This guy has no idea how much he helps people and how much these videos are appreciated. If you can’t do work your self boating is hardly affordable for the middle class. Your a saint honestly thank you for your expertise you have no idea how much it is appreciated. Keeping men’s wife’s from putting for sale signs on their boats. Hero!!

I am a new boater, my first time trying to gear up my new inflatable boat . I went and bought me a used Yamaha 9.9HP 4 stroke off of some folks that swore up and down that it is a great motor and they ran it just last summer and don't need it any more . I have never seen an outboard close enough to even know how to start it so of course i never tested it when i picked it up. So long story short i took a challenge up on my self an decided to take a look inside and learn my lesson. The engine looks spotless as it is brand new even though it is 1989 motor. I came to understand that the gear box was seized up , when i took the lower unit down chunks of salt and sand mixed in with shells fell off it , at that point i wish i saw your videos before i got my hands in it , I had real hard time getting the old parts out , i watched hundreds of videos and nothing . So like you said i did put some scratches on a main shaft as i was frustrated with lack of knowledge and tools. And just yesterday i watched couple of your videos and it was like thank you God for sending me this guy. Thank you , you are a great teacher and doing this from the heart. I appreciate, and looking forward on getting my baby in good shape with your help. So long brother , keep doing what you doing.

I normally replace my sea water pump oil seal every year due to leaks (corroded spring ring in seal). Since i followed your advise to replace the spring ring with rubber O-ring, I've never had any leak these 4 years !! THANK YOU Dangar Marine.

This is a Man's Man and can do anything using nothing if he needs to. I really like your style, and you are very modest and down to earth. You sir are the guy I would want on my team when in a rough spot. Keep doing the videos.

Right!! I have no idea of ​​mechanics, but watching your videos I almost encourage myself to do anything simple.. Thank you very much for making our lives a little easier! Greetings from Valencia, Spain! 👍

I can not thank you enough for this among several of the other videos you have made!!! The knowledge you share has been the difference between my lil girl having memories of a summer filled with days and days of fun on the lake vrs boredom at home! THANK YOU!!!!!

What I did in the past ... Go to your local hardware store and find a long self tapping screw (sheet metal) find a small tube that screw will fit inside but also large enough to fit between shaft and housing.. Place tube, insert a long screw into the tube and rest should be self explanatory.. Good luck my fellow weekend warriors...

Thanks to Dangar my old boat and engine are self serviced for potting and fishing now for 25 years in Donegal Ireland. Good practical stuff - good luck and keep going!

Dangar,what makes a good mechanic is knowing what tool to use where.What makes a great mechanic is knowing how to rectify a problem by any means he can. Again a great video mate. Fabian.

Thanks for the tip and offending the "purests"!!! A lot of those guys don't understand that not all of us can afford $200 tools for a one time job and we know how to be careful. I will keep watching. Please keep the videos coming!

Sometimes when the carrier is stuck...it'll take HOURS to get it out...."IF" it can be removed! I've used this method on other applications....IT WORKS! Thanks for sharing

I love your videos. I get on forums and guys act like it is no big deal to drop $500US on a new VST. They defend the manufacturer like they are family. You have 100's of people having the same crack form and they try to blame it on the people. You seem very real. Buy stuff when necessary but aren't afraid to make stuff work.

Fantastic video for the real world DIY guy! I’ve learned more in 1 week watching your videos than in 2 months of reading manuals. Keep them coming, outstanding information!!!

I am a new outboard boat owner and I thank you for all your help. I was able to fix my lower unit myself. You are a great teacher...

I am changing the impeller in my 1984 35hp Evinrude. When I removed the old water pump housing I touched the underneath seal and the spring broke. I'm in a time crunch and did not want to replace the seals now. So I was looking for a suitable replacement for the spring. What a great idea to use a nitrile O-ring in place of the metal spring. Thanks for the video.

I’m always impressed with your videos. You always explain things in layman terms and they are practical uses for everyone, and very detailed. Keep up the good work my friend.

Really like your videos. I've worked on everything mechanical all my life, car, boat retired aircraft mechanic. Your knowledge is evident in the way you explain your tasks. I agree 100% with your discription, the book only shows one way, the art of a real mechanic is how to work on items when the "book way" will not or does not work. Thank you for your ability to explain how to accomplish tasks. Have a blessed day my friend.

Good work, so refreshing to see a real bloke doing real repairs, for the real world where it is not always perfect. I am so happy to be able to go to your videos, they are a great help for anyone looking to do a repair/mtce. The marine environment is so hard on all parts that when things break it is not on flat water sunny day near the shore line.

