Flushing an inboard motor is an important part of boat maintenance. It helps to keep the engine running smoothly and prevents corrosion and other damage. The process is relatively simple, but it’s important to follow the manufacturer’s instructions for your specific motor. Here’s a step-by-step guide on how to flush an inboard motor.
1. Start by disconnecting the fuel line from the engine and draining any remaining fuel from the tank. This will help prevent any fuel from entering the cooling system during the flushing process.
2. Next, disconnect the raw water intake hose from the engine and attach a garden hose to it instead. Make sure that you have a good seal between the hose and the intake port so that no water can escape during flushing.
3. Turn on the garden hose and allow it to run for several minutes until all of the old coolant has been flushed out of the system. You may need to adjust your garden hose pressure depending on how much pressure is needed to flush out all of the old coolant.
4. Once all of the old coolant has been flushed out, turn off both your garden hose and engine and reconnect your raw water intake hose back onto your engine’s intake port. Make sure that you have a good seal between these two components as well so that no water can escape during operation of your boat’s motor.
5. Finally, fill up your engine with fresh coolant according to manufacturer instructions and reconnect your fuel line back onto your engine before starting it up again for use on your boat or other vessel.
Flushing an inboard motor is an important part of boat maintenance that should be done regularly in order to keep your engine running smoothly and prevent corrosion or other damage from occurring over time due to build-up of old coolant or other debris in its cooling system. Following these steps will help ensure that you are properly flushing out all of the old coolant from your inboard motor before refilling it with fresh coolant for continued use on your boat or other vessel!
