Installation Notes

  1. Ensure the engine is off, cool, and disconnected from the battery before starting.
  2. Remove the outboard's lower unit and any other components blocking access to the driveshaft housing.
  3. Carefully remove the old gasket. Thoroughly clean both mating surfaces to remove all old gasket material, sealant, and corrosion. A clean, smooth surface is essential for a proper seal.
  4. Position the new gasket onto the housing, ensuring all bolt holes align perfectly. Do not use any additional sealant unless specified by the engine manufacturer.
  5. Reassemble the driveshaft housing and all related components, torquing fasteners in the correct sequence and to the manufacturer's recommended torque specifications.
  6. After reassembly, reconnect the battery and run the engine, carefully checking for any signs of exhaust or water leaks around the sealed area.

Troubleshooting & FAQ

How do I know if this is the right gasket for my Verado?

This gasket fits a wide range of Verado 200-400 HP 6-cylinder models. The most reliable way to confirm fitment is to find your engine's serial number (usually on a tag on the transom bracket) and verify it falls within one of the ranges listed in the Engine & Model Compatibility table above.

What are the signs of a failed driveshaft housing gasket?

Symptoms of a bad gasket include water contamination in the engine oil (giving it a milky or creamy appearance), visible exhaust or water leaks between the powerhead and driveshaft housing, engine overheating, or a loss of performance. It is a critical seal that should be replaced immediately if failure is suspected.

Is this part the same as an "exhaust plate gasket" or "powerhead base gasket"?

Yes. This component is known by several names, including driveshaft housing gasket, exhaust plate gasket, and powerhead base gasket. As long as the OEM part number 27-889617001 is specified for your engine, this is the correct part.

Should I use sealant when installing this gasket?

Generally, new gaskets of this type are designed to be installed dry on clean, flat surfaces. Applying sealant can sometimes interfere with proper sealing. Always follow the specific instructions in your engine's official service manual for guidance.
