Trailer Jack Replacement Recommendation for Pro Series 1,000 lb Jack

Question:

Without being able to look at the products first hand like I could in a store I wanted to see a good product for my jack on the front of my 21' ski boat. I have a new 1000 pound swivel C Clip jack on the front of the boat that didn't hold up one year. The mechanical parts inside are about to stop moving. I need a heavier one. I took a couple pictures of what I have and they are attached. The original mount is welded to the frame and I would like to keep it. The boat and trailer combined weighs 4000 pounds total, the front tongue weight I don't exactly know. More than I would attempt to lift by hand I know. What jack would you recommend for my boat trailer?

Thank you so much for the pictures and descriptions!

It looks like you have the Pro Series Snap-Ring Swivel Marine Jack # PSEJ10000101 so for a replacement that will install directly to the mounting plate that is already welded on your trailer frame I recommend the Fulton Round, Snap-Ring Swivel Marine Jack # FTJ12000101.

This typically bolts onto the trailer frame but the snap ring is the same so you can just discard the mounting brackets that come with this jack. The Fulton jack has a slightly higher weight rating at 1,200 lbs, it comes with a 3-year warranty, and has a 600-hour salt spray rating as opposed to your Pro Series which doesn't have that rating.

If you want something more heavy-duty then I recommend the Extreme Off-Road Swing-Up Trailer Jack w/ Dual Wheels # ORJW750BD. This jack is rated for 1,650 lbs static (not moving) and 1,100 lbs dynamic (when moving). It is made in Australia and designed around the rugged terrain that you find there so you can be confident that this will handle pretty much anything you throw at it. For this jack (and anything else with a higher capacity rating) you will need to use a different mounting method.

Please note that your trailer tongue weight should be 10-15% of the loaded weight of your trailer. If your boat and trailer weigh in at 4,000 lbs then your tongue weight should be 400 lbs - 600 lbs. Your Pro Series jack should have been able to handle this just fine since it is rated for 1,000 lbs, so I recommend checking your loaded tongue weight just to make sure you didn't overload the jack. If you don't already have a scale I recommend using the etrailer Trailer Tongue Weight Scale # e99044 so that you can easily know what your tongue weight is no matter where you are at.
