This video is about rebuilding and cleaning a plastic carburetor off of a 1993 Evinrude 225 hp outboard. I have had this motor for years and had a lot of problems with it in the beginning. I had to learn to repair the motor my self because of the high cost of taking it to someone. I found that a lot of people that repair the motors really don't know as much as we give them credit for. I found that if I follow the service manual, I can do as good if not better than some of the service personnel. One of the reasons is because I can take my time. I am not being pushed to the next job. I check and set each part to the factory spec. I did have the carburetors rebuilt professionally and when I got it back It would idle and that is all. I am not saying anything bad about service repair people. There are a lot of very good people out there. It is hard to get a appointment with them. You can get in to see your doctor faster than get you out board fixed. I am posting this video just let everyone see how much work it takes just to rebuild just one carburetor. My outboard has six of them!
Best OMC carb rebuild video on UA-cam.
Good work
Excellent video! Very detailed and exacting. Your methods are solid and are equal to my OCD ways, which says a lot! Thank you for the great video!
Just wanted to say thanks for the extremely helpful video!
Happy to help.
At 8;08 you do not ever want to take that ball out, that is a manufacturing port that is either used for molding or machining purposes. In fact it is best to use something to seal that ball up better as they start to leak frequently, I myself cover that ball with Motoseal or Epoxy.
Also alcohol is hard on many rubbers so it is best to use aerosol carb cleaner and compressed air but when using a compressor you must be careful too.
1989 Evinrude 120 V4 Pulled it out of the Barn Yesterday to go Spring salmon fishing and it fired up and ran, but no power, couldn't get on top of it. So I trolled all day with my trolling motor, couldn't let a good day go to waste, even though I didn't catch anything. Also noticed a drop of fuel was leaking from behind, above the lower unit cowling? So in a panic without ever working on this beast, I was hoping a kind individual that had plastic carbs would be generous enough to share their knowledge. Bingo! I found you. Like yourself, I'm tired of taking it to a shop and waiting for weeks, if not more than a month to get my boat back, not to mention the cost. I would think this job of replacing 4 carb kits at the shops would run $500+?
I've used your help for my trolling motor replacing the carbs, thought this bigger motor would be harder, but is't easier. So waiting for 3 new carb kits, had on already, same parts number you used and i'll then I;ll inspect for leaks and hose line fittings to make sure they're secure and then cross my fingers and drop her in the water this weekend for another shot at it. With out you tube I'm an idiot. With You tube I'm a genius! Thank you so much for you patience and step by step instructions. I'll support your channel the best i can. V/R
Thanks for watching I am happy to help. Let me know how it runs.
Back to the trouble shooting drawing board. 1.starts great. 2. idles great. 3. runs, but still no top end speed, its like running at 80%.
New fuel lines and filters last summer. stored under cover all year here in the NW. (got 62 inches of rain since last Oct. 1, yep you heard it right 5 feet.)
bought new oil water separator fuel filter. use only non ethanol. the inline filter is clear as day, can't see any debris.
Changed all 4 spark plug wires and the Coil test is between speck 260.
It's got to be a fuel issue, not getting enough. spoke to a boat shop guy, said the "jets" might be plugged. Huh? I said. I just changed the carb kit.
So.... I'm tearing back into the carbs, maybe something was not installed right when I did the job. All I know is I'm not taking it to a shop, unless I can absolutely help. I'll check for water in the system too.
I'm on a mission!
I enjoyed watching your video and thank you for spending the time and sharing your knowledge
My pleasure! Thank You for commenting.
Good advice, great video technique, fantastic tutorial. I'll nominate you for an Oscar !
Thanks for you kind words. Thanks for watching and Stay Safe.
Nice video I have to do same thing with my Johnson 200. Johnson and evinrude are the same. The parts are interchangeable for the ones that didn't know that. I will have to rebuild the carbs myself cause none of the marines near me have open appointments 🤷♂️
I like to rebuild my carbs because I can take my time and make sure everything is set right to the book. Not everybody will always do that. I have had professional rebuild my carbs years ago and the float was so far off when the boat would start to raise the bow a little the engine would shut off. Then on the other hand if it is not right you have to take the blame. Stay Safe.
Excellent video! As a new subscriber, I give you a big thumbs up. You are an excellent mechanic. Bud from Powder Springs Ga.
Thank you for the kind words an keep watching and Stay Safe!!
Thank you for the video, really helped save time
Happy to help. Stay safe.
Great video
One thing I would change the reason your carburetors are sticky is the ethanol in the gas. Best to use carburetor cleaner.
Great job of narration
Thanks for the info! Thanks for commenting.
Another GREAT video! Thank you!
Thanks for the comment. Stay Safe.
Think you
New subscriber here! Outstanding video! I've got a 200 ocean pro and I do believe the carbs are the same. This is gonna help help out a lot. Thanks for doing these videos.
Thanks for watching and subscribing Stay Safe!!
great video. works for 2000 johnson as well
The motor I am working on is a 1993 Evinrude Ocean Pro. I don't know for sure on the 2000 model.
@@OmFishing rebuild finish today. cranked on the first try and ran smoothly. the plastic washer under the needle seat is not need on my. the is a built in flange.
