Troubleshooting & FAQ

How do I know if this is the correct gasket for my engine?

This gasket is specifically for the port side (cylinder bank 2) of Yamaha 200-250 HP V6 4-Stroke models from 2002 to present. Always verify the part number 6P2-11182-00-00 matches your service manual and check our compatibility table. Do not use for the starboard side.

What are the signs of a blown head gasket?

Common symptoms include engine overheating, a noticeable loss of power, white steam/smoke from the exhaust (indicating coolant is burning), milky or discolored engine oil, or bubbles in the coolant reservoir.

Do I need to use sealant with this gasket?

Most modern multi-layer steel (MLS) gaskets are designed for dry installation. Applying sealants can interfere with the gasket's ability to create a proper seal. Always follow the specific instructions in your engine’s official service manual.

How can I tell which side is the port side?

The port side of a boat is the left side when you are at the stern looking forward toward the bow. On the engine, it corresponds to cylinder bank 2 for this specific Yamaha V6 model.

What is the recommended replacement interval?

A head gasket is not a routine maintenance item. It should only be replaced when it fails or during a major engine overhaul. Its lifespan depends on operating conditions and proper maintenance.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

Shipping speed & cost?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns?
