Importance of Winterizing Your Boat at Sunnyside Marina!

Winter in the Northern California Sierra Nevada, especially aroundĀ Lake Tahoe Boat Rental, brings a picturesque snowy landscape that unfortunately can spell disaster for unprepared boat owners. At Sunnyside Marina, we stress the importance of winterizing your boat to prevent significant damage and ensure that your vessel remains in peak condition for the next season.

When temperatures consistently hit 25 degrees Fahrenheit or lower, the risk to boats increases significantly. Water in the engine block can freeze, expand, and cause the block to crack, leading to costly repairs. Additionally, if not properly treated, oil and fuel can degrade, affecting performance when you most need reliability. Other common issues include hoses splitting due to the expanding ice, accelerated corrosion of metal parts, and battery damage. These problems are particularly prevalent in inboard/outboard and v-drive boats, the types most commonly found at Lake Tahoe and stored at our marina.
