The PCM 96331 Cover Drain Exhaust Gasket is a marine exhaust sealing gasket used on Pleasurecraft Marine / PCM engine applications where the exhaust drain cover plate requires resealing. This gasket seals the cover-to-exhaust component joint to help prevent raw cooling water, moisture, and exhaust residue from leaking into the engine compartment. It is typically serviced during exhaust manifold, riser, drain-cover, or winterization-related maintenance where the cover plate has been removed.
Key Features
- PCM part number: 96331
- Product type: Exhaust drain cover gasket
- Application location: Exhaust drain cover plate area
- Primary function: Seals the drain cover joint against water and exhaust-side leakage
- System: Marine engine exhaust / raw-water cooling interface
- Material type: Marine exhaust gasket material suitable for heat, vibration, and water exposure
- Service use: Exhaust cover reseal, manifold service, leak repair, and cooling-system maintenance
- Brand application: PCM / Pleasurecraft Marine engines where the parts diagram calls for 96331
Engine Compatibility
This gasket is intended for PCM marine engine applications that specify 96331 in the exhaust or drain-cover parts breakdown. Exact fitment should be confirmed by engine model, serial number, exhaust manifold style, drain cover design, and PCM parts diagram.
Do not select this gasket by engine displacement alone. PCM 5.0L, 5.7L, 6.0L, and other gasoline marine engines can use different exhaust manifold and drain-cover configurations depending on model year and cooling layout.
Serial Number Fitment Notice
Confirm the PCM engine serial number and exhaust manifold diagram before ordering. The correct gasket depends on the drain cover plate shape, fastener layout, manifold casting, and whether the engine uses the same exhaust drain-cover assembly shown for part number 96331.
If the old gasket is available, compare the outline, bolt holes, water passages, and sealing surface before installation.
When This Part Needs Replacement
Replace this gasket whenever the exhaust drain cover plate is removed. It should also be replaced if there are signs of water dripping from the cover, rust trails, salt deposits, steam marks, exhaust staining, corrosion around the cover edge, or leakage after winterization or manifold service.
A used exhaust gasket should not be reused after disassembly, since heat cycling, compression set, and corrosion can prevent it from sealing properly a second time.
Installation Notes
Clean the drain cover plate and exhaust component sealing surface before installing the new gasket. Remove old gasket material carefully without gouging the mating surfaces. Inspect the drain cover, fasteners, threads, manifold casting, riser area, and nearby cooling passages for corrosion or blockage before reassembly.
Follow the PCM service procedure for fastener tightening sequence and torque. Do not use sealant unless the service manual specifically calls for it. If the cover is being removed as part of a larger exhaust service, inspect related manifold gaskets, riser gaskets, drain plugs, hoses, clamps, and raw-water passages at the same time.
Alternate/Superseded Part Numbers
- PCM: 96331
- Common description: Cover Drain Exhaust Gasket
- Related exhaust service references: PCM 97498 and RM0002 may appear in nearby exhaust manifold or riser service work, but should not be treated as direct replacements for 96331 unless confirmed by parts diagram.
Parts Desk Insight
This is a diagram-specific gasket. The safest way to match it is by PCM serial number and exhaust manifold layout, not by engine size alone. If the drain cover is already removed, replacing the gasket during reassembly is inexpensive protection against repeat water leaks in the engine compartment.
