Sailboat Upgrade: Installing a New Engine Water Pump, Saying Goodbye to Coolant Leaks - Ep. 247

What this video covers
The crew of the 14-year-old sailboat Zephyr addresses two mechanical failures while anchored in Marsh Harbour, The Bahamas: a malfunctioning windlass and a leaking engine coolant pump. The windlass, which frequently skips or stops due to clay mud buildup in the gypsy, requires a thorough cleaning to restore function. Simultaneously, the engine’s original water pump has developed a crack, causing a coolant leak that necessitates topping off the reservoir every hour. James and Natalie choose to replace the entire 14-year-old pump with a new Yanmar unit rather than attempting a seal rebuild, citing the vessel's high annual mileage and the need for long-term reliability. The installation process involves draining the heat exchanger, removing the alternator belt, and disconnecting the thermostat and hoses. The crew successfully removes the old pump, noting significant play in the original bearing, and prepares the engine block for the new component. The installation remains unfinished at the conclusion of the account.
