The Importance of a Water Pump for 3.0 Mercruiser

I have been a boat owner for many years and have learned the hard way that proper maintenance is crucial in keeping my boat running smoothly. One important component that I always make sure to check and replace when needed is the water pump for my 3.0 Mercruiser engine.
