Need help Identifying Carbs PN 433449, 199X 200 or 225 V6

[Greg_E]

I purchased an Evinrude motor that was going to the scrap yard for spare parts I needed. I stripped what I could off of it and the rest went to the scrap yard. Model number and engine cover were missing so I'm not sure if it was a 200 or 225 HP engine or even what year it was. I want to rebuild the carbs to use on my 1987 V6 225 HP but don't know what kit to order. Ive checked 1989-1994 and can't find 433449 in any parts list.

Can anyone tell me what kit fits these carbs and/or model and year of the engine?

Here's what I know:

Number stamped in the freeze plug: G2650717

Number molded on carb body: 433449 Air bleed orifices are 32 and 38
Number molded on carb bowl 333525

Engine was dark blue metallic

Trim tilt assembly was the newer style with the plastic fluid reservoir unlike the one on the 1987. I think that makes it at least a 1991 as that is the first year I found that style in the Evinrude online parts lookup.

The CR lower unit had the newer style water intake screen that screws to the outside of the casting, not the 4 round holes like the 1987 and had the one piece driveshaft like the 1987. The lower unit may have been replaced because it was originally white and had been spray can painted to match the engine, most of which had worn off.

I found an online ad for that number 433449 carb, and it said they came from a 1991 200HP. I couldn't find it in the Evinrude online parts lookup though. I think that is just the PN for the body, and not the top assembly.

Any help is appreciated.

Just measure the venturi throas as 225 carbs are right at 38 mm and 200 carbs are at 36mm ID

I'm not sure exactly where you want me to make the measurement, but I am not coming up with either of those numbers.
The diameter from the front of the carb to the start of the throat is a constant 50.25mm
The measurement at the narrowest point of the throat is 32.5mm.
There is a small 90 degree step just behind that and it measures 34.4 mm
Beyond that there is a gradual increase in diameter. At the edge it is 37.26 mm

200 throttle plates will have 2 brass screws holding the butterfly to the shaft.
225s will have 3 screws.

You must have the throttle plates to go with the carb bodies, or you will likely never get it to run right.

The throttle plates have two screws holding the butterfly. The butterfly is brass, but the two screws are stainless steel.
The throttle body bores are 38mm if that matters.

I suppose if I disassemble one of the carbs and see what size the main jet is it would also confirm they are from a 200 HP. The main fuel jet in a 200 would be smaller correct?

So if these are from a 200 HP can they be used on a 225? I understand that the air bleed orifices would need to be changed along with the main jet but the diameter of the throat would still be 2mm smaller.

I don't absolutely need to use these carbs. I bought the engine for the CR lower unit. The rest of the parts were just a bonus. I just thought that because the 1986 1987 carbs are not very good, I would use these newer ones if possible. I can always use the 1988 225 HP carbs that are on my two running engines when the time comes.

The ONLY HP MAKING difference between a 200 and a 225 is the carb assemblies. 200 hp carbs are smaller throats and two screws holding the butterfly to the shaft.
225 carbs are larger throats with three screws holding the butterfly to the shaft.
All the rest of the engine parts are the same between 200 and 225 models.

You have 200 hp carb assemblies (two shaft screws).

Here's the thing.....people try to up the HP by putting 225 black carb bodies on the smaller 200 throttle plates.
Won't work. Makes a step in the airflow thru the whole assembly.

Also they try to put bigger jets (72s for instance) in the 200 carbs....it just make WOT richer than it should be.

So, it takes alot of studying of the parts pages, paying special attention to the side plate of the black carb bodies, specifically the number of screws holding it on, the presence of round welch plugs on the sides of the throttle plates vs. small machined covers held on with four screws, the installed jet sizes, how many air bleed jets and the sizes, adjustable idle screw or not, even the proper air silencer (if you have it) can be used to help ID the carbs....

You haven't told us exactly what you have....just the black carb bodies, or the whole assy....bodies and throttle plates. What do you have?

The fuel and air feed passages from black carb bodies to throttle plates line up and in many cases they cannot be interchanged.

