Buying Guide for Electric Jacks for Boat Trailers
Lifting Capacity
Select an electric jack that can handle at least the gross trailer weight of your boat. Models range from 2,500 lbs to upwards of 7,500 lbs for heavy-duty applications. Always choose a jack with capacity exceeding your trailer’s load for safety and longevity.
Mounting Style
Check if the jack supports side mount or insert mount for compatibility with your trailer frame. Some jacks offer dual mounting options to increase versatility during installation.
Corrosion Resistance
Boat trailers are exposed to water and salt, so select jacks coated with corrosion-resistant finishes like Sharkskin, stainless steel components, or rust-proof coatings. This ensures durability and reduces maintenance.
Power Source and Motor
Most electric jacks operate on 12V DC from your trailer battery or vehicle system. Look for brushless motors or advanced ball screw mechanisms for quieter, smoother, and more efficient lifting. Built-in circuit breakers help protect electrical components from overload.
Travel Range and Drop Leg Features
Consider total vertical travel needed to raise and lower your trailer. Models with spring-loaded drop legs provide additional reach for easier stability on uneven ground, which is beneficial when using weight distribution systems.
Additional Features
- LED Lights: Helpful for nighttime operations
- Waterproof Covers: Shield jacks from weather elements
- Rotating Installation: Allows adjustment to prevent interference with gates or other trailer parts
- Safety Circuitry: Built-in circuit breakers prevent motor burnout
