I want to rebuild all of the carbs on my outboards (12 total) but I have never done it. Does anyone know how hard it is to remove the carburators on my outboards? It looks like they can all be removed at one time like a block.
Should I attempt the rebuild myself? Any idea what a shop would charge to rebuild all 12 of them? The Sierra rebuild kits are significantly less money than the Evinrude OEM kits, is there a difference in quality between the kits?
I know I've got problems with one carb on each engine and none of them have ever been rebuilt. The engines have 785 hours on them, should I rebuild them all or just the two that are a problem?
1) What makes you think they need rebuilding? You know, if you have ethanol fuel, it may be that your feul hoses are NOT SAE alcohol-rated hoses and perhaps your fuel hoses from the VRO to the manifold and the to each carb are breaking down inside ...
2) Carb rebuilds are VERY easy to do yourself PROVIDED you have the OEM factory service manual and not a worthless manual like a Cylmer or Seloc. The OEM manual gives you step-by-step instructions specific to YOUR model and year.
When re-installing, you should have a sync&link done, and you need a special piston stop tool for that. Or reinstall yourself and have your dealer check your work and then do this.
You will also need tools like a torque wrench in inch-pounds and possibly foot-pounds.
3) The carbs are mounted on the intake manifolds. Usually on OMC V6s the top 4 are one casting and the bottom 2 are another.
... very surprised if those kits were > $20 each, but I have noticed that parts for older models are getting pricier. In regards to 'how much' a dealer will charge, I'd bet it would be 1-2 hours to remove, a 'stock' price per carb (but could be 3-6 hours total), then 2-3 hours to reassemble, adjust, and test.
Get some prices, but I tell ya ... you can do this yourself and you'll learn a lot about YOUR motor but you really need the OMC factory service manual to do it right. There is a wealth of info in these manuals. Feel free to PM me, I could copy and send you the details on a '97 V6 teardown and carb rebuild, so you could see what you're in for.

Thanks for the info, I do have a factory service manual which is why I was thinking of doing it myself. I know that I don't have any ethanol in my tank because I get fuel from my marina and they told me they don't buy ethanol fuel. Of course I guess it's possible that they got some and didn't know it.
The top carb on my starboard engine has fuel running out of it that runs down the front of the other carbs and then into my engine cowling and into the water. I discovered it when I kept seeing the telltale rainbow when idleing at the dock. The port engine has a middle carb that the doesn't seem to be working at all, when I squirted fogging oil into it this fall it would run right back out. The other carbs sucked up the oil just fine and you could hear a change in the engine.
I've got torque wrenches but I don't know how to do a sync&link. I found the Sierra brand rebuild kits for $12.95 each but the OEM Evinrude are $24.95 each. That is why I was wondering if there was a difference in quality between the two.
I'd start by doing just one. Sounds like a float/needle and seat problem. Or even a leaky bowl drain plug. Those plastic carbs are not always real flat one the mating surfaces either. don't fix it if it ain't broke...
Re building them carbs isn't rockit science if its just for leaking pr flooding all you do is replace the needle and seat ......BUT if its a performance issue you are not Qualified and I doubt you have access to a ultra sonic cleaner. I would recommend sending them out or having them done by a knowledgeable person who is REAL Fillmore with throes carbs. The book doesn't describe some of the critical issues that need done .If you do remove them remove the Throttle plates with the plastic bodies dont seperate till you have them on the bench ,replace the same way.Make sure your floats are leval with the carb turned upside down ....Good luck

I just did my carbs on my 115. It was pretty easy. Since I had them off I went ahead and put on a new fuel pump, and all new fuel lines. Make sure the floats are level.
I'm about to do mine. I bought the Sierra kits @ less than $10 each. Looks very easy. According to the manual, the carb bodies remove separately, leaving the butterfly assy's on the engine. The only thing I was warned about is that they should not be soaked in solvent due to the fact that they are made of plastic. If you botch, bungle, or ruin a few, don't worry. I bought a complete used set for my engine on Ebay for $50. I figure I will rebuild and install those next time, for less down time. Parts are embarrassingly cheap for these engines.
Doing the carbs are no problem. I can set you up with the OEM BRP kits at a great deal. PM me if you would like a quote with shipping. I can get them out to you on Tuesday.
I think I need to do the carbs on one of my motors, 99 johnson 225, the port engine sneezes and stalls at idle a lot, especially when cold. May be just dirt in one or more carbs but I figure while I have them off to clean I will rebuild them. I have been trying to find a source for factory service manual, anyone have a link to one?

What is that sucking sound?
There is a solvent that the plastic carbs can be soaked in safely. Had an old JOHNNY-RUDE mechanic tell me to use the EVINRUDE engine tune-up to soak them in. It's pretty pricey though, but works great and has yet to harm ANY of the plastic carbs I've soaked in it.
As far as rebuilding carbs, it's a pretty simple process, just one which takes some time. I did it on my twin 175's and no problems at all, although I was a little worried about it. Anyways, the manual is a definite must which you have. If you follow it all the way through you should be up and running in no time.
Barnacle Bill: what would the cost be for an OEM service/repair manual and carb kits for twin 175hp v6 optical 60 degree engines from 1995?
