Why is my Regal 2000 ES Boat engine overheating?

If your Regal Boat engine is overheating, several factors could be the cause. Start by checking for any blockages in the water pick-up feeds and clear them if necessary. Ensure that the cooling system drain plugs are properly installed. Inspect the cooling system for any leaks and repair them. Examine the impeller for damage or blockages. If the propeller is over-propped, change it to one suitable for the operating conditions. Replace the oil filter if there's debris in the oil. Replace a faulty thermostat or gauge. Finally, flush the raw water cooling system if it has corroded.
