I picked up a 9.9 johnson from the 50s! found it on the side of the road seized up and with your method, I brought it back to life I couldn't believe it thanks!

You seem like a very honest and hard working guy...good job! Thanks for the video.

Your a good teacher. Easy to follow, clear, to the point. Thank you for increasing my knowledge of outboards.

Excellent ... kept me at the edge of my seat.... outboards are just that way... go in for one problem and end up fixing another... Thanks Stew.

Your vids are always inexpensive ways to fix neglected or minor abuse issues. Lawnmowers and chainsaws were my into to the fixing world. Never did it for a living, but always enjoyed the adventure of figuring out what happened. Cheers

It worked! I seized up a 35 merc. Used PB Blaster and Marvel Mystery Oil as I figured I needed every advantage possible. Let it sit 3 days then very gentle back and forth with the breaker bar and it broke free. More oil in it for another 24 hrs, few more spins then set it up to start. Shocked when it fired up. Great video! thanks so much.

Thanks for this. Just bought a 1966 6HP Johnson that is seized, though it was supposed to be a busted up starter pinion gear that I bought unexamined for $100. Never used or worked on a 2 stroke before, so your videos have been very helpful.

Thanks Dangar i have a 20 hp 2 stroke Yamaha and im learning so much from you.

I purchased a 5 HP 2002 Yamaha for $50...yesterday...it was seized...never worked on outboards in my life..found water in the fuel tank...took short breaker bar and kept working it like you described without much pressure, kinda snapping it lightly, shocking it, and in 10 minutes had it un-siezed and had piston turning smoothly with spray solvent...your video solved the problem...! Thank you so much...Carb is missing so I'll need to source one...Motor looks to be fairly simple to work on since one cylinder and 2 stroke. Now I can check for spark, and compression...I've worked on lots of 2 stroke chain saws and motorcycles...this is kinda fun!

Just want to say you have saved me hundreds of dollars with your videos to be able to do this stuff my self instead of paying a Marine shop is awesome stuff! Ty Dangar Rebuilt my carb's and new seals in lower unit thank's to you buddy!

Just getting started on this video and loved the comment about never working on a boat without coffee.

I have a chance to buy a 1970s Johnson 9.5 hp outboard that is frozen for $40. After watching your video, I thought to myself "What do I have to lose?" Thanks for taking the time to explain everything.

Very helpful, my boat sank as she was moored up wrong.. she was sat under water for about 4 hours every tide for 2 months before I was able to remove the engine, got he in pices now wish i had seen this before compleatly stripping her down to just the power head. Gives me hope she will live again with out the hassle of sending her off. Thanks from the UK.

My son bought a johnson 35 hp that had been seized since 2008. We followed your video step by step and it worked like a charm! Awesome!

Another wonderful video in which I can hone my skills in the world of outboard mechanics/repairs. Thanks Dangar!

Just brought me a seahunter 4meter with 25 mariner don't know much about them but your videos are a great source of information for me as this is my first tinny thanks for great videos

Thanks! I'll need to get a Dangar Marine sticker for the cover of my Mercury 9.9 because it is running thanks to you and this vid. I really appreciate your vids. I have to listen a couple times cause I always miss something the first time and each bit is helpful.

I love your videos and have learned a ton from them! There's always another way to do anything, and sometimes another way is better! I once had a motor go under, while tied up to the beach. the transom was facing the small waves all night long, and the bilge pump failed. The small amount of spray from the waves hitting the back of the transom accumulated in the boat during the night (while I was busy drinking far too much beer), and the hull filled up with enough water to sink. So, about 10am the next morning, hung over and still sleeping, one of my drinking buddies from the night before, stopped by my camp and woke me up asking, "Hey, why is your boat under water?" I hoped that he was kidding, but he wasn't. (There's a lot more funny details that go along with this story, but I'll skip to the reason I'm writing this in the first place.) When I was finally able to get the boat back onto the trailer, I took out all of the spark plugs, the air box from the carbs, and just shoved as much fresh water through the engine, that I could from the hose. Spent about 45 minutes douching out the entire engine. The starter actually still worked and so I sprayed 4 cans of WD-40 into the cylinders and the carbs, while cranking the motor and running down 2 car batteries in the process..., and created my own Haz-Mat scene! (Helpful Hint: Don't try to remove a full sized battery from a boat, STILL submerged in salt water..., it really tingles!) It was a week later that I was able to start tearing down the engine, and found ZERO corrosion! Moral of the story..., if you can't do anything else to a motor which has submerged, except flush it out with fresh water..., DO IT! And don't worry about getting anything wet, cause that's already happened! God bless the man who created WD-40! YanceyMan, west central coast of Florida

