How much would it cost at an honest dealer to rebuild the four carburetors [on a 2002 Yamaha 60-HP four-cycle motor]? I've been quoted prices from $500 to $900.

That dealer is NOT honest. $50 a carb should be max.

That dealer is right on and maybe on the low side! The carb kits are well over $50 each x 4 for that motor and lots of pricey fuel lines that probably will need replacing. The "j" ones that are over $40 at cost that will most likely need replacing when removed. Very easy to spend $400+ on fuel lines and carb kits before you even get to the labor. A very good mechanic could spend eight hours plus to do the entire job right. $200 or $50 a carb for that job would be a hack with a can of berryman's telling you he "rebuilt" the carbs.

Well my Hacked carbs work just fine and I have NEVER needed a carb kit...EVER. I have bought ethanol compliant needles and seats and a gasket here and there but a complete carb kit is a waste of $50. This engine is a 2002 and is probably just a little gunked up. It does not need an overhaul, just a cleaning where a can of Berryman's, some torch files, and compressed air will do a perfect job. I will put my carb job up against any $900 dealer scam any day of the week. People are being ripped off and they should be made aware of it.

Guy is getting an estimate to have his carbs rebuilt not cleaned on an engine with many preformed fuel lines that will likely need replacing. I own a year 2000 50hp version of this same Yamaha-powerhead engine, and it not only needed kits but several fuel lines as well. $200 for a complete carb rebuilding is a pipe dream from a reputable shop with qualified staff, overhead and the desire to make some sort of profit. This engine has several lines that need to be located precisely in a very small area behind the carbs and sandwiched next to the powerhead. Not only is it a bit more complicated but the preformed lines must be used.

Terry, I would pick a reputable dealership that is willing to stand behind the job. This simply isn't a $200 job, not even close. A reputable shop will thoroughly clean and install new kits in your carbs. Replace any fuel lines that are leaking or suspect. Then test your motor upon reassembly. Yamaha motors like carb kits and fuel pump diaphragms.

These four-cycle engines with low fuel flow rates seem to have frequent problems with carburetors.

Buy a service manual and do it yourself. It is not that difficult if you have the tools. If you don't have the tools buy them with the money you save. I never rebuilt any outboard motor carbs and did it with a manual and the kits. The motor would not start and after rebuilding them the motor fired up on the first crank and idled like new. It was a great feeling. The problem with taking the boat to someone is you never know who is a hack rip off bs'er regardless of what they charge.

Just some food for thought: Ethanol compliant needles, seats, and a gasket were something I thought I might need with a recent fuel delivery system problem in my 2005 Mercury 115-HP carburetor engine. As it turned out, something else was the problem, but I was quoted $8 for each of the four carburetors. That of course did not include labor. The parts are cheap, the labor is not, and in my case there was no good source for that labor within hours of the boat. Lots to think about. Henry

If you own one of these four-cycle engines with multiple carburetors and a tendency to have problems with them, it probably is a good idea to become familiar with cleaning and rebuilding them. You will save yourself a lot of money in repair bills. Although in saying that, I cannot speak with experience. I don't know how difficult removal, rebuilding, re-installation, and re-synchronization of the four carburetors might be on one of these engines. The difficulty in performing some repairs is often related to the particular design of the engine, where the components are located, how easy it is to reach them, and the need for specialized tools to work on them.

Jim carbs are carbs for the most part. I have rebuilt everything from a 5hp Briggs carb to 1150 Holly Dominators to Kawasaki ninja carbs to outboards. This is no rocket science and I never even used a manual. Lines that need to be replaced should be replaced and gaskets or parts that need to be replaced should be replaced. Going out and buying $200 worth of carb rebuild kits is stupid. Would you buy a whole new computer if your mouse went bad? Bris and others can take their engines to whatever stealership they want but I guarantee you that I and about 6 other of my friends(some CW members) would do the same quality job for a case of beer. My mechanic friend who is certified Mercruiser charges $50 a carb to rebuild, $80 more to remove them and install them. You usually do not have to synchro them if you do not mess with the butterflies, etc. Any good shade tree mechanic also owns a set of carb sticks. If you don't know what they are then you should probably just stick to getting raped by the dealer or maybe get a manual and learn how to do something for a change. Cleaning carbs is not much harder than a waterpump replacement. If I had to pay $150 everytime my carb stuck on my 9.9 or 90 Yamaha I would have about $3k in them....don't be a Lemming.

Setting a carburetor in front of some very smart folks and asking them to fix's like asking a beer connoisseur to drink non-alcoholic beer. Sometimes it just can't be done, ;-)

Then pay $800 or whatever but don't bitch about it afterwards. Once the carb is off it takes 5-10 mins to clean it, maybe less if evident what the problem was.

