Product Description
Mercury Quicksilver 27-524572 is the carburetor-to-intake-manifold base gasket for specified MerCruiser applications with Rochester or Weber four-barrel carburetors.
Key Features
- OEM number: 27-524572.
- Carburetor base / intake-manifold sealing position.
- For matching Rochester and Weber four-barrel carburetor bases.
Compatibility and Fitment
Use on the Rochester or Weber four-barrel carburetor installation that specifies 27-524572. Match the carburetor base, intake arrangement and engine serial-number diagram before ordering; engine displacement alone does not identify the gasket.
Replacement and Installation
Replace a torn, compressed or leaking base gasket when removing the carburetor. Remove old gasket material without damaging the mating surfaces, confirm port alignment, and tighten the carburetor fasteners to the applicable service-manual specification.
Alternate / Superseded Part Numbers
27-524572 supersedes 27-52457. Earlier reference: 27-524571.

Parts Desk Insight
Confirm the carburetor fitted to the engine, especially if it has been replaced. The base pattern is the important match, so a four-barrel description by itself is not enough.
