Mercury MerCruiser / Quicksilver Gaskets & Seals

Authorized Mercury Marine Dealer

Mercury Marine and Quicksilver gaskets and seals are used throughout engine, cooling, drive, and gearcase systems to help prevent leaks, maintain proper pressure, and protect critical marine components. As an authorized Mercury Marine dealer, Marisol Marine supplies genuine Mercury and Quicksilver sealing parts designed for correct fit, reliable compression, and long service life in marine environments.

Marine engines operate under continuous heavy load with constant exposure to moisture, heat, pressure, and saltwater conditions. Genuine OEM Mercury gaskets, seals, O-rings, and washers are engineered to withstand these demands while helping maintain dependable engine and drive system performance.

Engine Gaskets

Engine gaskets seal major engine components together to help contain combustion pressure, oil, coolant, and exhaust flow while preventing leaks between mating surfaces.

Cylinder Head Gaskets Intake Manifold Gaskets Exhaust Manifold Gaskets Valve Cover Gaskets Oil Pan Gaskets

Cooling System Gaskets

Cooling system gaskets help maintain proper water and coolant flow while preventing leaks around pumps, housings, and circulation components.

Water Pump Gaskets Thermostat Housing Gaskets Circulation Pump Gaskets

Drive & Gearcase Gaskets

Drive and gearcase gaskets seal sterndrive and lower unit components to help protect internal gears, bearings, and lubrication systems from water intrusion.

Gearcase Gaskets Bell Housing Gaskets Water Pump Face Plate Gaskets MerCruiser Gaskets

Common Marine Seals

Seals are typically rubber or polymer components used where rotating shafts, oil passages, drain plugs, and fittings must remain leak-free while still allowing movement.

Prop Shaft Seals Driveshaft Seals Oil Seals O-Rings Drain Screw Washers
⚠️ Always confirm gasket and seal fitment by engine serial number, drive model, and application before ordering.