Good basic informative vid,and easy to follow. No Premier movie boring flashy introduction,and advertising. The advise is excellent. Helped me enormously!!

best u2ber teacher ever!!! Thank your so much, for all your expertise and help.

I've been pulling seaks for years this way. Between not having pullers, seized in place. Get er done. All the way from Australia to see other guys working with same attitude, thanks.

I really appreciate you are taking the time to make visible the areas you are referencing. It is very helpful to be able to identify the exact point you are describing, while others DIY videos can assume that people will know exactly what they should be seeing. I came in to 2 Evinrude 15hp motors (one running and one for parts) at the end of last summer and I'm just now getting a chance to look in to them. I look forward to doing my best to make this a 1 or 2 pull effort when I'm on the water wanting to instead of struggling to get it started. Keep these videos coming!!! Thank You

Finally got around to replacing prop shaft seals the hack way. Worked great no damage went back in perfect. Thanks for all the work U so on Ur videos. Much Respect!!!!!

Brilliant, honest......practical. These are the types of people that save lives in war, win races at baja and keep future generations of mechanics interested in helping strangers get their machines back into service. Brilliant

Very Very Impressive, and immensely helpful. Based on your tutelage I have rebuilt an '85 Yamaha 6HP a 1964 Evinrude 9.5HP, and now working on a waterlogged 14' 1985 Vontage using most of the Dangar vids: from trailer bearing replacement, to carburetor rebuilding, and oil seal replacement the hack way, and everything in between. A newbie to anything to do with motors or boats, I am on my way to resurrecting a mini version of the blessed GreenMachine! Your meticulous camera angles, tripod placements and all the special treats like how you cutaway the gear case for "How an outboard gearbox works". Thanks so much for your gracious guidance...carry on warrior Stu ! ~ doug, vancouver canada

14:46 I actually quite literally felt like I was hangin with you outside the shop sharing a beer talking motors. Way cool! Thanks for the vid

I am SO GLAD I found this! I've looked all over trying to find a way to do this myself and everyone has these specialized tools! I'm SO GLAD I found this before I nicked the prop shaft!!!! THANK YOU SO MUCH from North Carolina USA

I just bought a dinghy with a 25hp Yamaha 2004. I knew I needed to change the seals as there was some water in the lower unit. What I love about KZfaq, it allows folks like you to present options to having factory techs. I'm very impressed with the way the you Teach that this isn't the ideal way to do it but an option and not to do it if you fear nicking the prop shaft. Great Job as a presenter and Teacher. Thanks and i'll be looking for more of your videos.Capt Steve Russell

Can't tell you how many times you've helped me save tons of money.....6 months ago my most extreme mechanical feat was replacing spark plugs, and doing oil changes.....Thanks to your help, a specific service manual, and maybe a little bit of other videos (bit here, bit there) my F90 is in top shape. I have removed, disasembled, repaired, and replaced my entire lower unit assembly, which includes a full set of replacement upper and shaft oil seals, water pump replacement as well as completely servicing my fuel system (from tank, to low pressure pump, VST, intake, and injector servicing and cleaning. You've easily saved me over $1500 on labor costs. THANK YOU

Love your vids mate ! Awesome showing people ways to do things in the backyard without fancy tools or equipment in a way that shows corroded real life scenarios you always explain things very well and get good close ups of what's going on ! Legend mate ! I'm sure your vids have helped more people than you know !

As a complete novice at fixing ANYTHING, I used this hack and was able to remove the oil ring. It took a couple of days and a bit of courage, but it came out successfully. Thank you for the tip!

Thank you mate.. your a true aussie that is helping Aussie battlers stay on the water...with reliable and not leaking gear oil in our waterways...much appreciated mate..thanks Burnsy

Thanks so much for this video (and the others!) I have no mechanical experience but I am handy and I can definitely do this. I was worried about spending more big bucks on an older motor and I now have the confidence to do this and some of the other maintenance from your other videos. You're an excellent teacher. Keep them coming.

Thank You Sir !!! Your video just saved me close to $600, because thats what local Yamaha dealer wanted to change oil seals on my Yamaha 225 OX66. Keep them coming, fantastic work you are doing.

A lot of great tips and very solid experience based information

Just did the same job... Mariner 82 model. got some scratches in the inner metal ring. Gonna put inn new unoriginal oilseals there now since they don`t make it anymore. The local Yamaha dealer don`t even sell any parts to new motors here. No money to be made...

