Product reviewsFor Mercury Marine 3.0L 4.3L 5.0L 5.7L 3302-804844002 Carburetor Repair Kit

Awesome product

Awesome rebuild kit with high quality American made components. Have used 3 kits so far on customers boats and have been very pleased. Comes a new mixture screw which is very handy for carbs with tamper resistant mixture screws installed and a handy float hieght guage and a set of instructions showing each engine application's specs for float height, choke setting, etc. We'll put together kits, my go to source now.Read full review...

Rebuild kit

Kit is good except all the instructions are for the float kit that is the plastic type. Paid extra for the brass float and no markings for float toe. Was not able to set float correct and so I had to use old float, wasted money for the brass float...Read full review...

Complete Rebuild Kit

Kit contains clear instructions and every part you'd expect in a rebuild kit, i.e. pretty much everything except new jets and floats.

The kit services several different carburetor versions, so not every piece will be used in all applications. The gaskets and such utilized in this case were all cut identical to OEM with no odd trimming required, and no questionable o-ring seating.

Quality of the parts and gasket materials indicated by experience. Kit was Installed and ran for about 1/2 a season (3+ months), then over-wintered (in PA). Started 2nd season without any further adjustment and no leakage of fuel has been detected.Read full review...

This is the BEST rebuild kit you can buy.

Only uscarburetors offered the carb rebuild kit _with_ the float and this is definitely the one to get. Mercruiser 4 cyl engines emit a lot of vibration which wears out the pivot holes in the float, especially if you have old-style solid needle without a spring. This kit cured all flooding issues and my engine runs like new again!Read full review...

Very complete kit

Almost everything you need (does not include the float, but it rarely goes bad). Came with some extra parts for a carburetor slightly different than mine. With this kit I was able to completely rebuild my carburetor. Boat running fine again. And price is very good too.Read full review...
