How To Service A 4 Stoke Outboard Motor

[@bruktmoped]

You should not use anti seize on new spark plugs. Most major brands like NGK, Denso and Champion advise against it. For instance, NGK spark plugs feature what is known as trivalent plating. This silver- or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without the use of anti-seize. NGK tech support has received a number of tech calls from installers who have over-tightened spark plugs because of the use of anti-seize. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage. If you insist on using anti seize, at least torque them with 20% less torque than specified to avoid ruining your threads :)

You are spot on!!

[@christopherlane4583]

Great video as always probably the best in the business with outboard motors

[@jeffmckinsey8769]

And now it's ready for another 1000 hours,I have that same motor I love it

[@kevsrods]

Great informational video, but I do suggest, after oil filter change, turn the engine over a few times without it firing up, to allow oil to get around the engine. Then & only then start it up.

[@travis.stevens]

Ha! I knew you'd join the Dark Side one day! Great video as always. One of the best outboard channels on KZbin!

[@craftsmandude8916]

What do you mean dark side

I'm looking into buying a used boat with a F70 yamaha 4 stroke. Just wanted to see what I'm getting myself into. Thanks for the heads up. Awesome video!

[@joemartin6439]

Thank you for the best video on servicing my Yamha 50 on my pontoon boat in Canada

[@sneakyblackdog]

I've viewed a few of your videos, very well done, keep them coming

[@trngpl]

Love your videos! I'm learning lots of important info from all your videos!! Thank you

[@lucabuca5367]

Love your videos! I'm learning lots of important info from all your videos!! Thank you and keep it up!

[@EnlightenedCerebrum]

Great video. Lower unit oil looks milky you might have some water mixture in there. Inspect gaskets.

[@bluethunder1951]

After watching so many of these videos on servicing outboard motors, it recommended “not” to use anti seize grease that has other metal compounds in them like copper, they will react with salt and destroy the motor housing that is made of aluminum. Mose just recommend to use a synthetic grease. Other then that this was a great video.

[@timmartin8191]

Thanks for another awesome video. First class instruction!

[@swn69]

Excellent tutorial. I'm going to do this myself next time.

[@Jackson-lz5uv]

How did it go

[@jeffcoleman9933]

Always start a spark plug by hand first. This will eliminate stripping the threads on the block!

[@hallobyebye699]

How do you perform a so called Starting a spark plug by hand ??

[@coreyholmes2229]

Hallo Byebye he means start threading the spark plug into the block by hand to avoid cross threading.

[@ivanildoalmada5458]

best video I have seem from maintenance...keep up mate

[@billearnhardt2638]

Very good instructions, thank you. Ii will be able. To. Do this. How often should this be done ??

[@stevesdaysoff2759]

Great video. is it water proof grease you use in the impeller housen and the shaft. Thanks Steve.

[@ricks2907]

Great help and good camera angles I subscribed today. Thanks 🙏

[@skandic440]

your forgot the fuel filter also.

[@mark9378]

Shoutout from down Under Australia. Great video mate. Same process for the Yamaha F40? Cheers. 🤙⚓🇦🇺

[@lamugaspearfishing5826]

Hello! Can you do a video about replaicing the internal anodes of a yamaha outboard like this? Thank you! Good job

[@rouseyanglerholics]

Hey champ, I recently got a boat with an old Yamaha 50hp 4 stroke on the back. But the model number sticker has peeled off. How can I work out what the model is?

[@johncali9]

Thanks sir i am very like your channel thank you for teaching

[@travis.stevens]

Also, what are you shooting videos on these days? The quality looks superb.

[@jeffreythomas1110]

Eric great video as always! I have a 20hp 4 stroke tohatsu 2016. Prob 50 to 75 hrs on it. I changed the oil last December but that's all I've ever done to it. How often should I consider changing filter, lower unit fluid, plugs, and impeller? My pee stream is still as good as the first day I cranked it. Thanks so much for the great info on your channel!

[@crankinbass5758]

Jeffrey Thomas definitely Change the impeller every year, consider replacing your filter every 1-3 years depending on use.

[@nintendude1988]

Don't fuck around with trying to squeeze extra life out of parts on your outboard just to save a few bucks. Manual says yearly or every 100 hours for oil and filters. I do mine every year.

[@officecarslz1789]

Good man thanks 🇧🇷

[@davidhook487]

Good stuff thank you so much! Very helpful!

[@buntychea2616]

What is that front most tube for? I just bought a 2003 f30 that runs fine, but that tube wasn't connected to anything. It runs through the fore section through the bracket. TIA!

[@truthhurts1339]

Dude, you are awesome

[@taims5165]

Never use the lower unit gaskets twice ... may cause leaking oil or water getting in

[@trangenusa]

is it alright to use Synthetic motor oil? and Synthetic gear oil?

[@davidhook261]

Great job! very helpful! Thank you very much!

[@mozolf]

I enjoy your videos. Do smaller engines have an oil filter? I have a Mercury 5.5 HP engine which I service myself. I have never changed an oil filter! oops!?

[@benmurtagh4537]

It’s generally a good idea to try and change your oil filter most times you service your engine.

[@kellylucas168]

Two stroke don’t have a oil filter

[@georgefaulkner7376]

Great video, but that oil level didn't need topping up, 1/2 way between low and high marks is perfect on 4 stroke outboards

[@yordanrodriguez42]

That's my understanding as well. 1/2 mark is the recommended.

[@Highstranger951]

My f90 manual says 1/2 way up the crosshatch is proper amount

[@harleymurphy9025]

I've been subbed for sooo long

[@kelb8334]

I have a 40 HP Yamaha. Stalls out while it’s in full speed? Remains on but has no power. You have any ideas?

[@danielcrabtree7621]

Amazing videos how did you learn how to know a engine that well was it a course or something like that

[@benmurtagh4537]

Generally you can get a coarse but if you know someone that services motors then you can look about getting an apprenticeship with them.

[@phillipmatthews8341]

Great video.

[@renecenteno5921]

Eric! What type of grease do you use for the lower unit bolts?

[@benmurtagh4537]

Generally when I’m servicing motors I’m not too picky, I usually just use anti-cease or copper grease.

[@AngryNorwegianFisherman]

i dont think copperpaste on sparkplugs is recommended anylonger

[@benjaminmaxwell8732]

One question. Where do you drain the oil from? I'm stumped.

[@Minibikebenji]

Honda Grom in the background :P yeew! haha

[@39gripen83]

The gasket on the oilfilter, are lubricated from the producer.

[@Captain-ku2rm]

Do you recommend using synthetic oil in a brand new 4-stroke 25hp motor?

[@mechanic4744]

Yes

[@jpl3622]

most mechanics will advise using dino oil for the first 200 hours to help the rings seat, then switch to synthetic. check out bobistheoilguy.com forums.

[@sionematapepe1488]

[@quyendang3234]

[@neillee3793]

Suggestion: Show adjustment process if correcting "gap" space of spark plugs - your video failed to show this procedure. Your first plug indicated not needed and you fail to show process, if needed.

[@jlo13800]

feed the oil into the manifold with a vro pump and take it down range and blast to pieces to kill it, 4 strokes make good target practice though for my rifle, they are fun to destroy as i hate them, hehe
