Description

Mercury MerCruiser Quicksilver 804844002 is a genuine carburetor repair kit for select MerCruiser engines using the newer MerCarb two-barrel carburetor with the current side-fill accelerator pump cavity. Mercury describes it for select 4-cylinder, V6, and V8 sterndrive and inboard engines built between 1986 and 2016.

Engine Compatibility

Current Mercury and OEM parts sources most consistently tie 804844002 to select MerCruiser sterndrive and inboard engines from 1986–2016 using the newer MerCarb 2-barrel carburetor. Public fitment references commonly summarize this as select 4-cylinder, V6, and V8 packages, including common GM-based 305 and 350 cid applications where that carburetor version was used. Final fitment still depends on the exact carburetor version and engine serial number.

Serial Number Fitment Notice

Carburetor repair kit fitment can vary by engine serial number, MerCarb version, and accelerator pump cavity style. Confirm part number 804844002 against your exact MerCruiser engine serial number before ordering to make sure you are matching the correct rebuild kit to the carburetor on the engine.

When This Part Needs Replacement

Replace or use this repair kit when the carburetor shows signs of fuel leakage, poor idle quality, stumble on acceleration, hard starting, gasket deterioration, or when the carb is being serviced and the internal soft parts need to be renewed. Since this is a repair kit, it is best suited for carburetors that are structurally sound but need a proper refresh of the wear and sealing components.

Installation Notes

Match the kit by serial number and by the carburetor’s side-fill accelerator pump cavity style before opening the job. Because Mercury specifically calls out the newer MerCarb 2-barrel version, it is important not to order by engine family alone. Use the correct MerCruiser service manual or owner’s manual for the exact application and rebuild procedure.

Alternate/Superseded Part Numbers

Current sources reviewed consistently identify 804844002 as the active ordering number. In dealer and OEM catalog formats, it is also commonly shown as 3302-804844002.

Parts Desk Insight

With MerCarb kits, the biggest mistake is ordering by “2-barrel carb” alone. Mercury is specific here: this kit is for the newer MerCarb with the current side-fill accelerator pump cavity. That detail matters more than broad engine family fitment, because similar-looking MerCarb units can use different internal service kits.