Thank you so much for this, I used your technique to replace leaking driveshaft seals in a 2011 250hp Evinrude ETEC, once I had the holes drilled I pulled the seals with the barbs on big straightened fishing hooks. When I inserted the new seals I placed an old seal on top of the new one to protect it, then cut a length of three quarter inch pvc pipe to fit over the driveshaft and hammered the top of the pipe to get the seals down. The gearcase bearing housing on my ETEC is PRESSED, so practically impossible to remove and replace for work without the specific equipment such as a 10 tonne floor press... I really dig your style dude!

Always love to watch your experience play such a important role in repairs.....

I don't even own a boat, and I'm loving these videos. You're a great educator. Love your style and technique. Great stuff.

The right way to do this job is the way that works. Brilliant use of an "O" ring to replace the spring. Thanks for the vid!

Thanks for this video. I'm in that similar situation with my yamaha 50 oil seals. No trailer board or number plate to take it to a mechanic, mechanics cant come to me as they say "only in house"...this is the way im doing it...got the outer seal out this afternoon. With the assistance of your videos ive been able to do a lot more than i would have been able to before, and help when a mechanic hasnt done the job right or conned me....to get engine back working fully again....been let down twice in the last year by 2 mechanics and will i hell tow 100 miles each way to take it to someone. Very much appreciated videos and information...the best videos for marine services on KZfaq

Again thank you for this tip. I have run across many of the bearing carriers that were seized up and couldn't be removed, and many times I just bought a used lower unit on Ebay that cost several hundred dollars where I could have used this technique and saved all that money...

Thank you for giving me some confidence, to change the prop seals on my 1976 20 hp mercury outboard. THANKS FRIEND

love your videos. Your teaching style is perfect. Wish I could spend a couple months in your shop watching you work and learning. Thank you for your videos

Used this technic today on a 86 40 hp Johnson worked great I wrapped electrical tape around shaft incase of a slip all is good thanks the punch making the hole is critical.

Man oh man, how helpfull was this, couldnt get the castle nut removed on a 150hp 2 stroke yamaha and your way worked a charm. Salute

Thank You for the video. The insertion of the new seals were pretty quick, you might have mentioned that the inner seal lip faces the bearing and the outer seal lip faces out towards the prop. The inner keeps gear oil in while the outer keeps water out. Ken

Thank you for your videos. You are definitely a working man’s friend. If I’m ever in Australia, would like to look you up and shake your hand.

This is an awesome piece of advice. Thank You! My boat is a 1990 Chapparel with twin Volvo Penta 350's (chevy small blocks) and DP-a out-drives. I'm sure the original owners never even picked up a screwdriver themselves. Still stout, this vessel requires a decent amount of TLC to keep her sea worthy. When I saw oil dripping from the prop shaft after we pulled her from the water in November I thought that would be the last season for the old girl. Your video gave me confidence that a $2,000 job could be done for the price of the parts $30. You are worth your salt mate. Thanks for this video please don't stop producing them. If you ever get to the state of Connecticut in the US look me up dinner and drinks on me!

Great video, going to tackle oil seal on my 94 yamaha C 40 elrs this week. i look at your video's all the time. Thanks

Although it was not probably ideal, but you were correct in showing a different way to get to the same place. I for one really appreciate your efforts!

I really appreciate all of your videos. You make it look easy. Thanks

Thanks for the tips---Ill be working on mine soon. Delicately. Thanks again mate.

Still helpful!!!!! I justs done one this way,AFTER watching you do it; Thanks very much,DANGAR MARINE; you have the power,lol

Thanks for your videos. I'm about to step into the world of outboards (two mercury 150 1998 two strokes...) and these have been a great help. extremely well explained and down to earth. Again thanks for taking to the time to share your knowledge. good on ya !

Quite clever with all appropriate caveats....excellent!! Learned quite a bit, thanks!

Great video! Love how this guy is low key drinking on that beer 🍺 after a job well done! 😂👌🏻

I totally agree. Mechanical stuffs not always works as we expect so you have to be able to think further and use some rough technics. Thanks for sharing

Stu ... keeping it real. Great explanation, video, audio. If they had an award show on youtube, you'd win many awards.

Thanks dangar your are a real world mechanic!

Some of your videos have saved me a lot of time and money. Others are really interesting and I always learn some new trick or two. Thanks for this great channel!

Great explanation. I used it on my 99’ Honda 50. It saved me from having to buy a new motor. Thanks very much

Although this is a little dated, it has been an INVALUABLE bit of information!

Dangar I for one am most appreciative to know a few tricks where necessary, in a pinch. Thank you

Nice video my man just what I was looking for. Keep up the real life tips not every job is txt book like you say. Thanks for the help

I thank you very much for the videos you make, you show us that there is more than one way to do things, and the potential risks involved, makes the toll on our wallets a lot less. Would like to shout you a box someday.

good video Danger I'm waiting for seals to arrive so can have so fun too. thank u. I'm feeling more confidence of doing this ....

