Essential features

Material

Due to the corrosive effects of salt and brackish water environments. it’s important that your trailer jack be made of materials that will resist pitting and rust. Look for a jack constructed of zinc-plated steel or aluminum. Aluminum is lightweight; steel. while heavier. is extra strong. Both offer excellent resistance to corrosion. resulting in longer service life.

Installation

Bolt-on trailer jacks are perfect for replacing your old jack. Bolt-ons offer better flexibility and quick installation. The mounting plate should have extra bolt holes to accommodate common trailer tongue dimensions. Some mounting plates have a rotating collar that allows the jack to swivel into a horizontal position during transportation.

Stability

A jack should keep your boat trailer level and stable under full load when not hitched to your vehicle. In addition to heavy-duty construction. the jack’s base will factor heavily in its stability. The base will be either a 6?C8 wheel or foot plate. A wheel is ideal for average loads on a paved surface; a wider wheel (> 2 in.) will offer better stability under heavier loads. A foot plate is best for loads over 2.000 lbs. on any surface. including dirt or pebbles.

Choosing a Trailer Jack: Height

When fully extended. the jack should raise the trailer tongue higher than the top of the hitch ball (see Extended Height in the comparison table). so that the tongue can be lowered onto the ball and secured.

Choosing a Trailer Jack: Weight Capacity

The jack should be able to handle 10-15% of the combined weight of the trailer and boat (gross weight). For example. a gross weight of 10.000 lbs. will require a jack with a weight capacity of at least 1.000 lbs.

Choosing a Trailer Jack: Base

When choosing a jack. consider the type of surface and the jack’s weight capacity. A wheel is ideal for average loads on a paved surface; a foot plate is best for loads over 2.000 lbs. on any surface ?C including dirt.

Choosing a Trailer Jack: Manual or Electric

If you don’t mind raising and lowering your jack by hand. choose a manual crank model. Otherwise. go with an electric jack. These are more expensive but offer faster raising and lowering at the touch of a button.
