Thanks for the great video on the carburetor. I have a '66 9.8 that runs great now after I changed the impeller. If I ever need to clean the carburetor I'll refer to this video as it's very well detailed. Cheers
Sigh. I am so close to getting this engine working again... Many interruptions and delays later... As I said, the carburetor is cleaned/rebuilt and re-installed. I finally got back to this project, with new fuel tank/line and fresh gas/mix. Also installed new spark plugs. I cannot get the engine to fire/start. Fuel is definitely getting into the carburetor. Is there perhaps some carburetor setting/adjustment I can or need to do? I am baffled, as it would start and at least idle prior to the cleaning.
@@adamlerner8425 Both coils tested bad. I was able to find a couple new ones after a bit of searching. I also got new points/contacts, since the ones in there were at least ten years old. I'm trying to find exact information on how the point get set. I know the gap is twenty thousandths, but I need to know if that gap is set with throttle closed/idle or open...
Hello just picked up this same motor. And I was wondering if you can do a detailed walk around of the motor specially the top side and back. I have the catalogs part and I noticed a few things that might not belong to this motor of mine can you pls help me with a motor video. THANKS A MILLION
Is it ever the fuel pump? I’m just looking at mine and wondering. Just bought a 1968 9.8hp that will run on spray and has 105 psi in both cylinders. Does gas from primer bulb flowing thru the punk rule it out completely?
If it runs with spray I would remove the gas line from the carb and see if it's pumping fuel while you keep it running with spray. That will rule out a bad pump. Then you will have to check the carb if the pump is working.
Have the merc 110 9.8 - 1969 and it won’t idle! Carb cleaned, new fuel mixture, runs well with throttle open. Fuel bulb stays hard, float and filter free of dirt, tried idle adjustment and still no luck. It seems to pick up rpms when slowly backing off throttle from ‘start’ position to ‘shifting range’. Not sure what to try next.
Hi just got my hand on a 110 like this one . but I don't know the year can you tell me year so can get a manual to start making repairs. any help is greatly appreciated.
Tenho um motor igual a esse, ele funciona bem, com pouca aceleração ele vai bem, quando acelera mais ele treme todo parece que não tem uma boa queima, e quando acelero totalmente ele volta a ficar bom, o que pode ser o problema?
Just found this video... I have a 1970 9.8 that I thought was good to go but I took it to the local lake this AM and it would only run at partial throttle when under a load/in gear. Every time I tried to open the throttle much past the start setting it bogged and quit, if in gear. Runs at all throttle settings in neutral. Do you know if the 1970 has the same carburetor as the 1967 in your video?
@@LonnieJohnson1 Looks like mine is the same as your friends. Did you have to replace any gaskets or seals when you did the work on your friend's carburetor? Just want to know if I need to order part before pulling the carb. off for clean out... Thanks.
I have a 1972 model with a KB11A carb. I just took it to the river this weekend and am having same issue as you. It will idle and throttle up in neutral all day. It will even jog in forward gear with a little throttle, but it eventually dies if you throttle too much. Have you found a solution?
Can u make a video on how to adjust the carb on one of these old 9.8's? Mine has a speed issue lol cant get over 10mph full throttle and I've only got a 12ft v hull aluminum boat

I found a carb repair kit for my KB11A carburetor, so my small engine repairman has it right now. Will let you know if it resolves the issue. My small engine repairman also wanted the fuel pump repair kit, but I’ve been unable to find one. These parts for these old Mercury motors are disappearing.
Eny one got a link 127. Bucks a peace on the coils it had spark as i boat it i barley tutched the ciols and they totally broke before i started to mes with the coils it almost started i just cant finde parts if i do there crazy expensive
Vai a Mercury web citare e digita il numero del tuo modello. www.boats.net/catalog/mercury?gclid=Cj0KCQjwxb2XBhDBARIsAOjDZ35buuqQtDOZVTN4sgSPYrjlvHg9PQ62hkFGX9YTBL7JomfOXB1GfAIaAgVXEALw_wcB
Dont laugh... I just bought a boat with a similar motor...Could not for my life find how to open the top case. You showed me in the first 30 seconds of your video.....

Great help. I just got a family heirloom mid 60s that looks just like this, and this was a big help getting it open and knowing what is going on.
Cool!
Very similar carb set up on a 1967 Merc 6HP outboard as well! Thanks for the walk through! It was super helpful!
Thank you for making this video this is my first motor I’m messing around with so hopefully I can succeed In cleaning the carb
Your welcome

Your welcome and thanks!
What size impeller inner diameter did you end up buying? I have 1968 and not sure which I need .438” vs .456” driveshaft diameter
The 69s had the Nicest Decals of all the Mercury Outboards. They just looked better with Red
I agree
Thank you for the video. Aside from a slightly dirty screen what issue did you find while cleaning the carb?
It was full of dirt.
Very helpful!! Great job on video, no bs...thank you good sir.
Thanks, and you're welcome
A GREAT to the point video...thank you!
Thanks and your welcome.
Are these ever going to be collectable? Cool oitboards

Stop running it in the toilet.

Sounds like it's not getting gas. When something is running out of gas it normally speeds up before it dies.
Very good directions
Thanks
Where did you buy a new carb kit for this carb?
Go to (boats net) and select Mercury then put in your model#. Let me know if this helps.
Yes, it worked, thank you!
Cool!
good video what about the fuel pump?
Just a primer bulb, didn't see a fuel pump.

Also, reading between your fingers in the video, that is a Tillotson model KB-8A carburetor. I'm still trying to find a rebuild/gasket kit.

How do I remove the fuel lines? They’re crimped lines to blocky brass threaded adapters for every connection
I would have to see a picture of it. I will try to find a picture. Is it the same motor and year?
@@LonnieJohnson1 I think I see that you have to disconnect one end first and then rotate the whole hose assembly to unthread it front another port.
Back in the day everything was made to last. Now days everything is made to fail. It's all about the money anymore.
Where can I find parts for this motor I'm need a fuel pump
Whats your model #?
Eny one got a link 127. Bucks a peace on the coils it had spark as i boat it i barley tutched the ciols and they totally broke before i started to mes with the coils it almost started i just cant finde parts if i do there crazy expensive
The only bad thing about owning a boat is that marine parts are not cheap
I have this exact model, just priced a water pump for $150
Marine prices on parts are a joke!
Does that mtr have a magneto
From the spec's it look's like it does.
What was wrong w the carburetor?
It had to be the filter clogging up.
@@LonnieJohnson1 It didn't seem that dirty to me but glad it worked!
Your right it wasn't that bad but it wouldn't stay running. Did have a very small amount of dirt, but runs good now.
I cant when pill the rope on my, it just stops. What can be wrong?
Make sure you are using a gas oil mix or it will freeze your piston to the cylinder wall.
Wich ratio of gas- oil ? 50:1 or 40:1 ?
50:1
Thank you mr !
Your welcome, glad to help.
What carb is that?
It's a very old carb that is hard to find if you can find one.
Tillotson KB-8A carburetor.
Ciao anche io ho un Mercury 35 uguale al tuo sai dirmi dove posso trovare i ricambi

Doesn't look like a '67. Covers and decals look like a '69. Maybe it's mixed bag.
I have to check the #'s
My '67 9.8 Kiekhaefer has an aluminum choke plate.
Maybe that's another indication that this motor it's a 69
My 1968 also has a full metal choke plate. Similar in design but very different in construction
My -66 also...

The covers say it's a '69.
Where do you see a 69?
@@LonnieJohnson1 The red bands on the sides, the 'Merc 110' above that and the '9.8 HP' font below.
