Product Description
Mercury MerCruiser Quicksilver 27-71614 is the reservoir filler-hole / pressure-cap gasket used in the closed-cooling system on specified MerCruiser engines. The gasket seals at the reservoir cap rather than the thermostat-housing joint.
Key Features
- Mercury OEM gasket, catalog number 27-71614; bare reference 71614.
- Reservoir pressure-cap / filler-hole cap sealing application.
- GTIN: 745061173279.
Engine Compatibility
Applications include the MerCruiser 3.7L family and the 470/485/488 reservoir arrangements that specify this gasket. The 485 2-barrel, 224 cu. in. inline-four diagram lists it for 1980–1982, serial numbers 5685394 through 6218036.
Fitment and Installation
Confirm the reservoir-cap assembly in the engine’s serial-number diagram. Inspect the cap seat and sealing surface for damage, and replace a compressed, split or leaking gasket. Work on the cooling system only when it is cool and depressurized.
Parts Desk Insight
The cap gasket and thermostat-housing gasket are separate parts in the 470-series cooling assembly. Use the cap location to avoid ordering the adjacent seal.
