A tongue jack supports the loaded tongue, not the trailer’s entire weight. Select lift and static capacity from the measured loaded tongue weight, then match the trailer’s A-frame, side bracket or pipe mount. Saltwater use makes corrosion finish, lubrication and rinsing especially important.

Buying tips
- Measure loaded tongue weight with the boat, fuel and gear configured for travel; do not select from boat or trailer gross weight alone.
- A wheel is useful on smooth ground but a footplate is steadier on soft or uneven launch areas.
- Rinse saltwater exposure, inspect the mount and fasteners, and lubricate only as the jack maker specifies.