For example, I could not put a 1996 black carb body on a 1992 throttle plate.....air and fuel passages may not line up, may be sized wrong, etc.
You notice that the spaghetti seal from body to plate on some models has two very small donuts sticking off to the inside, and on other models it only has one small donut? Look at the pics...you will see.

From what you have said, you have pre-1996 carbs for sure.

I doubt that engine was newer than than a 1993. Something between 1991 and 1993 when the newer style trim tilt became available.

Faztbullet posted this in the other thread about the 200 Vindicator.
"The 200 hp carbs use 65D's and the 225 carbs use 72D high speed jets." That should be one more point to confirm that they are from a 200.

The air silencer was damaged so I didn't save it. It looked very similar to the one on my 1988's but I wasn't really looking at the subtle differences.

I have the complete carb assemblies, throttle bodies, reed boxes, and the intake manifold castings that the boxes bolt onto from the engine.

The throttle bodies have the round welch plugs

The air bleed orifices are listed in my first post. I could not find a model that had those exact numbers but some of the models were very close for a 1991.

The side plates on the carbs have four screws. Three are in the corners and one is further in towards the center

From what you are saying, I can build it up as a 200 HP using these parts or use the parts from one of the 1988's when one of those blows and make it a 225. (I would still need to change the main jet and air bleed orifices to accommodate the differences between the small bore 1987 and the large bore 1988, correct?)

The season is short enough here in the northeast, and the boat is 75 miles from home, so I don't want to spend a lot of time trying to use a part that wasn't intended for my application and then have to tinker with it for half the summer to make it "sorta" work.

I have determined that these carbs came from a 1992 or newer. All the 1991 carbs have two screws holding the side plate on, and these have four. 1992 was the first year for that.
The air bleed orifice in the 9 o'clock position is a 32
The air bleed orifice in the 8 o'clock position is a 38
The main jet in the stbd bottom carb (#6) is a 54D I didn't check to see if they are all the same.
I have been unable to find that exact combination in the models that I checked.
In 1993 alone they have a dizzying array of models and carb combinations
Are there any other things to check that might narrow down the possibilities? Something that will at least identify the year. It doen't even need to be on the carbs. Just something from the parts that I removed that would say that engine is from a specific year because........

Do you have a needle valve at the 10-11 o'clock position? The presence or absence of that will help pin it down further.
If you look at the Evinrude parts diagram for a 1994 E200TZARK (K is the determining factor), you will see in the carb section for "K" models part reference number 12, Needle valve.

What is the purpose of this exercise? To order the right kits? If so, if you get Sierra kits, they will have ALL the gaskets for ALL the models. There will be gaskets you don't use, for example. They will have the 5 screw, 4 screw, and 2 screw side plate gaskets all in the same kit.

One thing about the Sierra kits....the spaghetti seal is not as good as the same seal in the Evinrude kit. Also, don't glue that seal into the groove it fits into. It goes in dry.

Another thing you might consider......I see about 3-4 different Evinrude part numbers for the kits listed on the Ev pages.
It is possible that those numbers supercede UP to a new SINGLE number to cover all those carbs. Possible....I just have no way to get the supercession number chain......
435678 carb kit covers a ton of years and models......

Looking further, it seems as 439078 or 439079 are the ones you need. I believe that the only diff between the two is that one has floats (079) and the other (078) doesn't.

Look on Crowley Marine website. They are showing ONLY those two numbers for kits that cover all three years, 1992, 1993, 1994, no matter what the model.

All of the above is my best guess in a quick look through of various websites. Some of the above may be wrong.

Here is what I am talking about re: Sierra....
They have all the gaskets covered in one kit.

There is no needle valve at the 10 o'clock position.

You have helped identify the carbs as being from a 200 which I didn't know and yes I want to order the correct carb kits. The info you provided will help. Thank you.
The air bleed orifices and main jet seemed to be a somewhat odd combination. larger than most of the ones I looked at for the idle air bleed and smaller than most for the main jet.

If I want to build up my 1987 powerhead as a 200 HP I will probably use these carbs and throttle plates.
The 1987 carbs were not very good.
