Vložit
- čas přidán 7. 09. 2019
- In this video we show you how to remove, disassemble and clean / rebuild your carburetor on a 1990 Mercury / Mariner 15hp outboard motor. We detail a lot of steps particularly how to remove and reassemble the choke enrichment valve.
This is a true do it yourself video!
As an added bonus we will also share a word of encouragement with you about what the Lord has done for you and I.
Thank you for this video and sharing the Word of God. I have this exact carburetor on my 9.9 HP Mercury. I came searching for a how to video and was pleasantly surprised to find a fellow believer. God Bless.
You are welcome! Thank you for the kind comment.
Thanks for the very helpful video!
I've worked on Johnson & Tohatsu carbs before, but when I opened up my Mariner 15 and realized the carb wasn't just going to lift out after removing the flange bolts, I went in the house, washed my hands and hit the keyboard. Thankfully I found your video! Without it, I surely would have ended up breaking some plastic part of the enrichment assembly.
To other readers, a general word of advice when cleaning carbs - wear eye protection! When you blast carb cleaner through those little passages and jets, you can never be sure where it's going to come out!!
That advice about leaving the carb a little loose getting the pull to prime mechanism back in is solid gold. I fought it for awhile.Thank you buddy
Hey thanks for the video I just purchased the Mercury 9.9 was starting fine from the beginning then all of a sudden it wouldn't start so I was checking on videos on CZcams and came across yours followed all your steps it was basically the same carburetor I took everything off cleaned it and boom it started thank you so much God bless and also thanks for the encouraging word of God very good you don't see many people doing that on CZcams thank you God blessings
You helped me out so much I am just now fixing my grandpas boat he left to me he passed away in 2018 so I’m freshening everything up and hope I can run it
a warm greeting from Italy brother, beautiful what you did, you put an evangelistic message in this video wow. God bless you and keep saving souls. thank you
Wow, thank you for the word of encouragment.
Very good informative information. And I would like to echo what Ken said about “preacher mechanic” LOL. Great way to spread the gospel of Christ. God bless!
Great video. You're the only person that mentioned what operates the diaphragm on the fuel pump. When removing that small hose at the bottom of the carb I noticed a hole in it. That was likely the cause of the engine only starting with starting fluid.... no working fuel pump! So, I'm waiting for a carb rebuild kit that wasn't even needed.... especially since the carb chambers and ports were all very clean when inspecting. I wish I saw this video before I tore it apart!
Good video, I was not expecting the sermon, but you have every right to believe in anything you want. One small bit of advice. Never do this on a table with grass or chippings under it, or you may drop small parts and lose them into a black hole. Also you had the chance to clean the fuel filter. Thank you and may your God go with you. P.S. Don't forget to donate any bits you have left over after a reassembly and install to a local charity.
Thank you for help!!! Are you amazing 🇧🇷🇧🇷🇧🇷
God bless you mate from Australia 👍
So refreshing during a DIY video to be reminded of what really matters in life. This world offers no hope in the end. Sure you will find stuff that entertains but it will all pass. We will face death at the end of this life so where will you be? We are not a mistake. Don't let people say that we came from nothing. Nothing breeds nothing. There is a God and He loves you... don't reject Him.
Thanks for the nice reply
Merci ! thanks for sharing with honesty and simplicity! May you stay connected to god!
Thank you! You too!
Love the video and message! Going to try my first carb.
Great video , thanks very much!!👍🏻👍🏻
Your video is great. You should go by the" Preacher Mechanic" lol
Love the invitation. John 3;16 Amen
Great job on the video and it was very helpful. Can't say I agree with a single claim you make about God or Jesus, but I fully respect your right to make those claims if you really believe them. And I do think you make those claims in the spirit of kindness and concern. And again; great video.
The Laws are made by God. Your feelings don't matter lol
Thank you for the good word sir.
I need mine rebuilded. Praise the Lord!
I wish there was a way for me to see where the linkage that's removed actual goes at the other end. Does it just sit there freely or is it attached to so.ething I can't twll?
I have the same motor but my enrichment valve doesn’t go down at all it’s like it’s stuck do you know how I can fix
very usable .. thank you, god bless.
