Heavy-Duty Trailer Jack Recommendation
Question:
I have a 22foot Maxum 2200SR3 runabout boat weight with trailer is 4,700 lbs and have now gone through 2 Fulton trailer jacks they ultimately just get stripped and wont raise the boat anymore. I havent seen very many jacks out there that will support my weight am I missing something? When the jacks say theyll support 1,500 lbs, does that mean Im way short, or is the weight capacity based on something Im not considering? In any event, Id like something that can swivel and bolt onto the trailer. Any suggestions/recommendations would be really helpful. I have attached a few pictures of my boat and trailer. Thanks.

Typically the tongue weight and the height needed to clear the towing vehicle coupler are the considering factors for choosing an appropriate trailer jack. It is recommended to choose the jack has a higher capacity than the tongue weight of your trailer. The jack should provide enough lift to clear the vehicle coupler when in a level position by 4 inches.
If your gross trailer weight is 4,700 pounds then the tongue weight of that would be estimated at approximately 10 to 15 percent which would be between 470 pounds and 705 pounds, so a jack with a 1,500 pound capacity would work great. However, selecting a jack with a much higher weight capacity is not an issue and can reduce the effort that the jack exerts, therefore extending the life of the jack.
I have included a helpful article that shows the different types of trailer jacks, and considerations for choosing the proper jack for your trailer application.
The jack the you referenced the Fulton Bolt-Thru Swivel Marine Jack with Dual Wheels # FXPD15L would work for your boat trailer. This product is rated for 1,500 pounds, and provides 12 inches of lift. This jack does have a 5 year limited warranty.
However, if you do not need to use a wheel on your jack you could opt for a higher capacity jack such as the Fulton F2 Swing Up Jack # F1413230134. This jack is rated for 2,000 pounds and provides 10 inches of lift.
The typical reasons that jacks fail is due to over extension and over loading the jack. Since you have already had 2 jacks fail, but I am not sure in what time frame, I would like to caution you to make sure that you do not overload or over extend the jack.
After reviewing your photo one small modification that you can do that would reduce the stress on the jack would be to move the mounting position forward. If you have the space, I recommend mounting this jack forward of the winch stand and just behind the coupler.
Moving the jack mounting position closer to the coupler will increase distance from the axles when acting as a pivot point and will optimize the leverage force of the jack. With this increased leverage it will reduce the amount of weight that the jack will have to lift, and will reduce the force that the jack needs to raise the trailer. By reducing the force the jack needs to exert this will add longevity to the lifespan of the jack.
I have included links to the parts above, a short video and a helpful article for your reference.