Not me. I got injectors. They are only $25/ to clean. In 20 previous years of carb's engines, never had a need to re-build. Just liberal use of Ring Free and Sea Foam.

I was quoted $300 to remove, clean, rebuild, 3 carbs on a Yamaha, seemed fair.

I do not know what a "carb stick" is but I do have a service manual. And it helps a lot. I have saved a lot of money doing maintenance and repairs with it. So: What is a "carb stick"? Is it a tool used to set the float level? I don't recall any other tool I used to rebuild my Evinrude carbs that looked like a "stick."

Once I had the carbs off it took a lot more that 5-10 minutes, but that is because I work like an operating room surgeon. If you haven't done it before having the right tools, paying attention to detail and not rushing it is the key. Study the carbs carefully at each stage of the rebuild before disassembly and even take notes in case the manual leaves out a detail (they often do). Label parts as you remove them and diagram where they go. Have a clean table, compressed air, and all the tools laid out and clean and the manual opened up, have some Mercury Power tune or an equivalent handy. Spray and blow. The problem in my carbs was that the motor sat for a long time and the fuel/oil mixture in the carbs dried up leaving the oil residue gunk to clog the passages or whatever. The gunk was clearly visible upon disassembly. I probably didn't need to replace all the parts in the kit but due to inexperience I didn't now which ones were bad so I replaced everything with the new parts in the kit. Like I said it started right up after I put it back together.

I am a paper pusher with no technical training and if I can do it anyone can. Unless you have no curiosity and are not inclined to follow instructions and pay attention to details. Basically rebuilding a carb is like working on a 3-D puzzle. If you are inexperienced in this type of thing and are not inclined to work in the way I mentioned above then you probably should take it to a "stealership." Basically one should be "anal" and tend to do everything in an "overkill" manner.

Tohsgib is experienced and knows what he is doing and has given me very helpful information in the past, but he forgets how intimidating a big outboard motor looks under the cowling to a person who does not have experience with them. That is why a service manual is essential, I think. Unless you are an expert.

I am as handy as the next guy and have done some minor repairs to outboards over the years. The carbs (4) on our 2003 90hp 4s Mercury were seriously fouled by ethanol degrading the engines fuel line. My Mercury dealer is certified in every area of Mercury installation and repair. My mechanic holds close to every certification obtainable from Mercury Marine. Where I'm going with this is both the dealer and mechanic said I could rebuild the carbs myself but it was not an easy 1 2 3 kinda thing and adjusting them properly could be tricky. I let them remove, rebuild, reinstall and tune the fuel delivery system including new hoses, carb kits/gaskets, and add a stainless steel gasoline filter water seperator with Racor filter. Cost? right at a thousand dollars with tax.
Nick, not everyone is as comfortable tearing into an engine as you seem to be and I am not fond of your attitude of talking down to those of us who aren't. I've met you in person and you seem to be a pretty nice guy but at times your screen name is well justified. If everyone was as talented as you appear to be there would be no need for dealers or repair facilities.

I am pretty sure I have rebuilt and cleaned more carbs that Nick has. I also happen to own this particular motor and hell I even think I know what a carb stick is. Anyhoo this particular one ain't a $200/ case of beer job, no way no how. No need for the original poster here to get mislead and misinformed. Buying four carb kits isn't stupid it is just a desire to want to do the job right the first time and often is easier than just buying seperate gaskets and odd bits as Nick suggests. Pull up a diagram of the fuel lines on this one fellows. Any suspect lines need to be replaced and the must be replaced with the oem stuff as they have a very precise locating sequence. The fuel lines are $$$.

I'll steal one of JB's lines ..he who works on an engine without a manual has a fool for a mechanic.

What do new carbs cost?

New carbs = big bucks and much of the labor involved in the rebuild is the removal and replacement.

I do most if not all my repairs. Can understand why many outboard owners prefer to have repairs done by a pro. What may seem simple to those mechanically inclined and a bit of experience can be overwhelming to many who lack it.

Thanks for all the replys. I've never had an engine like this before. I did have the engine done by a certified Yamaha mechanic, but will invest in a service manual.

Sorry if I was condescending but when a legit carb cleaning for a resonable price is automatically assumed to be a "hack job" I wanted to make it completely clear how easy it is to rebuild a carb. As Blackduck and others have posted, $800 is WAAYY too much to clean 4 carbs.

Yes a carb stick is a synchronizer to set up all 3 or 4 carbs the same. Not necessary but you should notice it to be much smoother running.
