Installation Notes

Disconnect the battery and ensure the engine is cool. Drain the engine oil and coolant.
Remove the engine cover and any components obstructing access to the cylinder head, such as the intake and exhaust manifolds.
Carefully loosen the cylinder head bolts in the reverse order of the manufacturer's tightening sequence, typically starting from the outside and working inward.
Lift the cylinder head off the engine block. Do not pry between the mating surfaces.
Remove the old head gasket and thoroughly clean both the cylinder head and engine block surfaces of any old gasket material, sealant, or carbon buildup.
Place the new head gasket onto the engine block, ensuring it is correctly oriented with any locating dowels.
Carefully lower the cylinder head back into position on the block.
Install the head bolts and tighten them in stages, following the specific torque sequence and values recommended in your service manual.
Reinstall all previously removed components.
Refill the engine with fresh oil and coolant.
Reconnect the battery, start the engine, and check for any leaks.

Troubleshooting & FAQ

How do I know if this gasket fits my Suzuki engine?

This gasket is designed for Suzuki DF9.9 and DF15 4-stroke models from 1996 through 2011. It's crucial to check your engine's model and year against the compatibility table. For example, it fits DF9.9 models from 1996–2003 and the DF9.9 (R) series from 2004–2011.

What are the signs of a failing head gasket?

Common symptoms include engine overheating, a loss of power, white smoke from the exhaust (coolant burning), milky or frothy engine oil (coolant mixing with oil), or external oil and coolant leaks from the seam between the cylinder head and engine block.

Is this a direct replacement for Johnson/Evinrude 5033046?

Yes, this gasket is cross-referenced as a direct replacement for Johnson/Evinrude (BRP) part number 5033046 on compatible 9.9 and 15 HP 4-stroke outboards.

What is the difference between Suzuki part numbers 11141-93E01, 11141-93E10, and 11141-93E20?

This represents a supersession chain where 11141-93E20 is the latest version, replacing the older 11141-93E10 and 11141-93E01 parts. The newest part is backward compatible with engines that originally used the older numbers.

How often should a cylinder head gasket be replaced?

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