No, you should not use caustic soda to flush a 2-stroke outboard engine. Caustic soda is highly corrosive and can damage the engine's internal components and cooling system. Instead, it's best to use fresh water or a specially formulated flushing solution designed for marine engines to effectively remove salt and contaminants without risking damage. Always refer to the manufacturer's guidelines for proper maintenance procedures.

What is the flush screw for on your 9.8 Mercury?

The flush screw on a 9.8 Mercury outboard motor is used to allow water to flow through the cooling system for flushing and cleaning purposes. By attaching a garden hose to the flush port, you can run fresh water through the engine to remove salt, debris, and buildup after use in saltwater or contaminated environments. This helps prevent corrosion and ensures optimal performance and longevity of the motor. Always refer to the owner's manual for specific instructions on using the flush screw.
