sure your puller was upside down. We've all done it before, lol

[@TheGarageEngineer]

thanks for the advice. i will recheck it.

[@Larrlos]

You're right good eye sir.

[@lylesguitar]

Can you show multimeter setting you used?

[@Gateman47]

this is a late fifties Evinrude weedless. you can tell by the angle of the prop which will catch and cut weeds between the prop and the skeg.

[@arnarne]

john The divine Ah, is that what the "weedless" means! English is not my first language and I actually never quite understood what weedless stood for when it comes to these little motors. Thanks f. your information!

[@brianchisnell1548]

These angle drives go back to the late 40s I have a '68 same drive. You had a choice. Lightwin or Yachtwin witch was 90 degree drive, lower gear ratio and bigger prop

[@SFtruckerWolf]

Broken Condensor loses spark totally. That have happened for me many times.

[@kentyler966]

You can find several more sites on KZbin that work on the same motor with greater detail.

[@arnarne]

Ken Tyler That is true but this is a good help too and very enjoyable to watch!

[@nicktopple6447]

Any idea on where to get one of those pullers?

[@TheGarageEngineer]

I rented it for free from my auto parts store. Or off Amazon.

[@brianchisnell1548]

Oh and they were all designed for 15 in. Transoms. A long shaft was a 5 in. Spacer between the shaft and lower unit.

[@RetiredPilot]

hope you changed both wires!!!!

[@TheGarageEngineer]

I didn't. I wanted to get it up in running then I want to do a full strip down rebuild. Thanks for watching.

[@-addezz-8516]

whats wrong? i have the same engine, very small spark in cylinder 2. i just changed the ign-coil, and changed those condensators with each other. still just a very small spark

[@TheGarageEngineer]

Have you checked the gap of the coil to the magneto? Have you tried a new spark plug?

[@-addezz-8516]

@@TheGarageEngineer i have new plugs, and no i havent checked the gap. Thanks ill go check it

It is very good. I have to fix sheer pin. But it does not have neutral speed.

do you mix oil and gas like a weed eater on these or no

[@davidgray7907]

I'm working on the same one right now and I'm not getting any fire on either one so I'm trying to figure out some watching your video to see if I can fix it

[@TheGarageEngineer]

Yes. But check the ratio of your motor. My motor is a different ratio mix than my weed eater.

[@davidgray7907]

@@TheGarageEngineer okay I wasn't sure I wanted to make sure before I ran it at all do you have to have this submerged in water when you crank it

[@TheGarageEngineer]

That's great. They are fun to work on. If not spark then you'll have to check the points. Test the condensor. I did videos on those. Good luck.
