Flush the Engine
Whether you go on a salt water or fresh water boat outing, you will need to flush your outboard engine when you get back. If you have an older motor, you will need to get a set of flushing earmuffs, which are two flexible rubber seals that are attached to a metal clamp. Attach one side to a garden hose and the other one can be used to plug the water intake. Attach the garden hose to the earmuffs and turn the water on. If your outboard motor is a new model, you will have mounts, and will not need to use the earmuffs. Start the engine and let the water flush the system. You will need to stay clear of the prop and make sure the motor is not in gear.
When you open the tap and start flushing the motor, check the pump to ensure it has good water flow. When you put your finger through the stream of water coming out of the motor, it should be warm and not hot. If the output is not strong, check the outflow tube for any debris that may be preventing the flow of water. If there is debris, shut off the engine and use a small piece of wire to remove the debris from the tube and restart the engine again to flush it properly.