Well done..nice video...thank you
Like the shirt and informative video brother. 👍
Very informative. Thanks.
Amen Brother, God Bless
Amen
That linkage you removed in the start, what is it?
Thank you 😊
What does that first link you pull off attach to?
Great video and message of the Gospel. Thank you.
Glad you enjoyed it
I’m having some trouble with the pull to prime knob. To get it to rotate I have to push it in. Any thoughts?
Can't get the choke knob lined up please help...same exact motor 6hp model
I have 15 hp mercury won't start, would you please send me a video of how to make it star... I do appreciate it. 🙏
Спасибо за видео.
Love the shirt
Will the fuel pump work without the spring?
Hola que número de chiclet lleva el 15 hp gracias
That was a nice video! I hope God is helping you all the time.
I wanted to ask. If you spray in to the intake while the outboard was working, with a carbon cleaner, will it be necessary to disassembly it? Will it be bad for the engine?
Spraying carbon cleaner in the intake won't do anything for the carburetor as there are small passage ways gas travels through as well as the carburetor bowl itself which only pump gas into the intake. Carbon cleaner works well under certain circumstances to fix low cylinder compression. I have a video on that on my channel.
I appreciate the effort you put in to helping others! I have the smaller 10hp version on my kids inflatable boat (inflatable bottom) but it’s just on the limit to plane with me in there together with them so a little more hp would be great. Is it possible to replace the full carburettor or just some nozzles to go from 10->15hp?
Hi Johan, Thanks for the comment. I am sorry I don't know the answer to that question.
the 6hp-15hp all had the same block of that era! the 9.9 idles a bit smoother than the 15hp , and has more low-end grunt. the only benefit of the 15hp is at the upper 5500rpm limit . trust me, not worth it.
Great video, rebuilding the carb was easy. Reinstalling the primer is very difficult! There has to be an easier way!
Your right, getting it to slid back into position takes a few tries.
I have mine what seems like it’s in position but it seems like I need to apply inward pressure to get it to rotate.
Anyone have suggestion on where I can find a carb rebuild kit for a 97 15hp 2steoke ?
Good video, is there anyway to adjust the idle on these carbs
I have a 1993 8hp Mercury; why does gas shoot out the little hole on the side of the diaphragm cover?
I am sorry I don't have an answer for you.
Float question. One side of the float has 2 dimples on it. The other side is smooth. Which side lays on the forks?
I am sorry I don't know it has been too long since I had that one apart.
Perhaps you could look at a parts diagram online and see if you can tell.
Great video!!! I wanted to ask you or anyone to see if you have a clue what could be wrong with my motor. Today I went to the swamp meet and picked up a grayish Mariner 15HP. The engine and carb looks exactly like yours. I tested it and it wouldn't start. Check and there are sparks. Traced the fuel up to the carb and it's good. Tested with started fluid inside chamber and still no start. Tested starter fluid into the carb and still no start. It acts like it wants to start but will not. Checked the fuel cut off switch and it's fine. Took carb apart and carb looks like it was recently rebuilt. Checked and air blow everything except the enrichment valve or the bottom nut, spring, ball or the passage. I put everything back and tested again. It feels like it wanted to start but still can't. I removed the gear safty lock on the pull start and attempted to start the motor in forward gear. It started if I pull the choke and leave in the forward gear. Once I switch to neutral, it'll die out. What could be the issue? I'm going to order a new carb kit and give it a good cleaning myself.
Carburetor kit sounds like a good idea particularly the needle valve rubber tip. Maybe take a look at the reed valves when you have the carb off.
can i buy one of these carburators still?
Hi i have a 9.9 2 stroke just clean and change all gasket. I put all them back now when i pump the gas im getting big leak on the side of where it say TOP. Hope you can help me. Thanks!
I'm having the same problem. Did you get it figured out
I have a 15hp Mercury longshaft for my kicker motor. I know the carb is going to be all gummed up with stale gas when I try to start it this spring. Thank you for this video.
People are free to believe any religion they want - as long as it is not taught in public schools...
Thanks for the comment. I hope the video helps you.
