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 :)

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

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

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

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

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!

Thanks for another awesome video. First class instruction!

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

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

Thanks for another great video.

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

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

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.

Great job! very helpful! Thank you very much!

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

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

Good man thanks 🇧🇷

Good stuff thank you so much! Very helpful!

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

I've been subbed for sooo long

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

Dude, you are awesome

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

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

awesome video

Great video.

Very profesional, thanks

I like the video thanks!

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

Nice video

your forgot the fuel filter also.

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.

Thanks dude.

I have a 64 Johnson sea horse 5.5 hp motor and have seen all the motor’s you have worked on, mines been sitting for 10+ years and wanted to know if you could do a video on a similar motor

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

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

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!

Thank you.

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?

How often do you change the internal anodes?

So good

Awesome

Thanks Bro

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

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

Awesome job Eric :D

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!

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

Honda Grom in the background :P yeew! haha

Thanks brother I'm going to Yamaha 250 in a 25 Yamaha on back of my boat

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

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

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!?

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

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

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

Relay am fully thank you for shear your video with world ,, keep it up ,, like and sub Done ..

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

i dont think copperpaste on sparkplugs is recommended anylonger

Where do you order your parts / supplies?

hey im in europe (croatia) im looking for shortshaft 8hp motor mercury do you know somone who has it?

you need to replace the seals on the lower unit

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.

We know how to operate a torque wrench.... and loosen spark plugs Thx

Lol get a 2 stroke. Replace the gear fluid and spark plugs every year and replace the impeller every 3 or so years

I really like watching yor work is there away I could contact you directly via email or messenger
