Was gonna say the same thing. Would be nice to have another video with voiceover and maybe some new owner/boater info tips.

Тhis must be done 4 times !!!

​@Wertu Fgui my manual says only twice. Why 4 times?

you were ripped off. buy used :)

@@fizwin1 ... or save your money and buy whatever you want, new or used :)

​@@fizwin1how do you know the pervious owners had access to this video and took care of it right?

do tou know of any videos to change water pump impeller

What is the consumption of liters per hour of this engine? I would like to know consumption gasoline outboard 9.9 4 stroke seanovo

Sorry, you have to wait some time cause I was replaced my 9.9 for 20efi this season.

Jay Shaw Yeah beautiful 2 strokes :D

Good power heads them yamahas, we’ve got 3 going strong well over 2000 hours, enjoy it mate 😉

Great video easy to understand and useful

Good tip wil try that thanks!

For Winter storage should I try to completely run motor out of fuel? I was told by a guy that if you do that then the internal fuel lines may dry out. if the motor is only sitting idle for 3-4 months leaving gas in the internal fuel lines wont really hurt it. Has anyone els eheard that or could comment? - thanx Harvey

@@harveypeterson9637 I starve all my marine outboard for 10 years without any problem with fuel lines.

@@SilmarilS79 Thanx Johnny!

No. That’s all.

yes, instead of flushing with water, flush with water line antifreeze instead

to avoid air bubbles.

By pulling it

3 ml. My mistake, sorry

Yea bud I added 15ml like, 🤦🏽‍♂️ this is way too much, smoked like a mofo on the first fire up ! 💨

It is factory part and comes with the new outboard

manual page 73: Gearcase lubricant recommendation: Mercury or Quicksilver Premium or High Performance Gear Lubricant ;-)

@@22gladijator manual page 73 Yes, you write correctly, this is for lubricating engine parts. There was a question about the oil that you filled in the gearbox of the engine.

Wertu Fgui think he’s just answered your question mate

I've got a 2005 15hp 4 stroke. Had same problem. The seal nearest the ball bearing on the inside of the male fuel connection was ripped, hard to see. Replaced it. Then found a hairline crack in the fuel line connector on the motor, replaced just to be on the safe side. Then found a zip tie that was not tight on the engine side fuel connector. Tighten it and decided it's not a good solution, put in a metal adjustable screw clamp, much tighter. Then I found that the quicksilver 3.2 gallon gas tank uses a circular valve to keep fuel pressure from building at the connections nearest the motor. It connects first to the tank, then hand pump, then to the motor. Now the pressure does not climb and cause dripping with the changes in heat. Also important to understand the valve on the tank cap itself. Hope that helps. Apparently the EPA made changes to the fuel lines or something that has caused problems. I saw a KZfaq video on it. Also, having the tank full helps reduce excess pressure.

@@randomdiyguy1883 thank you very much for your kindly answer.i will check one by one and try all the ways as you told.hope i ll find a solution like you.best.

yep. idle may be too high. Also mercury had some recalls on some years of the lower end gearboxes.

Rebecca Neher - it’s written in the manual.

~ 3.5l

Both, gear and engine oil

I have a 2007 Mercury 9.9 as well and this is the same.

It doesn't really matter if at start or full throttle. It's for cold starting. Once the motor is hot, it will start at idle without choke.

i have this one, its 84 pounds dry

nevermind

How its called?

read the manual page 77: remove the spark plug and add approximately 30ml of engine oil or inject a five second spray of storage seal inside of each cylinder. A little engine oil left me, so I use the first metod. engine oil or fogging spray is the same thing.

As you Said it is written in the users manual to put 30 ml oil into each cylinder but you poured 3 ml . Or did you repeat what is seen in the video 10 times for each cylinder ? In fact, It seems to me that 30 ml of engine oil might be very much for each cylinder. In other videos that I watched about winterizing, recommended amount is a spoon of engine oil four each cylinder.

Sorry, this is mistake in manual. Ofcourse, 30ml is too much. 3ml is just enough

Yes. Tohatsu factory build Mercury. But the question is still why? Do they dont fight against others anymore? Hehe i think japanese quality is good

Yeap Mariner 9.9 15 20 too

no, you don`t have to do it.

@@22gladijator Great, thank you.

Flushing plug to rinse salt water without engine on.

@@harryj1081 I guess they must make a hose fitting for that

water will show in the removed gear lube as a white creamy consistency. If that happens. you need to check for bad gasket sealing or have a professional check it.

the fuel can rinse that "film" off. Also it is better to keep the carb wet in the winter. Some disagree. Everyone has an opinion

Yes

yes, I have a 2020 9.9 and I don't use the tether cause I find it gets in the way

@@onetwothreefour111Might want to re-think that. I saw a guy get thrown out of his boat and his boat kept circling him in the water for a long time until it ran out of gas. We could only watch from the shore. No one could get near him to rescue him.

@@tomd7516 ever catch a fish while trolling and having to try and reel in a fish with an outboard strapped to your wrist.

​@Rob Cann I tie the end of the landyard to my PFD. Never an issue. I always wear one on the water, just in case.

No oil filter on 9.9

@@22gladijator you are 100% sure? Thanks for responding

@@22gladijator Are you 100% sure? Thanks for the amazing video. I used this to change my oil.

mine has one left side of engine next to the electric starter

No oil filter on our F9.9EH. There is no oil pump so the filter would be worthless :)

There's no oil filter on the 9.9 hp.

You change oil in autumn because old oil can be acidic and can promote corrosion in presence of humidity in winter storage. Old oil can contain water/fuel.

@@SilmarilS79 Yes autum is the best to have fresh, but in reality you never manage to vear it out anyway.I used a Tohatsu 25 four stroke for 12 years, on boat year round and only oil gear oil.Never fresh vater etc, it got stolen at the end. The problem arise if have to change impeller and you dont manage doing it or get proper cooling etc as i tryed no on a yamaha 8.That engine would be replased by a tohatsu 9,8 nekst year.It dont cool properly

carb models are cheaper. if you use ethanol free gas itl'll be fine if not run a stabilizer. efi is a little better at fuel usage but more expensive if it breaks cost more up front too. its really customer preference. personally i can clean a carb out on a lake. if fuel injection quits get the oars out

@@richardcranium5839 appreciate it !

carb is fine. Buy a used one if you want to save $$. Also it is nice and broken in. We bought a 2012 merc this year. Just replaced the fuel pump and did standard maint, oils, plugs, and used seafoam to clean the hell out of the fuel system and it runs like a top.

@@22gladijator Thanks, I wondered the same!
