HOW TO WINTERIZE YOUR BOAT LIFT

If you live in a colder climate, you are no stranger to winterization. Boat lift winterizing is just another thing you need to do before the cold weather sets in to make sure winter does not take its toll.

Freezing temperatures can severely damage the hydraulic systems and frames on your boat lift. Severe storms and ice build-up can also cause damage. Ice build-up can create pressure that shifts your lift and dock out of alignment, leading to expensive repairs. This will take money out of your pocket and delay your time to enjoy your boat, which is why you own it in the first place. Proper boat lift winterization is a preventative measure that takes less time and money, and can extend your boat lift’s lifespan. 

UNDERSTANDING YOUR BOAT LIFT SYSTEM

The first step in boat lift winterization is understanding your boat lift system. The main components of a boat lift are:

• The bunks or cradles, which securely support the boat’s hull

• The framework, which provides structural stability and holds the cradles in place

• The winch system, including the spool, which raises and lowers the boat

• The cables or straps, which connect the boat to the lift. Cables bear most of the boat’s weight and need to be frequently checked for wear and tear.

The three main types of winch systems are hydraulic, electric, and manual. Each has different crucial components and specific requirements that need to be identified and assessed in the winterization process. 

HYDRAULIC LIFT

Knowing how to winterize a hydraulic boat lift includes understanding its key parts, including:

• The electric pump motor that moves hydraulic fluid to the cylinders

• The reservoir that stores the hydraulic fluid

• The cylinders and pistons that help lift the boat

• The control valves and heat exchanger that regulate the flow and temperature of the hydraulic fluid

Each one of these parts needs attention for hydraulic lift winterization.