Stu, my 2.5hp Mariner for the dinghy had a do over recently, (brother in law fell over in shallow water with canoe :) Anyway, opened the 2.5 hp up after a year due to bearings (suspect) could not find the proper bearings with the pins locking the bearing, I used ordinary SKF/FAG bearings to replace it, seals were ok, (could not find them locally ) motor runs perfect, carb inlet had a small piece of gunk (restricted inflow) making the motor fail after 200m or so, after the carb inlet cleared , all ok, fishing the estuary having fun. :) Remembered your video, cam e here to revisit it, thanks. Johan

My Suzuki DT40 looked like it seized up when on the water today & when i got it home i took the pull starter off & it was the issue after all, Thank you for your great video as you saved me some cash getting it looked at.

Watching your videos during lockdown has kept me sane and I've learned so much. Very well done.

thanks for the tip on water pump in foot not being self priming. Cleaned all the trash out from under the new pump last owner replaced..put in me tender and she pumps..you the man

Thanks for sharing this information. Just got a Yamaha 30 going by doing just this. Luckily I only had to let it soak a few hours but man it was stuck good. Funny thing is, is it was not running for years until last summer when I got it going and it started no troubles what so ever, but then after sitting for 12 months it had all seized up

I'm getting ready to fix my 90's model boat and evinrude 115 thats been sitting for 15 years.I have watched almost every video you made,and that gave me the confidence to do it. I'm sure i will be asking some questions later on, and film a bit you can use on your show, for the what not to do sections.If it works i'll send you some beers.

shouting out dangar from all the way in the Caribbean. . your a real inspiration.. keep it up

I bought a 67 Starcraft fishing boat with a non-running 1959 OMC/Gale Sea king, didn't think I would get the thing to run but I started at the basics, there was compression, so I went onto spark.. no spark, checked out the set-points, they were filthy but nothing too terrible, no holes or cracks, eventually timed those in just by using feeler gauges, spun the flywheel a few times an saw that I had one cylinder sparking and the other no spark, so I picked up a tuning kit online with new condensers and set-points, replaced all ( keeping old set-points as spares, ) .. spun the flywheel again after getting her all back together an bam, spark!.. just threw the recoil back on, a filter on the fuel line ( rusty can will get a new one ).. after a few pulls an messing with the low speed needle on the carb she came right to life and sounded beautiful!, The very next day i found a guy selling a 57 sea king WITH ELECTRIC START!, unfortunately its seized, and missing the throttle rod from the motor to the throttle hinge, but for $25 i felt it was a steal, I'm going to try and restore the electric start system an swap it onto my running motor, and just part this one out, I don't feel its worth it to try and get it running may just be too much time and money, especially considering its 60+ years old and I have no clue how long its been sitting - it was picked up at a site that was being demoed and excavated out in the twin city area of Minnesota. Long story short, I rebuilt most of the ignition system on my 59 sea king, and got her running - first little restore project of mine, this is the first outboard / boat I've ever owned, and now I'm addicted ;).. Definitely going to subscribe to your channel and keep watching! Thanks for making these videos!

OMG man I just got done doing this to my 1978 Evinrude 70hp. Such a helpful video. Spot on as usual. you are the man. Neeed to clone you and set you up in my back yard and make tons of $$$. This was the issue with my Evinrude except I had outboard 2 stroke oil lol. Thank for your time and effort in these kinds of videos. You Rock!!!

