How much water should you leave in your tank for crew/engine protection?

• A. One hundred gallons
• B. Fifty gallons
• C. One hundred fifty gallons
• D. A quarter tank

Answer: (A)

Having a water reserve in the tank is essential to protect both the engine and the crew during times you can’t immediately refill or when you need a little extra buffer while repositioning. Keeping about 100 gallons in the tank provides enough water to keep the pump cooled and primed, supports the crew’s protection needs if a quick defensive action is required, and buys you time to secure a refill. Too little water, like 50 gallons, risks overheating or losing pump prime before you reach a water source. Too much, such as 150 gallons, reduces the reserve you have for those critical moments. A quarter tank isn’t a fixed, reliable minimum because it depends on tank size, so 100 gallons is a practical, consistent standard.
