Head Gasket for Yamaha VXR 1800

This head gasket for Yamaha VXR 1800 personal watercraft seals the cylinder head to the engine block, restoring compression and stopping coolant and combustion leakage, and it cross-references OEM part 6JC-11181-00-00.

Overview

This head gasket is a direct-fit sealing component for the Yamaha VXR 1800 engine, designed to sit between the cylinder head and block under high compression. It keeps combustion gases, coolant, and oil in their correct passages so the engine holds compression and runs at proper temperature. It suits riders replacing a failed or weeping gasket during a top-end rebuild on the Yamaha VXR 1800.

Good To Know

Q: Do I need to replace head bolts when I change this gasket? A: Many marine four-stroke engines use torque-to-yield head bolts that should be replaced on reassembly, so check the service manual for your model. Reusing stretched bolts can result in uneven clamping and a repeat gasket failure.

Q: Should the head and block surfaces be checked before installation? A: Yes, both surfaces should be clean, flat, and free of corrosion or old gasket residue for a proper seal. A warped head will not seal correctly even with a new gasket.

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