Try 50/50 mix of ATF and acetone. It's commonly used for seized pistons on old engines that haven't been cranked for 30-40 years. Fill the cylinders and let them set in the hot sun for a few days. Shouldn't take nearly as long for outboards.

Love the video, had my engine seized up and got it fixed up. Waiting on parts to get her al back together and see if she starts! Saved me money and time for sure. Thanks!

Not only was this video informative and a pleasure to watch...you seem like a really nice guy.

straightforward and uncomplicated videos cheers from the UK

Good techniques. I inherited two vintage outboards when dad passed. A 1957 7 1/2 hp Johnson and a 1980 Johnson 10 hp. Both bought new. They have not fun for over ten years. It will be fun to get them running and use them on my dink. I liveaboard on an Ericson 35 and always in need of a tender that can run me into shore when anchoring out. Thanks for your site.

"Never fix a boat without coffee." Reminds me of the blokes on Project Binkie. Lots of tea and biscuits !

This is very best video that it helps me to understand how the engine works. By watching this video I have a fare idea to help someone.

Had a motor like that never was unable to unfrozen it. Rebuilt it complete. THANKS ENJOYED IT.

My Suzuki DF 150 seized at slow speed due to having water and black, thick sludge in lower unit. Got towed and loaded on trailer and drove home. i had to drill out ( bolt extractor) drain plugs of lower unit, flushed with ATF. Installed new drain plugs and gaskets, refilled with gear lube. Ran on Muffs and hose, drained again and filled again.Also changed spark plugs, engine oil and filter, greased up drive shaft, new impeller kit. Motor runs perfect ever since. Wondering how that is possible, not having any damage. BTw , you are brilliant man, very informative and entertaining.

They could take every channel off KZfaq and I'd have all I ever need with these videos of your man. I swear, it's like a very entertaining college course. Bless you for your time and especially for sharing your knowledge. I'll be donating or joining soon, whatever you got to off I'm good with. Thanks so much bud, great video

I had to come on here and say THANK YOU. Not for me, but because you answer peoples questions. That's really cool. Dave in Pennsylvania

Just wanna say that I had a similar problem on my own outboard and this 100% worked!

I AM VERY APPRECIATIVE OF YOUR VIDEOS...CHEERS MATE FROM AMERICAN SAMOA.

Hi from NZ. I loved your coffee jokes. I'm the same with my coffee usage kick-starting the day. Great video. You give me confidence to have a go at getting an old 85hp Evinrude going! Thanks so much!

ATF fluid is good to remove contaminants and also protects from corrosion. We use it on my mate's race engine liberally on a towel to scrubs away the carbon ridge at the top of the cylinder so we can remove the pistons without terminally damaging them. Not alot of people give thought to this process. But the stuff is great for any clean up work during a rebuild to remove deposits and inpurities. You can leave it right there when you reassemble the engine, it's not going to hurt anything. I think you could also benefit to use it to get the build up off of things like hydraulic rams, stubborn shafts inside your engine when you want to pull the gearbox and as an all round corrosion inhibitor that doesn't wash off in a minute like WD40, Just as a good going over with a decent amount with a rag on all exposed steel surfaces every time you bring the boat back in. Just a suggestion, I'm not trying to control you or anything man.. A friend said his old man used to work onb Cadillacs in the 60s and many cars would come in with noisy lifters (as they sat more than they drove and the maintenance wasn't always kept up to spec. Anyway, his solution was to dump out a few litres of oil and replace it with ATF and leave the car running outside for a couple of hours, he then dumped the oil and replaced it with fresh stuff and he reckons they were quiet as a mouse after that. Food for thought. I've unseized engines by putting a mixture of ATF and WD40 down the bores and leaving it for a day or two and then trying to see if I can turn it over by hand and rock it back and forth past the point of resistance and slowly keept repeating until it feels normal again. i havent been let down by this.

