SUZUKI 11400-87804 GASKET KIT

Function and technical context

This gasket kit brings together the set of sealing elements necessary to guarantee a hermetic seal between the different surfaces of the outboard motor. The gaskets act as a barrier against combustion gas, coolant and oil leaks at critical points such as the cylinder head, exhaust manifold, water pump and engine casing. A deterioration in any of these joints can cause compression losses, engine overheating, lubricant contamination or water entry into the internal circuit, seriously compromising the performance and useful life of the propeller. Having a complete kit facilitates a comprehensive review without the need to purchase loose parts, reducing boat immobilization times.

When to replace this part?

The most common symptoms that indicate outboard gasket failure include the presence of white or bluish smoke in the exhaust, visible loss of coolant, emulsified oil with a milky appearance, drop in compression in one or more cylinders, or abnormal noises when starting from cold. It is recommended to check the condition of the gasket set at each major maintenance intervention – especially after periods of intensive use or after overheating – and replace it whenever the cylinder head or block is disassembled. Acting preventively at the first signs avoids progressive breakdowns that lead to costly rectifications or replacement of the engine block.
