15521 Gasket | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta gasket is a formed OEM sealing component used in the engine or sterndrive sealing joint. It is manufactured to the original Volvo Penta dimensions and interface requirements so the mating joint retains its intended fluid, gas or contamination barrier. Legacy service-kit gasket documented in MD2B, MD7 and MD17C repair/on-board kit arrangements, with additional OMC/Volvo Penta sterndrive-era use. In service, it seals the matched joint face against fluid, gas or air leakage according to the original assembly location. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 15521 against the installed assembly before ordering.

🚤 Compatibility

• Engine Family: MD, MB, D, MS, AQD

⚙️ Key Features

• OEM Volvo Penta part number 15521
• Genuine Volvo Penta replacement gasket
• Fits Volvo Penta 2001, 2002 and 2003 series engines plus MD, MS, AQD and 120S drive-related units
• Single-use sealing component - recommended for renewal whenever the joint is opened

🔌 Function

The gasket forms a compressible seal between two mating components so that fluid or pressure cannot escape at the joint. It compensates for minor surface irregularities and maintains a leak-free connection once the fastenings are torqued.

⚠️ Common Signs of Failure

• Visible weeping, seepage or drips at the joint face
• Loss of pressure or fluid level in the affected circuit
• Hardened, brittle, cracked or flattened gasket material on removal
• Staining, residue or corrosion tracks around the mating surfaces
• Repeated need to retighten fasteners to control a leak

🛠️ Service Notes

• Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
• Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
• Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
• Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
• Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