Many thanks all the way from Arizona for this super helpful video! My ‘85 8hp Johnson has been great but seized up and I was so bummed .. thanks to this video I’ll be on the canyon lakes shortly escaping the ‘Rona!

Pretty versatile workshop. You can bring your car and boat around and have them both serviced while you order Chinese take away or eat in at the Van Lee Chinese Restaurant, which presumably is within a stone's throw away...

Thanks for this. I was prepared to pay a guy a bundle to look at my motor. Cheers! 🥂

Wow. A tutorial video on KZfaq that actually is helpful. Who would have thunk it

My motor has has sat up for 6 months went to mess with it yesterday and found it to be seized. Going to pick up some ATF and acetone and hope it works. Thanks for another informative video

You just saved my fishing trip with this video! Thank you so much! I just pulled the spark plugs, sprayed wd40, waited 10 minutes, applied light pressure both directions (2 stroke motor), broke free with no problem! We were about to be screwed for fathers day weekend! Thank you so much from Texas!

Best. Comment. Ever @4:10, this is my motto also-cheers!. Have the F100 torn down as far as I need to as the sump oil was milky. Found the head gasket was shot around the top cylinder (probably from blocked water ports/channels causing high block temps) and the Sump was heavily corroded. Just waiting on parts now- hopefully they arrive soon so I can assemble before I forget what went where!

I’m going through the exact same process with a Yamaha 9.9 2-stroke. Outboard was in a storage shed during a river flood and was submerged for several days in fresh but muddy water and this is 4 years later the first time the cowling has been removed even. Going on 3 days now of filling heads with rust penetrating spray and injection oil but no give at all yet with pry bar. As mentioned in video though, I’m not forcing it to the point something will break but applying plenty of force. 🤞

Just had to say something. Thanks for your time and efforts. Thank you for the education......I have a 99 johnson ocean pro 150 so your videos were extremely informative for me. Keep up the good work my friend.Cheers!

You give me motivation to try to work on this motor now🤣🤣

Great video. Thanks for all the information. I’ll be going thru your videos to see if you have any broken upper spline removal in powerhead.

i really liked the way you summed everything up. instead of using boat college terms lol. this has happened to a motor that i picked up from Indiana and brought it to my home in Colorado; It's a very high humidity place in Indiana and very hot and dry here in Colorado. so second time in the water here and the motor seized. so thank you very much for showing me i can do it myself.

Thanks! Helped me get my Nissan 2 stroke freed up. Fortunately it wasn't nearly as bad as the one in your video. I used 2 stroke oil instead of ATF. Worked like a champ and started on the 4th pull after new plugs and lower unit oil.

I love being on the water. After watching your videos I want to go buy a bunch of old, non-running engines and do the miracles you show on video. If only it were actually that easy. :) Wonderful videos. Hope you keep making them.

Stu.... Been watching your videos for quite a bit of time now! I really appreciate your detailed info/suggestions, humor, and real world experience when working on things! Working on mechanical things like engine/outboards, boats, and vehicles are a passion of mine but not my daily "profession", so it's nice to get all of your experience. Its def helped me fix some outboards lately! That's not always something a college or manual can teach a person. Subbed and will be getting some swag!

Very nice video. One tip you may like, is to add about 25% acetone to your tranny fluid when using it as a penetrating oil. I learned this from a machine shop, and it really makes a big difference in how well and how quickly it releases frozen parts. Good job on bringing that motor back!

Some years back, a friend gave me a 6hp motor. Said it was seized up. I thought what the heck, I'll play with it. Got it home on a pretty nice wood engine stand that he had it mounted on. After 5 min, found that it was in forward gear, and the prop was hitting the bottom of the stand.

very well explained! thank you. subscribed just got handed down a 1969 6 hp Evinrude and a 1934 1.4 hp Johnson cant wait to play with em

Thanks for all your videos! I am learning so much from you and I'm currently trying to get my 48hp Evinrude up and running again. Shaka all the way from Hawaii!