Good video.
Thankyou. Stay Safe.
Let’s hear it RUN
When the weather warms up some I will do that. Thanks for watching and commenting.
These carbs are a big problem on these looper motors
Only if you don’t follow torque values. They will warp and start leaking fuel if you overtight the bolts.
Other than that they are of excelent quality and corrosion resistent
What is the pressure for the pump to go into the carburettors? If you want to put a electronic fuel pump on it
I have found that motors with a carburetor are low pressure pump 3-5 pounds. I think the high pressure pumps are for fuel injection. I would check the test pressure for your motor.
Brother Nm metric torque which stands for Newton meters I use to torque all the bolts on the machines at work . Volvo and caterpillar, tower cranes and crawler cranes Take care and stay safe, by the way very nice video.
Thanks brother Harvey I can count on you to keep me straight.
Your welcome Brother, keep up the good work. Stay safe brother
I thought the needle valve seat didn’t require a gasket on a plastic carb. Why did you use one?
Excellent tutorial! Curious what symptom led you to rebuild the carbs or did you just rebuild to ensure they were optimal?
The first time I rebuild the carbs was lack of power and hard start. Now I rebuild in the spring just to be sure. Carbs and spark plugs. I will change spark plugs two to three times a season. The savings in fuel pay for the plugs.
@@OmFishing Changing your plugs that often is beyond ridiculous as they do not go bad or wear out that fast, when they wear you can see metal erosion on the spark areas. If you are changing them because they are fouling you should re jet for better mixtures.
Awesome video brother! Do you have any idea how the bowl is vented on these carbs? I have one that no matter how much I clean it, no matter how float is adjusted, it bubbles fuel up the main tube into the venturi at idle. None of the other carbs do it, so I suspect a venting issue. Thanks again for an excellent resource in this video!!!
I am not sure on this one!
Look at the video at 3:46 seconds, see that L shaped pipe with the hole in it, that is the vent tube. On some carbs there is a L shaped fitting that plugs into the carb and it faces directly at the mounting flange but has some space between the two pieces.
Nice video!
Did you have to take the lower cowling apart to get the bottom carbs off? I'm getting ready to do the carbs on my Johnson 175 Ocean Pro. Thanks!
No I did not take the lower cowling off. It would have been easier to get to but I just worked around it. I was not a bad job. Stay Well.
Like your videos. How do I get check valves our of 96 200 johnson.have it apart
When I changed mine I took the intake manifold off and pushed them out from the back. They had a o-ring on them that seal them.
Do you know where I can get part number for carb kit for 2003 Johnson 90 saw your video on the rebuild. Thanks for any help
I buy most of my parts from boat net. I did look at the 2003 90hp Johnson and a few models have the carburetor repair kit. Part Number that I found was 0438996 Stay Safe!!
Om Fishing Thanks I really appreciate your help. Really enjoy watching your videos helpful.
High speed fuel orphace oh yeahh
Thanks for watching and commenting. Hope this helps. Stay Safe.
Do you know where to get the bowls for these when the warp? Local shops around here say they're obsolete.
I don't have any around. I have seen them on Ebay but you never know what you are getting. That is the problem with some of these motors part are hard to get.
I know it. Same thing with my 82 f150. Used to be cheaper parts now they're just obsolete. Figures. I've got them double gaskets now. Its working. One guy told me to try and boil them and to place a brick on top of them. Guess we'll see when that time comes. Thanks for the reply though man.
Hello I’m looking for a rebuild kit for my 1998 evinrude 175 not sure which one to get
I like to buy OEM parts whenever I can get them. I looked at boatnet.com and found the rebuild kit you are looking for it was part number 0438996 the cost is $31.00. I have ordered part from them before and sometimes shipping takes two weeks and other time two days. You might want to call them if you need it fast. PS don't pay for fast shipping it does not help.
@@OmFishing thank you I really appreciate it
@@OmFishing is the kit for all 6 or do I need to order two I couldn’t tell thank you so much
@@jonathanravelo2263 The kit is each. When I rebuilded mine I ordered six.
@@jonathanravelo2263 Happy to help.
Plastic carbs... how cheap can they get. I got 6 to rebuild... have new float bowls for them too. My are warped and weeping. I went all out and bought Chinese float bowls to go no Mexican carburetors... Even Weed Eaters have an Aluminum Carb.
I know what can I say. Be sure and let me know how the Chinese and Mexican"s get along.
@@OmFishing will do... hopefully they will... if not I have a surface plate and know how to shave.... a machinest term not used much since the 1950's. Im still discussesed in how cheap America manufacturers got during this time.
It was a stupid cost cutting idea to go with plastic carbs. They also should have went with 3 - two barrel aluminum carbs like Yamaha did.
Well so far the Chinese float bowls on the Mexican carbs are working fine... no leaks yet...
May I ask does this help with a stuck reed issue? Im about to rebuild my Evinrude 200 and one has a stuck/faulty reed? In particular this is my issue, ran it several times but want to get it running right. Thank you for any consideration.
ua-cam.com/video/03GSSl0hJhU/v-deo.html
I think if the reed is sticking because of oil rich mixture it would clean it up. If it is another issue I don't think it will help.
