Boat Trailer Jack Buying Guide
The standard tongue jack that comes with the trailer is often poor quality and a pain to use.
Many can be fairly old too, which means they can be corroded and are simply not up to the job anymore.
Upgrading to the recommended trailer jacks above will see the movement of your trailer around the boatyard become much easier as well as hitching it onto your vehicle.
Trailer jacks are not as straight forward as they seem and there are many variations in terms of tongue weights, extended heights, and construction.
Below are some factors you should consider before replacing your current jack.
The downward pressure the coupler puts onto the hitch ball is known as the trailer tongue weight.
This weight is usually 10 to 15 percent of the gross trailer weight (with the boat attached).
You will want to ensure you get a trailer tongue jack that supports a weight larger than your gross trailer weight.
For example, if the trailer has a gross weight of 4,000 LBS, it will need to have a tongue weight of at least 400 to 600 LBS.
The tongue of the trailer will need to reach the trailer hitch of your vehicle. Therefore it’s important that you measure the height from the floor to the trailer hitch before purchasing a boat trailer jack.
Failing to make the correct calculation may leave you in a bit of trouble when trying to lift the trailer to your hitch.
However, it should also be short enough when retracted so that it has enough ground clearance when moving the trailer around the boatyard.
As the boat trailer jack will be subjected to saltwater and general marine conditions, it’s vital that it is suitably protected.
Unlike the trailer that will most likely be galvanized, most trailer jacks are not and it is up to the manufacturer to provide protection.
Most will use a zinc coating but as good practice, you should always clean the jack after being used in saltwater.
Upgrading your old and corroded boat trailer jack is a worthwhile investment.
The latest available are designed to be installed with ease and provide fast cranking.
There is a wide variety of boat trailer jacks available and we strongly recommend avoiding the cheap alternative available.