My Johnson 30hp is stuck so I'll give this a try. I forgot to install a spark plug back a few months back, must have been distracted by my kids :( and the piston is seized from moisture getting in. Thanks, the video was very informative.

Great videos man. Love your work ethic. You explain everything in detail and make it easy to understand. Subscribed! Jack in the USA

You do some good videos mate. You work like I used to in my time off before I lost my motivation at home on my projects. I get a little tired of it working with vessels all day everyday as a marine engineer on my time off.

Great thanks. I've actually ordered a second-hand replacement for my seized BF20 but will have a play with it this afternoon :-)

You sir are a genius. You deserve your own TV show, awesome videos brotha

Man, this is a great video, Stu--this one (and another) made me a subscriber.

The video was very well done and helped me with other outboard motors as well thanks for sharing It very much appreciated.

Way to work through a series of problems !! Excellent !! thank You!

Thank you!!!!! Saved me 500 dollars, love your videos

This was an amazing video! Watching from Canada! Thanks for all the tips. I learned a lot.

I subscribed because your videos are easy to follow and you seem as true blue as they come. Nice work and thanks.

i did what you did and it worked thanks i am going fishing now

Thanks for your training. I've got a post hole drill, E85 Earthquake, that locked up on me by surprise. Was running and seized after shutting down. No restart. Huh. I never forget oil in gas so go figure. I'll try your method soon. Short blocks aren't cheap.

thanks you for the video it was very helpful to me my. Out board is sucking air so I think I can fix the problem now very good and helpful

Great video! Nothing is off topic, it's all a process and teaches the basics of going through the motions when it comes to these small engines! I would've almost been tempted to inspect the bore walls but I'm sure removing the head cover would've required a gasket replacement or something along the lines of not being worth it. PS: Is that cheeky beverage at @ 6:49 I spot!

That satisfying sound of success!

Great informative video as always, thanks. (from Scotland)

Great video .and thanks for going though the carb aswell.

Well Done Dangar great video and good to see an Aussie having a proper crack. Complete with dry humour on the “Sounds So Dodger comment” it took me a second to get that one :)

I've learnt so much through watching your vids. Keep up the good work. Thanks!

A seized engine like this may be gotten started but it will never be quite right until the pistons are removed and inspected and most likely the bore needs to be at least honed to remove the pitting from the corroded rings,and new rings installed. This is a stop gap measure.

That's some great service!! Worth every penny!

This is very helpful and you’re a great teacher, thanks for the advice and I’ll try it on the motor I just got that’s seized up!

Love watching your vids very educational, direct and easy to understand. These will and have helped me to carry out my own mechanics to my mariner 40. Cheers dude. Vince from England.

Thank you learnt a lot cheers from Scotland U.K.

Good sense and a careful mechanic . New Subscriber.

Worked for me , got me out of the shit on ice skates , miracle , now she runs , I didn't have probs with the fuel ⛽️ just the seized up bit , after buying a engine and not even trying to pull the cord before I paided up , big mistake , seller was on board the whole time for refund , but with your video it all came up trumps 🇺🇸for everyone 🇦🇺

although I do not understand English but I like to see your video explain very much

Your videos are soooo good man such a good teacher man iv watched so many of your videos and they are very good

Nice video, Reminds me of when I was a kid working on 2 stroke motorcycles. im 50 now and still a kid hahaha Great vid I love engines and anything mechanical, just don't like the greasy hands anymore.

Good advice. And agreed. Never try to do MUCH without coffee!

Great info, honest and practical! Thank you!

hi how are you, buddy? I am Luíz do Brasil, and I follow all your videos, I learn a lot, they are very good, congratulations, God bless you!

Good work and thanks for sharing your idea about that motor....

Try adding an equal quantity of acetone to the ATF, it is the most effective freeing agent I have ever found. Love your work, Stu.

Love the videos! Thanks for taking us through the steps. Got a 25 I'm about to tackle. It's good to see how you do things and hear your thought process.

support 100% on this side. Good Job! Danger

Wow, you rose the dead there! Bloody good effort.

Enjoy your videos. You’re a regular guy.
