The
trailer jack you choose must be rated to support the tongue weight of your trailer when loaded with your boat. We carry a variety of
trailer jacks with the heaviest models capable of supporting tongue weights up to 5,000 pounds. You will also need to decide between a jack with a foot or a wheel. If your boat is too heavy to move around manually, then a jack with a foot will work well. If your boat is light enough, a jack with a caster-style wheel will allow you to move the trailer around, which can help when you are hooking the trailer up to the tow vehicle. Large diameter wheels tend to move more freely than small diameter wheels, especially over uneven terrain.
As for the trailer jack,you should also consider where you use your boat. Saltwater boaters need jacks that are corrosion resistant. These can be powder-coated steel, anodized aluminum or zinc-plated steel. Other considerations include the amount of "travel", which is the jack’s up/down movement in inches and the maximum height of the jack.
