Description
Technical Overview & Product Details
The cylinder head outlet area is subject to high-velocity flow and significant thermal expansion. The 146673-13210 gasket acts as the critical barrier, maintaining a hermetic seal against the housing flange. By compensating for micro-movements and surface irregularities, this gasket prevents the loss of pressure or coolant, which is vital for the thermal management and exhaust efficiency of the engine.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 146673-13210.
- Component Type: Cylinder Head Outlet Gasket.
- Material: High-temperature resistant composite or reinforced metallic material, selected for elasticity and durability.
- Application: Sealing the connection between the cylinder head outlet flange and the corresponding manifold/piping.
Key Features & Performance
- Thermal Resilience: Formulated to maintain structural integrity and sealing pressure despite constant exposure to high-temperature exhaust gases or coolant.
- Precision Fit: Machined to exact port dimensions to ensure an unobstructed flow path, preventing turbulence or restriction within the outlet assembly.
- Seal Reliability: Designed to provide an excellent crush-fit, compensating for flange surface variations to eliminate leaks under varying engine loads.
- Chemical Compatibility: The material is resistant to degradation from coolant additives, oil residues, and exhaust condensate, ensuring long-term serviceability.
Why Source from Heybeli Marine?
A failing outlet gasket can result in exhaust gas leaks (creating soot and noise) or coolant loss (leading to overheating). Heybeli Marine protects your vessel’s performance with:

- Global Strategic Logistics: We maintain a ready-to-ship inventory of these essential seals, ensuring they reach your vessel or shipyard quickly to avoid maintenance delays.
- Quality Assurance: Every batch undergoes rigorous inspection to ensure the gasket maintains its shape and seal integrity under the demanding conditions of maritime use.
- Complete Overhaul Support: We provide these gaskets alongside exhaust manifold components and piping seals to help you conduct a professional, total top-end rebuild.
Technical Maintenance Note:
When installing the 146673-13210, it is vital to clean both mating surfaces thoroughly to remove all traces of the old gasket, corrosion, or carbon buildup. Using a wire brush or scraper, ensure the metal surfaces are smooth; a pitted surface will significantly reduce the lifespan of the new gasket. Always install the gasket dry unless specified otherwise in the Yanmar service manual. Tighten the flange bolts evenly in a cross-pattern to ensure the gasket is compressed uniformly, which prevents “cocking” of the flange and potential leaks.
