6ET-14613-00-00 Exhaust Manifold Gasket for Yamaha 255XD 1800 2021-2026

Exhaust Manifold Gasket for Yamaha

This exhaust manifold gasket seals the joint between the exhaust manifold and the engine on Yamaha 1800 series marine engines, replacing OEM part 6ET-14613-00-00 to stop exhaust leaks and keep the manifold seated correctly.

Overview

This exhaust manifold gasket is a direct-fit sealing component for Yamaha 1800 series marine engines. It creates a tight seal at the manifold mounting surface, preventing exhaust leaks and protecting surrounding components from heat and vibration. Ideal for boat owners and marine mechanics replacing a worn or blown exhaust manifold gasket during routine service or repair.

Built For Performance

• Cross-references OEM part number 6ET-14613-00-00 for straightforward replacement
• Constructed to withstand the high temperatures of marine exhaust systems
• Provides a consistent seal at the manifold-to-engine mounting surface
• Resists compression set to maintain sealing force over service life
• Designed to match the port shape and bolt pattern of the 1800 series exhaust manifold

Fits These Machines

• for Yamaha 255XD 1800 (2021-2026)

On-The-Job Use

• Exhaust manifold replacement or resealing on Yamaha 1800 series boats
• Routine engine maintenance when the manifold is removed
• Repairing exhaust leaks that cause noise or fumes in the engine bay
• Top-end engine service on 255XD models

Good To Know

Q: How do I know if my exhaust manifold gasket needs replacing? A: Common signs include a ticking or hissing exhaust noise, visible soot streaks around the manifold joint, and a burning smell in the engine bay. A failed gasket should be replaced before it causes further exhaust leakage.

Q: Should I replace both manifold gaskets at the same time? A: If both manifolds are being serviced, replacing gaskets on both sides at once saves labor and keeps sealing performance consistent. Always inspect mating surfaces for warping before installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
