  1. Disconnect the vessel's battery before beginning work.
  2. Drain any relevant fluids, such as coolant or oil, per your service manual.

Troubleshooting & FAQ

How do I know if this gasket fits my specific Verado engine?

This gasket fits 135–200 HP 4-Cylinder Verado models from 2005–2018. For the 200 HP model, it is restricted to serial numbers 0P514869 & Up and 1B517159 & Up. Always cross-reference your engine's required OEM part number (27-895822) with our compatibility list.

What are the signs of a failing engine gasket?

Common symptoms include external oil or coolant leaks, engine overheating, milky or contaminated engine oil (indicating fluid mixing), and poor engine performance or loss of compression. A visual inspection may also reveal cracks, brittleness, or deterioration in the old gasket.

Is any special sealant required for this gasket?

This part is typically designed for a dry-fit installation. Unless your engine’s official service manual explicitly requires a sealant for this specific application, do not use one, as it can interfere with a proper seal.

Why is OEM part number verification important?

Verifying the OEM part number is the most reliable way to ensure you are ordering the correct component. While a part may look similar, small differences in material or dimensions can affect performance and safety. Always check the part number listed in your engine's diagrams or manual.

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.