Hi mate, I find your videos really really informative and so easy to follow! thanks for putting in so much effort.

I usually drill two small holes into the metal part and them put in metal screws to pry the seal out a bit at a time and found it works fine.

Massive help to all hacks usually initiated by pros no subsitute for experience he makes life easier for us all thank u

You are an invaluable source of solid information, many thanks for taking so much time to share it with us

watched a few of your vids now,now doing all my own work on my outboard,thanks heaps

we've come across the seal housing area very corroded but otherwise in good shape and used a freeze in (interference fit) sleeve after a ream of the area and abit of sealer, good as new. your video is spot on for those corroded in carriers also.

Once again, you made an awesome video that made me an instant 'mechanic'! Thank you.

As a fine marine mechanic you are intelligent and aware . I would totally true you with my 25 hp 2 stroke 2008

I love the realistic approach mate. Keep them coming.

Great videos! I like your style. This is also a great technique for a guy who is handy, only spent a few hundred dollars on an old motor 12 years ago, and does not want to spend $1,000 dollars replacing the seals now. Thanks you!

you are a good teacher,thanks

Another great video from Dangar Marine. Thanks

HI there from NZ. This a seriously valuable video. Thank you taking the time to make it. I have a engine rebuild coming up and this video is bound to come in handy!

Thanks I'm gonna be using this method taking out the seals.

Excellent video. I learned a lot with the close ups and explanations in detail. Awesome channel 👍

This convinced me to stay with outboards with removable (slide out) gear assembly.

thanks very much. Am going to have a go on my 1995 mariner 15 prop shaft seals.

Hell with going to boating school to learn to work on motors this guy is a great instructor

Thanks Dangar, I take my hat off to ya mate! I have an old 1972 Evinrude 100hp Starflite 2 Stroke outboard and have wanted to do the prop shaft seals as I notice the gear oil was ever so slightly milky when I drained it. I changed all the top end seals no sweat, but the prop shaft bearing housing has completely bonded to the gearbox casing! I've tried penetrating sprays, heat, Slide hammering and reverse pressing it out, but she's not going anywhere! Therefore your method may be my only saving grace!!! I have just been paranoid about starting, just in case:- I experience a similar issue with the seal not coming out, - I push the old inner seal in too far (wasn't sure if there was a lip in the housing to prevent this)- I damaged the prop shaft or bearing housing!What I may do is pressure test the gear case first and see if it holds pressure after doing to top seals, if not I may have to take the plunge and give it a go...Your time and effort is really appreciated mate, keep up the awesome work!😉

Great video, this can be done on outdrives as well. Thanks for taking the time to make this. Good to know that there are other "hacks" out there besides myself..... Beer looks good....

Always creative in everything I learn from you👍👏👏👌

Oring and seal trick was worth the watching. Great video

Great trick, my 50 2 stroke 1985 Yamaha needs this. Thankyou

Great video for the prop shaft seals. Really helps when you have no access for the tools needed to remove the bearing carrier.

Thanks for the tip on the seal Springs. Will be ordering some first them Monday morning. plus double lip seals are always the best way to go. you should get any bad comments on that. You have to do the same thing on high performance cars when idiots decide to give the car too much horsepower cam seals get too hot and that was on an Audi R8. that's what being a mechanic is all about experience. have a beer on me for that idea 💡.

This guy is brilliant and a great tutor

Good video's . Not everything is text book . This is hands on knowledge Salute

Interesting to hear about using engineering quality oil seals .. I have done exactly the same and got the same advice from my supplier. There are some issues in obtaining exactly the right size, but I've found there are many available, that are more than suitable.

Some great stuff on a sometimes tricky part to replace. Thx guys.

I did your technique, on a 100hp Yamaha “2000”, a couple tips, a cheap set of dental picks let me pull the o rings and a bunch of the rubber out, it also let me find the holes that were already in the metal core, I actually just used a tiny screw driver to break the metal core on either side of the hole, and the ring came right out. Then while spinning the shaft with a socket on a drill I polished the shaft with sandpaper and I used the plastic pipe I had to set the new seals in, wrapped with sandpaper and smoothed out the inside of the casing!

Great video and well put!

Thank you for your excellent tutorials

Thank you for making this video, I understand why you may have had a little.... reservations about making it but man, it was very helpful as my wife and I are in some very isolated islands and I am so far from a workshop! Cheers man
