MerCruiser exhaust gaskets & installation kits

Here you will find MerCruiser exhaust gaskets and installation kits for the repair of water-cooled exhaust systems. The range includes gaskets for exhaust manifolds/risers (including full-flow/restrictor versions), exhaust manifolds/manifolds as well as end cap and transom transitions. Ideally, select the appropriate gasket by OEM/reference number and engine variant (e.g. 3.0L, V6, V8). For workshops and resellers, direct purchase/quick entry by part number is the fastest way to order.

MerCruiser exhaust gaskets: small parts, high system effectiveness
Exhaust gaskets are critical service items in the maritime environment: They seal transitions in the exhaust system (exhaust gas elbow/riser, exhaust manifold/manifold, end caps/transom) and prevent consequential damage caused by leaks. In this category, we bundle gaskets and installation kits for MerCruiser exhaust systems - with clear assignment via OEM references.

Assembly logic: how customers find the right gasket

  • Exhaust elbow/riser gaskets: These include variants such as full-flow gaskets (e.g. 864547A02) as well as model-specific exhaust elbow gaskets (e.g. 99777Q02 context).

  • Exhaust manifold/manifold gaskets: Gasket kits are available for various engine families (e.g. GM/Ford V6/V8).

  • End cap/transom transitions: Specific gaskets such as end cap gaskets (MD480431) or sealing rings for transom/exhaust manifold (MD41802) are typical "missing part stoppers".

Assembly kits: the most efficient way to order
Assembly kits reduce reorders and downtime. Your range includes an exhaust manifold assembly kit for MerCruiser V6/V8 and an exhaust manifold assembly kit for GM V8. These sets should be integrated at category level as "top tiles" and in the footer text as a clear recommendation ("set instead of individual parts").

Part numbers first & direct purchase
In practice, workshops order exhaust gaskets using part numbers. Your direct purchase/quick checkout is ideal for this (enter part numbers → quick checkout). Therefore, place a prominent part number search ("Enter OEM no.") above the listing.

Checklist for reducing incorrect orders

  1. Determine engine (3.0L/V6/V8) and exhaust assembly → 2) Match OEM no. → 3) Check version (full-flow/restrictor/closed) → 4) Select assembly set if possible → 5) Add assembly parts (end caps/taps/plugs) if necessary.