Traduzir em portugues para que possa enteder
Hey man, love the vid, what does the blue button on the carb do?
I believe you are talking about the enrichment valve. When you pull the "choke" type knob out the little arm comes down on the button and give the carburetor a little squirt of gas.
Oh great. I can't figure out how to remove the engine cover and you skipped that step
I can never get the damn thing to stay clean and run right.
What Armature Armature you are saying each time... It's a Lever
hello
Came for the motor fix left cause of the preaching.
at 1:13 I had to laugh,,that little pease in there,,that little pease in there can give you a time when you go to put them back in,, I’m working on my 9.9 , I think I got a 15hp carburetor on my 9.9,,it’s identical to my 15 hp merc
Hi Bob.
The 9.9 and 15 are the same motor. The jets in the carburettor on the 15 hp are slightly bigger, that’s all.
15Hp uses a WMC-49a carb (depending on year). The 15hp has a larger diameter inlet for more air and fuel.

Good video, but could have done without the Jesus-freakiness. My spirituality is grounded IN reality not in fantasy cultist-religion.
Thanks for your reply. Years ago I came to know Jesus through faith. Years later he was proven to me through science. Years after that upon receiving the power of the Holy Spirit as spoken about in the bible, I began praying over the sick and seeing them recover, seeing deaf ears receiving hearing, seeing injured arms and legs being instantly healed, casting demons out of oppressed people in the name of Jesus and seeing with my own eyes their manifestations, seeing demons talking through these oppressed people as they flee a person's body by the power of the name of Jesus. You can't tell me "it's a fantasy cultist religion" because I have seen His power in action with my own eyes and once you have seen the power of the Holy Spirit you can never go back.
Mark 16:15 And he said to them, “Go into all the world and proclaim the gospel to the whole creation. 16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. 17 And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; 18 they will pick up serpents with their hands; and if they drink any deadly poison, it will not hurt them; they will lay their hands on the sick, and they will recover.” I hope you find Jesus before it is too late, eternity is a long time!
Otherwise Useful Video
You lied, it was closer to 120 seconds of my time not 60.
Joking aside, very useful video, thanks
I like the video,even though you snuck the Jesus stuff in there,,we are all gods children,we are in heaven ,we just don’t act it,,, peace
Wrong
those reed valves are junk! that much discoloration definitely indicates backflow aka not sealing properly. good opportunity to replace with fiber reeds. makes a huge difference in starting and idle smoothness, plus cheap insurance.
Are you talking about the flapper things in the fuel pump ? if so how hard is it to replace them with fiber reeds?
@@anthonycerra5676 no. reed valves in the intake. stock ones are metal. CCMS are plastic.
Eternal hellfire we're people burn forever is false religion. To dust we are, to dust we return.
You do itnall wrong with the choke. dont remove it.
Hola usted me podrían alludar que número de chicle lleva el 15 hp Mercury americano
Was looking for a Merc carb cleaning video and instead got unsolicited preaching hidden in a "how to". First of all, preaching without asking permission or notifying in advance is rude and disrespectful of a person's existing spiritual beliefs. Second, why do you have to hide your message and sneak it in? Hiding and sneaking is pretty sketchy behavior and immediately makes a viewer suspicious of the message. All you needed to say was already said on your T-shirt. People either get it or they don't. If you feel compelled to preach and witness, do it in a forum that is suited for it. So, now you have my message.
Hi EW, Thanks for the comment. Sorry you didn't read the entire video description and you would have seen everything is disclosed there beforehand. Even the channel introduction video is very upfront. Maybe your oversight was God trying to tell you something? Hope the information about the carburetor was helpful to you. Have a blessed day.
😂
Using God's word for commercial benefit.
Hi Mark, Thanks for the comment. I suppose it would only be "commercial benefit" if I was getting paid by someone which is not the case. I hope you got you boat motor running better. Thanks
Dam.. it was a great video until the religious crap at the end.. Its 2022.. People dont believe in magic sky daddies anymore.
Keep to mechanics and leave religion out of it
Good video, just don't start with thee preaching! There's a time and place, this IS NOT it.
Excellent video minus the jesus shpeel. Thanks!
