Installation Notes

  1. Disconnect the battery and relieve any pressure in the fuel system.
  2. Drain the engine coolant completely.
  3. Remove components obstructing access to the cylinder head, such as the intake and exhaust manifolds.
  4. Loosen and remove the cylinder head bolts in the reverse order of the manufacturer's specified tightening sequence.
  5. Carefully lift the cylinder head from the engine block. Avoid prying, which can damage the mating surfaces.
  6. Thoroughly clean all old gasket material, oil, and debris from the surfaces of the head and block.
  7. Inspect both mating surfaces for flatness using a straightedge and feeler gauge. Resurface if they are not within specifications.
  8. Position the new gasket correctly on the engine block, aligning it with any dowel pins.
  9. Carefully lower the cylinder head back into place over the gasket and dowels.
  10. Install new or verified head bolts. Tighten them in sequence and stages to the manufacturer's torque specifications.
  11. Reassemble all components that were previously removed.
  12. Refill the cooling system, reconnect the battery, and start the engine to check for any leaks.

Troubleshooting & FAQ

How do I know if this gasket will fit my engine?

This gasket is for Johnson/Evinrude 90° V6 3.3L Loopcharged engines (200-250 HP) from 1994–2001 with 3.6875" (93.7 mm) pistons. Always cross-reference your engine's model number with our compatibility list before ordering.

What are the signs of a failed cylinder head gasket?

Common symptoms include engine overheating, a noticeable loss of power, white smoke from the exhaust (burning coolant), milky or frothy engine oil, and bubbling in the radiator or coolant reservoir.

Is this a single gasket or a pair?

This listing is for a single cylinder head gasket. Since V6 engines have two cylinder banks, you will need to purchase two if you are servicing both heads.

Do I need to use sealant with this gasket?

No. This gasket is designed to be installed dry. Applying sealant can interfere with its ability to seal properly, causing hot spots, improper torque, and potential premature failure.

Can I reuse my old head bolts?

It is strongly recommended to use new cylinder head bolts. Old bolts can stretch (yield) upon first use and may not achieve the correct clamping force when re-torqued, leading to leaks and gasket failure.

What is the recommended replacement interval?

Head gaskets are typically replaced only when they fail or during a major engine overhaul, not on a routine service schedule.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9001 facility, batch-inspected for consistency.
